We use cookies to make your experience of our websites better. By using and further navigating this website you accept this. Copy and paste. Copy text and files between the virtual machine and the host PC. Drag and drop. Drag and drop files between a Windows host PC and a Windows virtual machine. Multiple networking options.

Virtual machines can share or obtain new IP addresses or be isolated from the network and host. Run a wide variety of virtual machines containing and bit operating systems simultaneously on the same physical PC.

Adjustable memory. 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. Paste Public Keys. This option enables you to paste the contents of the public key file into the window in the dialog box.

Click Add to upload the public key. 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.
