Mac OS X Juni Going back to a snapshot means that all changes that had been made to the machine’s disks, file by file and bit by bit, will be undone as well.

Files that were since created will disappear, files that were deleted will be restored, changes to files will be reverted. Strictly speaking, this is only true for virtual hard disks in “normal” mode. You can configure disks to behave differently with snapshots, see Section 5. In technical terms, it is not the virtual disk itself that is restored when a snapshot is restored.

Instead, when a snapshot is taken, Oracle VM VirtualBox creates differencing images which contain only the changes since the snapshot were taken. When the snapshot is restored, Oracle VM VirtualBox throws away that differencing image, thus going back to the previous state.

This is both faster and uses less disk space. For the details, which can be complex, see Section 5. Creating the differencing image as such does not occupy much space on the host disk initially, since the differencing image will initially be empty and grow dynamically later with each write operation to the disk. The longer you use the machine after having created the snapshot, however, the more the differencing image will grow in size.

If you took a snapshot while the machine was running, the memory state of the machine is also saved in the snapshot. This is in the same way that memory can be saved when you close a VM window. When you restore such a snapshot, execution resumes at exactly the point when the snapshot was taken.

The memory state file can be as large as the memory size of the VM and will therefore occupy considerable disk space. When you select a virtual machine from the list in the VirtualBox Manager window, you will see a summary of that machine’s settings on the right. Clicking on Settings displays a window, where you can configure many of the properties of the selected VM.

But be careful when changing VM settings. It is possible to change all VM settings after installing a guest OS, but certain changes might prevent a guest OS from functioning correctly if done after installation.

This is because the Settings dialog enables you to change fundamental characteristics of the virtual machine that is created for your guest OS. For example, the guest OS may not perform well if half of its memory is taken away. As a result, if the Settings button is disabled, shut down the current VM first. Oracle VM VirtualBox provides a wide range of parameters that can be changed for a virtual machine.

The various settings that can be changed in the Settings window are described in detail in Chapter 3, Configuring Virtual Machines. Even more parameters are available when using the VBoxManage command line interface. Removing a VM. The confirmation dialog enables you to specify whether to only remove the VM from the list of machines or to remove the files associated with the VM.

Note that the Remove menu item is disabled while a VM is running. Moving a VM. Note that the Move menu item is disabled while a VM is running.

You can create a full copy or a linked copy of an existing VM. This copy is called a clone. The Clone Virtual Machine wizard guides you through the cloning process. Start the wizard by clicking Clone in the right-click menu of the VirtualBox Manager’s machine list or in the Snapshots view of the selected VM. Specify a new Name for the clone. You can choose a Path for the cloned virtual machine, otherwise Oracle VM VirtualBox uses the default machines folder. The Clone Type option specifies whether to create a clone linked to the source VM or to create a fully independent clone:.

Full Clone: Copies all dependent disk images to the new VM folder. A full clone can operate fully without the source VM. Linked Clone: Creates new differencing disk images based on the source VM disk images. The Snapshots option specifies whether to create a clone of the current machine state only or of everything. Everything: Clones the current machine state and all its snapshots. Current Machine State and All Children:. Clones a VM snapshot and all its child snapshots.

This is the default setting. This is the best option when both the source VM and the cloned VM must operate on the same network. The duration of the clone operation depends on the size and number of attached disk images. In addition, the clone operation saves all the differencing disk images of a snapshot.

Note that the Clone menu item is disabled while a machine is running. Oracle VM VirtualBox can import and export virtual machines in the following formats:. This is the industry-standard format.

Cloud service formats. Export to and import from cloud services such as Oracle Cloud Infrastructure is supported. OVF is a cross-platform standard supported by many virtualization products which enables the creation of ready-made virtual machines that can then be imported into a hypervisor such as Oracle VM VirtualBox.

Using OVF enables packaging of virtual appliances. These are disk images, together with configuration settings that can be distributed easily. This way one can offer complete ready-to-use software packages, including OSes with applications, that need no configuration or installation except for importing into Oracle VM VirtualBox. In particular, no guarantee is made that Oracle VM VirtualBox supports all appliances created by other virtualization software.

For a list of known limitations, see Chapter 14, Known Limitations. They can come in several files, as one or several disk images, typically in the widely-used VMDK format.

They also include a textual description file in an XML dialect with an. These files must then reside in the same directory for Oracle VM VirtualBox to be able to import them.

Alternatively, the above files can be packed together into a single archive file, typically with an. OVF cannot describe snapshots that were taken for a virtual machine. As a result, when you export a virtual machine that has snapshots, only the current state of the machine will be exported.

