These tools make VM keyboard and mouse operations much more seamless. Most importantly, the Guest Additions suppress the second “guest” mouse pointer and make your host mouse pointer work directly in the guest. Some OSes expect certain key combinations to initiate certain procedures. The recipient of these keypresses depends on a number of factors, including the key combination itself.

Host OSes reserve certain key combinations for themselves. As the X server intercepts this combination, pressing it will usually restart your host graphical user interface and kill all running programs, including Oracle VM VirtualBox, in the process. If, instead, you want to send these key combinations to the guest OS in the virtual machine, you will need to use one of the following methods:.

Use the items in the Input , Keyboard menu of the virtual machine window. However, the latter setting affects only Linux guests or Oracle Solaris guests. This menu also includes an option for inserting the Host key combination. Use special key combinations with the Host key, which is normally the right Control key. This is a global setting for all virtual machines and can be found under File , Preferences , Input. A soft keyboard can be used to input key combinations in the guest. While a virtual machine is running, you can change removable media in the Devices menu of the VM’s window.

But as the Settings dialog is disabled while the VM is in the Running or Saved state, the Devices menu saves you from having to shut down and restart the VM every time you want to change media. Using the Devices menu, you can attach the host drive to the guest or select a floppy or DVD image, as described in Section 3.

You can resize the VM’s window while that VM is running. When you do, the window is scaled as follows:. If you have scaled mode enabled, then the virtual machine’s screen will be scaled to the size of the window. This can be useful if you have many machines running and want to have a look at one of them while it is running in the background.

Alternatively, it might be useful to enlarge a window if the VM’s output screen is very small, for example because you are running an old OS in it. The aspect ratio of the guest screen is preserved when resizing the window. To ignore the aspect ratio, press Shift during the resize operation. See Chapter 14, Known Limitations for additional remarks. If you have the Guest Additions installed and they support automatic resizing , the Guest Additions will automatically adjust the screen resolution of the guest OS.

For example, if you are running a Windows guest with a resolution of x pixels and you then resize the VM window to make it pixels wider, the Guest Additions will change the Windows display resolution to x Otherwise, if the window is bigger than the VM’s screen, the screen will be centered.

If it is smaller, then scroll bars will be added to the machine window. When you click on the Close button of your virtual machine window, at the top right of the window, just like you would close any other window on your system, Oracle VM VirtualBox asks you whether you want to save or power off the VM. Save the machine state: With this option, Oracle VM VirtualBox freezes the virtual machine by completely saving its state to your local disk.

When you start the VM again later, you will find that the VM continues exactly where it was left off.

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. Install the Extension Pack.

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. Last Step to Get Freeware. Email is required Please enter a valid email. Thanks for downloading our product.

Microsoft noted in a white paper on the Windows Biometric Framework that the proliferation of these proprietary stacks resulted in compatibility issues, compromised the quality and reliability of the system, and made servicing and maintenance more difficult.

By incorporating the core biometric functionality into the operating system, Microsoft aims to bring biometric device support on par with other classes of devices. A new Control Panel called Biometric Device Control Panel is included which provides an interface for deleting stored biometrics information, troubleshooting, and enabling or disabling the types of logins that are allowed using biometrics.

Biometrics configuration can also be configured using Group Policy settings. Alongside the workgroup system used by previous versions, Windows 7 adds a new ad hoc home networking system known as HomeGroup. The system uses a password to join computers into the group, and allows users’ libraries, along with individual files and folders, to be shared between multiple computers.

Only computers running Windows 7 to Windows 10 version can create or join a HomeGroup; [] [] however, users can make files and printers shared in a HomeGroup accessible to Windows XP and Windows Vista through a separate account, dedicated to sharing HomeGroup content, that uses traditional Windows sharing.

HomeGroup as a concept is very similar to a feature slated for Windows Vista, known as Castle , which would have made it possible to have an identification service for all members on the network, without a centralized server. HomeGroup is created in response to the need for a simple sharing model for inexperienced users who need to share files without wrestling with user accounts , Security descriptors and share permissions.

Under this model, either a certain file or folder was shared with anyone who connects to the network even unauthorized parties who are in range of the wireless network or was not shared at all. Windows 7 adds support for multiple firewall profiles.

The Windows Firewall in Windows Vista dynamically changes which network traffic is allowed or blocked based on the location of the computer based on which network it is connected to. This approach falls short if the computer is connected to more than one network at the same time as for a computer with both an Ethernet and a wireless interface.

In this case, Vista applies the profile that is more secure to all network connections. This is often not desirable; Windows 7 resolves this by being able to apply a separate firewall profile to each network connection.