The disk images in the export will have a flattened state identical to the current state of the virtual machine. From the file dialog, go to the file with either the.

Click Import to open the Appliance Settings screen. You can change this behavior by using the Primary Group setting for the VM. Base Folder: Specifies the directory on the host in which to store the imported VMs. You can override the default behavior and preserve the MAC addresses on import. Click Import to import the appliance. Because disk images are large, the VMDK images that are included with virtual appliances are shipped in a compressed format that cannot be used directly by VMs.

So, the images are first unpacked and copied, which might take several minutes. You can use the VBoxManage import command to import an appliance. Select one or more VMs to export, and click Next. The Appliance Settings screen enables you to select the following settings:. Format: Selects the Open Virtualization Format value for the output files. File: Selects the location in which to store the exported files.

Write Manifest File: Enables you to include a manifest file in the exported archive file. Click Next to show the Virtual System Settings screen. You can edit settings for the virtual appliance. For example, you can change the name of the virtual appliance or add product information, such as vendor details or license text.

Click Export to begin the export process. Note that this operation might take several minutes. You can use the VBoxManage export command to export an appliance. Prepare for Oracle Cloud Infrastructure Integration. Section 1. Install the Extension Pack. Create a key pair. Upload the public key of the key pair from your client device to the cloud service. Create a cloud profile. The cloud profile contains resource identifiers for your cloud account, such as your user OCID, and details of your key pair.

Your API requests are signed with your private key, and Oracle Cloud Infrastructure uses the public key to verify the authenticity of the request. You must upload the public key to the Oracle Cloud Infrastructure Console. Optional Create a. The key pair is usually installed in the. Display the User Settings page. Click Profile , User Settings. The Add Public Key dialog is displayed. Choose Public Key File. This option enables you to browse to the public key file on your local hard disk.

A cloud profile is a text file that contains details of your key files and Oracle Cloud Identifier OCID resource identifiers for your cloud account, such as the following:.

Fingerprint of the public key. To obtain the fingerprint, you can use the openssl command:. Location of the private key on the client device. Specify the full path to the private key. Optional Passphrase for the private key. This is only required if the key is encrypted. Shown on the Oracle Cloud Infrastructure Console. Click Administration , Tenancy Details. Tenancy OCID. Compartment OCID.

Click Identity , Compartments. User OCID. Automatically, by using the Cloud Profile Manager. The Cloud Profile Manager is a component of Oracle VM VirtualBox that enables you to create, edit, and manage cloud profiles for your cloud service accounts. Automatically, by using the VBoxManage cloudprofile command. Manually, by creating a config file in your Oracle Cloud Infrastructure configuration directory.

This is the same file that is used by the Oracle Cloud Infrastructure command line interface. Oracle VM VirtualBox automatically uses the config file if no cloud profile file is present in your global configuration directory. Alternatively, you can import this file manually into the Cloud Profile Manager. This section describes how to use the Cloud Profile Manager to create a cloud profile. To create a cloud profile by importing settings from your Oracle Cloud Infrastructure configuration file.

Perform the following steps to create a new cloud profile automatically, using the Cloud Profile Manager:. Click the Add icon and specify a Name for the profile.

Click Properties and specify the following property values for the profile:. Some of these are settings for your Oracle Cloud Infrastructure account, which you can view from the Oracle Cloud Infrastructure Console.

Click Apply to save your changes. Perform the following steps to import an existing Oracle Cloud Infrastructure configuration file into the Cloud Profile Manager:. Ensure that a config file is present in your Oracle Cloud Infrastructure configuration directory. Click the Import icon to open a dialog that prompts you to import cloud profiles from external files. This action overwrites any cloud profiles that are in your Oracle VM VirtualBox global settings directory. Click Properties to show the cloud profile settings.

Create a new cloud instance from a custom image stored on Oracle Cloud Infrastructure. You can configure whether a cloud instance is created and started after the export process has completed. From the Format drop-down list, select Oracle Cloud Infrastructure.

In the Account drop-down list, select the cloud profile for your Oracle Cloud Infrastructure account.

The list after the Account field shows the profile settings for your cloud account. In the Machine Creation field, select an option to configure settings for a cloud instance created when you export to Oracle Cloud Infrastructure.

The options enable you to do one of the following:. Configure settings for the cloud instance after you have finished exporting the VM. Configure settings for the cloud instance before you start to export the VM. Optional Edit storage settings used for the exported virtual machine in Oracle Cloud Infrastructure. You can change the following settings:. Emulated mode is suitable for legacy OS images. Depending on the selection in the Machine Creation field, the Cloud Virtual Machine Settings screen may be displayed before or after export.

This screen enables you to configure settings for the cloud instance, such as Shape and Disk Size. Click Create. Depending on the Machine Creation setting, a cloud instance may be started after upload to Oracle Cloud Infrastructure is completed. Oracle Cloud Infrastructure provides the option to import a custom Linux image. Before an Oracle VM VirtualBox image can be exported to Oracle Cloud Infrastructure, the custom image needs to be prepared to ensure that instances launched from the custom image can boot correctly and that network connections will work.

The following list shows some tasks to consider when preparing an Oracle Linux VM for export:. Use DHCP for network addresses.

Do not specify a MAC address. Disable persistent network device naming rules. This means that the Oracle Cloud Infrastructure instance will use the same network device names as the VM. Add net. Disable any udev rules for network device naming. For example, if an automated udev rule exists for net-persistence :.

Enable the serial console. This enables you to troubleshoot the instance when it is running on Oracle Cloud Infrastructure. Remove the resume setting from the kernel parameters. This setting slows down boot time significantly. This configures use of the serial console instead of a graphical terminal.

This configures the serial connection. This adds the serial console to the Linux kernel boot parameters. To verify the changes, reboot the machine and run the dmesg command to look for the updated kernel parameters. Enable paravirtualized device support. You do this by adding the virtio drivers to the initrd for the VM.

This procedure works only on machines with a Linux kernel of version 3. Check that the VM is running a supported kernel:. Use the dracut tool to rebuild initrd. Add the qemu module, as follows:. Verify that the virtio drivers are now present in initrd. For more information about importing a custom Linux image into Oracle Cloud Infrastructure, see also:.

In the Source drop-down list, select Oracle Cloud Infrastructure. Choose the required cloud instance from the list in the Machines field.

Click Import to import the instance from Oracle Cloud Infrastructure. The following describes the sequence of events when you import an instance from Oracle Cloud Infrastructure. The custom image is exported to an Oracle Cloud Infrastructure object and is stored using Object Storage in the bucket specified by the user. The Oracle Cloud Infrastructure object is downloaded to the local host. Using a custom image means that you can quickly create cloud instances without having to upload your image to the cloud service every time.

Perform the following steps to create a new cloud instance on Oracle Cloud Infrastructure:. From the Destination drop-down list, select Oracle Cloud Infrastructure. In the Images list, select from the custom images available on Oracle Cloud Infrastructure. For example, you can edit the Disk Size and Shape used for the VM instance and the networking configuration.

Click Create to create the new cloud instance. Monitor the instance creation process by using the Oracle Cloud Infrastructure Console. You can also use the VBoxManage cloud instance command to create and manage instances on a cloud service. This section includes some examples of how VBoxManage commands can be used to integrate with Oracle Cloud Infrastructure and perform common cloud operations. For more details about the available commands for cloud operations, see Section 8. The Global Settings dialog can be displayed using the File menu, by clicking the Preferences item.

This dialog offers a selection of settings, most of which apply to all virtual machines of the current user. The Extensions option applies to the entire system. Enables the user to specify the Host key. The Host key is also used to trigger certain VM actions, see Section 1. Enables the user to specify various settings for Automatic Updates. Enables the user to specify the GUI language. Enables the user to specify the screen resolution, and its width and height.

A default scale factor can be specified for all guest screens. Enables the user to configure the details of NAT networks. See Section 6. Enables the user to list and manage the installed extension packages. As briefly mentioned in Section 1. For example, you can start a virtual machine with the VirtualBox Manager window and then stop it from the command line. This is the VirtualBox Manager, a graphical user interface that uses the Qt toolkit.

This interface is described throughout this manual. While this is the simplest and easiest front-end to use, some of the more advanced Oracle VM VirtualBox features are not included. As opposed to the other graphical interfaces, the headless front-end requires no graphics support.

This is useful, for example, if you want to host your virtual machines on a headless Linux server that has no X Window system installed. If the above front-ends still do not satisfy your particular needs, it is possible to create yet another front-end to the complex virtualization engine that is the core of Oracle VM VirtualBox, as the Oracle VM VirtualBox core neatly exposes all of its features in a clean API.

Oracle VM VirtualBox provides a soft keyboard that enables you to input keyboard characters on the guest. A soft keyboard is an on-screen keyboard that can be used as an alternative to a physical keyboard. For best results, ensure that the keyboard layout configured on the guest OS matches the keyboard layout used by the soft keyboard. Oracle VM VirtualBox does not do this automatically.

When the physical keyboard on the host is not the same as the keyboard layout configured on the guest. For example, if the guest is configured to use an international keyboard, but the host keyboard is US English. To send special key combinations to the guest. Note that some common key combinations are also available in the Input , Keyboard menu of the guest VM window. When using nested virtualization, the soft keyboard provides a method of sending key presses to a guest.

By default, the soft keyboard includes some common international keyboard layouts. You can copy and modify these to meet your own requirements. The name of the current keyboard layout is displayed in the task bar of the soft keyboard window. This is the previous keyboard layout that was used.

Click the Layout List icon in the task bar of the soft keyboard window. The Layout List window is displayed. Select the required keyboard layout from the entries in the Layout List window. The keyboard display graphic is updated to show the available input keys.

Modifier keys such as Shift, Ctrl, and Alt are available on the soft keyboard. Click once to select the modifier key, click twice to lock the modifier key. The Reset the Keyboard and Release All Keys icon can be used to release all pressed modifier keys, both on the host and the guest.

To change the look of the soft keyboard, click the Settings icon in the task bar. You can change colors used in the keyboard graphic, and can hide or show sections of the keyboard, such as the NumPad or multimedia keys.

You can use one of the supplied default keyboard layouts as the starting point to create a custom keyboard layout. To permananently save a custom keyboard layout, you must save it to file. Otherwise, any changes you make are discarded when you close down the Soft Keyboard window.

Custom keyboard layouts that you save are stored as an XML file on the host, in the keyboardLayouts folder in the global configuration data directory. Highlight the required layout and click the Copy the Selected Layout icon.

A new layout entry with a name suffix of -Copy is created. Edit keys in the new layout. Click on the key that you want to edit and enter new key captions in the Captions fields. Optional Save the layout to file. This means that your custom keyboard layout will be available for future use. Any custom layouts that you create can later be removed from the Layout List, by highlighting and clicking the Delete the Selected Layout icon.

Oracle® VM VirtualBox®.Please wait while your request is being verified…

 

The manual provides information on how to install Oracle VM VirtualBox and use it to create and configure virtual machines. It is assumed that readers are familiar with Web technologies and have a general understanding of Windows and UNIX platforms. Oracle customers that have purchased support have access to electronic support through My Oracle Support. Oracle is fully committed to diversity and inclusion.

Oracle recognizes the influence of ethnic and cultural values and is working to remove language from our products and documentation that might be considered insensitive.

While doing so, we are also mindful of the necessity to maintain compatibility with our customers’ existing technologies and the need to ensure continuity of service as Oracle’s offerings and industry standards evolve. Because of these technical constraints, our effort to remove insensitive terms is an ongoing, long-term process. Oracle VM VirtualBox is a cross-platform virtualization application.

What does that mean? Secondly, it extends the capabilities of your existing computer so that it can run multiple OSes, inside multiple virtual machines, at the same time. As an example, you can run Windows and Linux on your Mac, run Windows Server on your Linux server, run Linux on your Windows PC, and so on, all alongside your existing applications.

You can install and run as many virtual machines as you like. The only practical limits are disk space and memory. Oracle VM VirtualBox is deceptively simple yet also very powerful. It can run everywhere from small embedded systems or desktop class machines all the way up to datacenter deployments and even Cloud environments.

Figure 1. In this User Manual, we will begin simply with a quick introduction to virtualization and how to get your first virtual machine running with the easy-to-use Oracle VM VirtualBox graphical user interface. Subsequent chapters will go into much more detail covering more powerful tools and features, but fortunately, it is not necessary to read the entire User Manual before you can use Oracle VM VirtualBox. The techniques and features that Oracle VM VirtualBox provides are useful in the following scenarios:.

Running multiple operating systems simultaneously. This way, you can run software written for one OS on another, such as Windows software on Linux or a Mac, without having to reboot to use it. Easier software installations. Software vendors can use virtual machines to ship entire software configurations. For example, installing a complete mail server solution on a real machine can be a tedious task.

With Oracle VM VirtualBox, such a complex setup, often called an appliance , can be packed into a virtual machine. Installing and running a mail server becomes as easy as importing such an appliance into Oracle VM VirtualBox. Testing and disaster recovery. Once installed, a virtual machine and its virtual hard disks can be considered a container that can be arbitrarily frozen, woken up, copied, backed up, and transported between hosts. On top of that, with the use of another Oracle VM VirtualBox feature called snapshots , one can save a particular state of a virtual machine and revert back to that state, if necessary.

This way, one can freely experiment with a computing environment. If something goes wrong, such as problems after installing software or infecting the guest with a virus, you can easily switch back to a previous snapshot and avoid the need of frequent backups and restores.

Any number of snapshots can be created, allowing you to travel back and forward in virtual machine time. You can delete snapshots while a VM is running to reclaim disk space.

Infrastructure consolidation. Virtualization can significantly reduce hardware and electricity costs. Most of the time, computers today only use a fraction of their potential power and run with low average system loads. A lot of hardware resources as well as electricity is thereby wasted. So, instead of running many such physical computers that are only partially used, one can pack many virtual machines onto a few powerful hosts and balance the loads between them.

When dealing with virtualization, and also for understanding the following chapters of this documentation, it helps to acquaint oneself with a bit of crucial terminology, especially the following terms:.

Host operating system host OS. See Section 1. There may be platform-specific differences which we will point out where appropriate. Guest operating system guest OS. This is the OS that is running inside the virtual machine. But to achieve near-native performance of the guest code on your machine, we had to go through a lot of optimizations that are specific to certain OSes.

So while your favorite OS may run as a guest, we officially support and optimize for a select few, which include the most common OSes. See Section 3. Virtual machine VM. In other words, you run your guest OS in a VM. Normally, a VM is shown as a window on your computer’s desktop. Depending on which of the various frontends of Oracle VM VirtualBox you use, the VM might be shown in full screen mode or remotely on another computer. Some parameters describe hardware settings, such as the amount of memory and number of CPUs assigned.

Other parameters describe the state information, such as whether the VM is running or saved. See Chapter 8, VBoxManage. Guest Additions. This refers to special software packages which are shipped with Oracle VM VirtualBox but designed to be installed inside a VM to improve performance of the guest OS and to add extra features.

See Chapter 4, Guest Additions. Oracle VM VirtualBox runs on a large number of bit host operating systems. Oracle VM VirtualBox is a so-called hosted hypervisor, sometimes referred to as a type 2 hypervisor.

Whereas a bare-metal or type 1 hypervisor would run directly on the hardware, Oracle VM VirtualBox requires an existing OS to be installed. It can thus run alongside existing applications on that host. To a very large degree, Oracle VM VirtualBox is functionally identical on all of the host platforms, and the same file and image formats are used.

This enables you to run virtual machines created on one host on another host with a different host OS. For example, you can create a virtual machine on Windows and then run it under Linux. In addition, virtual machines can easily be imported and exported using the Open Virtualization Format OVF , an industry standard created for this purpose.

You can even import OVFs that were created with a different virtualization software. For users of Oracle Cloud Infrastructure the functionality extends to exporting and importing virtual machines to and from the cloud. This simplifies development of applications and deployment to the production environment.

Guest Additions: shared folders, seamless windows, 3D virtualization. The Oracle VM VirtualBox Guest Additions are software packages which can be installed inside of supported guest systems to improve their performance and to provide additional integration and communication with the host system. After installing the Guest Additions, a virtual machine will support automatic adjustment of video resolutions, seamless windows, accelerated 3D graphics and more.

In particular, Guest Additions provide for shared folders , which let you access files on the host system from within a guest machine. See Section 4. Great hardware support. Guest multiprocessing SMP. USB device support. Oracle VM VirtualBox implements a virtual USB controller and enables you to connect arbitrary USB devices to your virtual machines without having to install device-specific drivers on the host.

USB support is not limited to certain device categories. Hardware compatibility. Oracle VM VirtualBox virtualizes a vast array of virtual devices, among them many devices that are typically provided by other virtualization platforms. This enables easy cloning of disk images from real machines and importing of third-party virtual machines into Oracle VM VirtualBox. Full ACPI support. This enables easy cloning of disk images from real machines or third-party virtual machines into Oracle VM VirtualBox.

For mobile systems running on battery, the guest can thus enable energy saving and notify the user of the remaining power, for example in full screen modes. Multiscreen resolutions. Oracle VM VirtualBox virtual machines support screen resolutions many times that of a physical screen, allowing them to be spread over a large number of screens attached to the host system. Built-in iSCSI support. This unique feature enables you to connect a virtual machine directly to an iSCSI storage server without going through the host system.

The VM accesses the iSCSI target directly without the extra overhead that is required for virtualizing hard disks in container files. See Section 5. PXE Network boot. Multigeneration branched snapshots. Oracle VM VirtualBox can save arbitrary snapshots of the state of the virtual machine. You can go back in time and revert the virtual machine to any such snapshot and start an alternative VM configuration from there, effectively creating a whole snapshot tree.

You can create and delete snapshots while the virtual machine is running. VM groups. Oracle VM VirtualBox provides a groups feature that enables the user to organize and control virtual machines collectively, as well as individually.

In addition to basic groups, it is also possible for any VM to be in more than one group, and for groups to be nested in a hierarchy. This means you can have groups of groups.

All your programs will still be open, and your computer resumes operation. Saving the state of a virtual machine is thus in some ways similar to suspending a laptop computer by closing its lid. Send the shutdown signal. This will send an ACPI shutdown signal to the virtual machine, which has the same effect as if you had pressed the power button on a real computer.

This should trigger a proper shutdown mechanism from within the VM. Power off the machine: With this option, Oracle VM VirtualBox also stops running the virtual machine, but without saving its state.

This is equivalent to pulling the power plug on a real computer without shutting it down properly. If you start the machine again after powering it off, your OS will have to reboot completely and may begin a lengthy check of its virtual system disks. As a result, this should not normally be done, since it can potentially cause data loss or an inconsistent state of the guest system on disk.

As an exception, if your virtual machine has any snapshots, see Section 1. In that case, powering off the machine will not disrupt its state, but any changes made since that snapshot was taken will be lost. The Discard button in the VirtualBox Manager window discards a virtual machine’s saved state. This has the same effect as powering it off, and the same warnings apply. VM groups enable the user to create ad hoc groups of VMs, and to manage and perform functions on them collectively, as well as individually.

Select multiple VMs and select Group from the right-click menu. This command creates a group “TestGroup” and attaches the VM “vm01” to that group. Detach a VM from the group, and delete the group if empty. For example:. This command detaches all groups from the VM “vm01” and deletes the empty group.

This command creates the groups “TestGroup” and “TestGroup2”, if they do not exist, and attaches the VM “vm01” to both of them. With snapshots, you can save a particular state of a virtual machine for later use. At any later time, you can revert to that state, even though you may have changed the VM considerably since then.

A snapshot of a virtual machine is thus similar to a machine in Saved state, but there can be many of them, and these saved states are preserved. To see the snapshots of a virtual machine, click on the machine name in VirtualBox Manager. Then click the List icon next to the machine name, and select Snapshots. Until you take a snapshot of the machine, the list of snapshots will be empty except for the Current State item, which represents the “now” point in the lifetime of the virtual machine.

Take a snapshot. This makes a copy of the machine’s current state, to which you can go back at any given time later. The snapshots window is shown. Do one of the following:. Click the Take icon.

Right-click on the Current State item in the list and select Take. In either case, a window is displayed prompting you for a snapshot name. This name is purely for reference purposes to help you remember the state of the snapshot. For example, a useful name would be “Fresh installation from scratch, no Guest Additions”, or “Service Pack 3 just installed”.

You can also add a longer text in the Description field. Your new snapshot will then appear in the snapshots list. Underneath your new snapshot, you will see an item called Current State , signifying that the current state of your VM is a variation based on the snapshot you took earlier. If you later take another snapshot, you will see that they are displayed in sequence, and that each subsequent snapshot is derived from an earlier one. Oracle VM VirtualBox imposes no limits on the number of snapshots you can take.

The only practical limitation is disk space on your host. Each snapshot stores the state of the virtual machine and thus occupies some disk space. Restore a snapshot. In the list of snapshots, right-click on any snapshot you have taken and select Restore. By restoring a snapshot, you go back or forward in time. The current state of the machine is lost, and the machine is restored to the exact state it was in when the snapshot was taken. Restoring a snapshot will affect the virtual hard drives that are connected to your VM, as the entire state of the virtual hard drive will be reverted as well.

This means also that all files that have been created since the snapshot and all other file changes will be lost. In order to prevent such data loss while still making use of the snapshot feature, it is possible to add a second hard drive in write-through mode using the VBoxManage interface and use it to store your data. As write-through hard drives are not included in snapshots, they remain unaltered when a machine is reverted. To avoid losing the current state when restoring a snapshot, you can create a new snapshot before the restore operation.

By restoring an earlier snapshot and taking more snapshots from there, it is even possible to create a kind of alternate reality and to switch between these different histories of the virtual machine. This can result in a whole tree of virtual machine snapshots, as shown in the screenshot above.

Delete a snapshot. This does not affect the state of the virtual machine, but only releases the files on disk that Oracle VM VirtualBox used to store the snapshot data, thus freeing disk space. To delete a snapshot, right-click on the snapshot name in the snapshots tree and select Delete.

Snapshots can be deleted even while a machine is running. Whereas taking and restoring snapshots are fairly quick operations, deleting a snapshot can take a considerable amount of time since large amounts of data may need to be copied between several disk image files. Temporary disk files may also need large amounts of disk space while the operation is in progress.

There are some situations which cannot be handled while a VM is running, and you will get an appropriate message that you need to perform this snapshot deletion when the VM is shut down. Think of a snapshot as a point in time that you have preserved. More formally, a snapshot consists of the following:. The snapshot contains a complete copy of the VM settings, including the hardware configuration, so that when you restore a snapshot, the VM settings are restored as well.

For example, if you changed the hard disk configuration or the VM’s system settings, that change is undone when you restore the snapshot. The copy of the settings is stored in the machine configuration, an XML text file, and thus occupies very little space. The complete state of all the virtual disks attached to the machine is preserved.

Going back to a snapshot means that all changes that had been made to the machine’s disks, file by file and bit by bit, will be undone as well. Files that were since created will disappear, files that were deleted will be restored, changes to files will be reverted. Strictly speaking, this is only true for virtual hard disks in “normal” mode.

You can configure disks to behave differently with snapshots, see Section 5. In technical terms, it is not the virtual disk itself that is restored when a snapshot is restored. Instead, when a snapshot is taken, Oracle VM VirtualBox creates differencing images which contain only the changes since the snapshot were taken.

When the snapshot is restored, Oracle VM VirtualBox throws away that differencing image, thus going back to the previous state. This is both faster and uses less disk space. For the details, which can be complex, see Section 5. Creating the differencing image as such does not occupy much space on the host disk initially, since the differencing image will initially be empty and grow dynamically later with each write operation to the disk.

The longer you use the machine after having created the snapshot, however, the more the differencing image will grow in size. If you took a snapshot while the machine was running, the memory state of the machine is also saved in the snapshot. This is in the same way that memory can be saved when you close a VM window. When you restore such a snapshot, execution resumes at exactly the point when the snapshot was taken.

The memory state file can be as large as the memory size of the VM and will therefore occupy considerable disk space. When you select a virtual machine from the list in the VirtualBox Manager window, you will see a summary of that machine’s settings on the right.

Clicking on Settings displays a window, where you can configure many of the properties of the selected VM. But be careful when changing VM settings. It is possible to change all VM settings after installing a guest OS, but certain changes might prevent a guest OS from functioning correctly if done after installation.

This is because the Settings dialog enables you to change fundamental characteristics of the virtual machine that is created for your guest OS. For example, the guest OS may not perform well if half of its memory is taken away. As a result, if the Settings button is disabled, shut down the current VM first.

Oracle VM VirtualBox provides a wide range of parameters that can be changed for a virtual machine. The various settings that can be changed in the Settings window are described in detail in Chapter 3, Configuring Virtual Machines. Even more parameters are available when using the VBoxManage command line interface. Removing a VM. The confirmation dialog enables you to specify whether to only remove the VM from the list of machines or to remove the files associated with the VM.

Note that the Remove menu item is disabled while a VM is running. Moving a VM. Note that the Move menu item is disabled while a VM is running. You can create a full copy or a linked copy of an existing VM. This copy is called a clone. The Clone Virtual Machine wizard guides you through the cloning process. Start the wizard by clicking Clone in the right-click menu of the VirtualBox Manager’s machine list or in the Snapshots view of the selected VM. Specify a new Name for the clone.

You can choose a Path for the cloned virtual machine, otherwise Oracle VM VirtualBox uses the default machines folder. The Clone Type option specifies whether to create a clone linked to the source VM or to create a fully independent clone:. Full Clone: Copies all dependent disk images to the new VM folder.

A full clone can operate fully without the source VM. Linked Clone: Creates new differencing disk images based on the source VM disk images.

The Snapshots option specifies whether to create a clone of the current machine state only or of everything. Everything: Clones the current machine state and all its snapshots.

Current Machine State and All Children:. Clones a VM snapshot and all its child snapshots. This is the default setting. This is the best option when both the source VM and the cloned VM must operate on the same network. The duration of the clone operation depends on the size and number of attached disk images. In addition, the clone operation saves all the differencing disk images of a snapshot. Note that the Clone menu item is disabled while a machine is running.

Oracle VM VirtualBox can import and export virtual machines in the following formats:. This is the industry-standard format. Cloud service formats. Export to and import from cloud services such as Oracle Cloud Infrastructure is supported. OVF is a cross-platform standard supported by many virtualization products which enables the creation of ready-made virtual machines that can then be imported into a hypervisor such as Oracle VM VirtualBox. Using OVF enables packaging of virtual appliances.

These are disk images, together with configuration settings that can be distributed easily. This way one can offer complete ready-to-use software packages, including OSes with applications, that need no configuration or installation except for importing into Oracle VM VirtualBox.

In particular, no guarantee is made that Oracle VM VirtualBox supports all appliances created by other virtualization software. For a list of known limitations, see Chapter 14, Known Limitations. They can come in several files, as one or several disk images, typically in the widely-used VMDK format.

They also include a textual description file in an XML dialect with an. These files must then reside in the same directory for Oracle VM VirtualBox to be able to import them. Alternatively, the above files can be packed together into a single archive file, typically with an. OVF cannot describe snapshots that were taken for a virtual machine. As a result, when you export a virtual machine that has snapshots, only the current state of the machine will be exported. The disk images in the export will have a flattened state identical to the current state of the virtual machine.

From the file dialog, go to the file with either the. Click Import to open the Appliance Settings screen. You can change this behavior by using the Primary Group setting for the VM. Base Folder: Specifies the directory on the host in which to store the imported VMs. You can override the default behavior and preserve the MAC addresses on import. Click Import to import the appliance. Because disk images are large, the VMDK images that are included with virtual appliances are shipped in a compressed format that cannot be used directly by VMs.

So, the images are first unpacked and copied, which might take several minutes. You can use the VBoxManage import command to import an appliance. Select one or more VMs to export, and click Next. The Appliance Settings screen enables you to select the following settings:.

Format: Selects the Open Virtualization Format value for the output files. File: Selects the location in which to store the exported files. Write Manifest File: Enables you to include a manifest file in the exported archive file.

Click Next to show the Virtual System Settings screen. You can edit settings for the virtual appliance. For example, you can change the name of the virtual appliance or add product information, such as vendor details or license text. Click Export to begin the export process. Note that this operation might take several minutes. You can use the VBoxManage export command to export an appliance. Prepare for Oracle Cloud Infrastructure Integration. Section 1.

Automatically, by using the VBoxManage cloudprofile command. Manually, by creating a config file in your Oracle Cloud Infrastructure configuration directory.

This is the same file that is used by the Oracle Cloud Infrastructure command line interface. Oracle VM VirtualBox automatically uses the config file if no cloud profile file is present in your global configuration directory.

Alternatively, you can import this file manually into the Cloud Profile Manager. This section describes how to use the Cloud Profile Manager to create a cloud profile. To create a cloud profile by importing settings from your Oracle Cloud Infrastructure configuration file. Perform the following steps to create a new cloud profile automatically, using the Cloud Profile Manager:.

Click the Add icon and specify a Name for the profile. Click Properties and specify the following property values for the profile:. Some of these are settings for your Oracle Cloud Infrastructure account, which you can view from the Oracle Cloud Infrastructure Console. Click Apply to save your changes. Perform the following steps to import an existing Oracle Cloud Infrastructure configuration file into the Cloud Profile Manager:.

The options enable you to do one of the following:. Configure settings for the cloud instance after you have finished exporting the VM.

Configure settings for the cloud instance before you start to export the VM. Optional Edit storage settings used for the exported virtual machine in Oracle Cloud Infrastructure. You can change the following settings:.

Emulated mode is suitable for legacy OS images. Depending on the selection in the Machine Creation field, the Cloud Virtual Machine Settings screen may be displayed before or after export.

This screen enables you to configure settings for the cloud instance, such as Shape and Disk Size. Click Create. Depending on the Machine Creation setting, a cloud instance may be started after upload to Oracle Cloud Infrastructure is completed. Oracle Cloud Infrastructure provides the option to import a custom Linux image.

Before an Oracle VM VirtualBox image can be exported to Oracle Cloud Infrastructure, the custom image needs to be prepared to ensure that instances launched from the custom image can boot correctly and that network connections will work. The following list shows some tasks to consider when preparing an Oracle Linux VM for export:.

Use DHCP for network addresses. Do not specify a MAC address. Disable persistent network device naming rules. This means that the Oracle Cloud Infrastructure instance will use the same network device names as the VM.

Add net. Disable any udev rules for network device naming. For example, if an automated udev rule exists for net-persistence :. Enable the serial console.

This enables you to troubleshoot the instance when it is running on Oracle Cloud Infrastructure. Remove the resume setting from the kernel parameters. This setting slows down boot time significantly. This configures use of the serial console instead of a graphical terminal. This configures the serial connection. This adds the serial console to the Linux kernel boot parameters.

To verify the changes, reboot the machine and run the dmesg command to look for the updated kernel parameters. Enable paravirtualized device support. You do this by adding the virtio drivers to the initrd for the VM.

This procedure works only on machines with a Linux kernel of version 3. Check that the VM is running a supported kernel:.

Use the dracut tool to rebuild initrd. Add the qemu module, as follows:. Verify that the virtio drivers are now present in initrd. For more information about importing a custom Linux image into Oracle Cloud Infrastructure, see also:. In the Source drop-down list, select Oracle Cloud Infrastructure.
