To check VirtualBox version from command line interface;. Once you have confirmed the version of the currently installed VirtualBox, navigate to the VirtualBox downloads page and grab the extension pack installer. You can simply run the command below to download the extension pack. Replace the value of VER accordingly. VirtualBox extension pack can be installed directly from VirtualBox main window or from the terminal by using the VBoxManage command.
To install the extension pack using vboxmanage command, you first need to uninstall the old version if any is installed. Once the installation is done, then run the command below to install the extension pack you just downloaded. If the older version of extension pack is installed, select it and click on the icon with x to detach it. Next, click the icon with plus sign to add the downloaded extension package.
Once you select the package, you will be prompted on installation. Click install , accept the EULA and proceed to complete the installation. If you encounter the error;. The port can be changed either in the Display settings of the graphical user interface or with the --vrdeport option of the VBoxManage modifyvm command. You can specify a comma-separated list of ports or ranges of ports.
Use a dash between two port numbers to specify a range. The VRDP server will bind to one of the available ports from the specified list. For example, VBoxManage modifyvm VM-name --vrdeport , configures the server to bind to one of the ports , , , or See Section 8. For this to work, you must specify the IP address of your host system, not of the virtual machine, as the server address to connect to.
You must also specify the port number that the VRDP server is using. Enter mstsc to start the program. If you use the Run dialog, you can enter options directly.
For example:. Replace 1. IPv6 addresses must be enclosed in square brackets to specify a port. For example: mstsc [fe] When connecting to localhost in order to test the connection, the addresses localhost and Instead, the address On other systems, you can use the standard open source rdesktop program. See Section 7. With rdesktop , use a command line such as the following:.
The -a 16 option requests a color depth of 16 bits per pixel, which we recommend. For best performance, after installation of the guest operating system, you should set its display color depth to the same value.
The -N option enables use of the NumPad keys. This application is included with some Linux distributions, such as Debian and Ubuntu. A typical command line is as follows:. See the Sun Ray documentation for details.
While any VM started from the VirtualBox Manager is capable of running virtual machines remotely, it is not convenient to have to run the full GUI if you never want to have VMs displayed locally in the first place. In particular, if you are running server hardware whose only purpose is to host VMs, and all your VMs are supposed to run remotely over VRDP, then it is pointless to have a graphical user interface on the server at all.
This is inconvenient if you would rather not have the X Window system on your server at all. For backwards compatibility, the Oracle VM VirtualBox installation still includes an executable with that name. To start a virtual machine with VBoxHeadless , you have the following options:.
Use the VBoxManage command, as follows:. Use the VBoxHeadless command, as follows:. This way of starting the VM helps troubleshooting problems reported by VBoxManage startvm , because you can sometimes see more detailed error messages, especially for early failures before the VM execution is started.
In normal situations VBoxManage startvm is preferred, since it runs the VM directly as a background process which has to be done explicitly when directly starting with VBoxHeadless. The full documentation of the command is in Section 7. You can override the VM's setting using --vrde command line parameter. The following instructions describe how to create a virtual machine on a headless server over a network connection. This example creates a virtual machine, establishes an RDP connection and installs a guest operating system.
All of these tasks are done without having to touch the headless server. You need the following prerequisites:. Oracle VM VirtualBox on a server machine with a supported host operating system. The procedures assume a Linux server is used. An ISO file accessible from the server, containing the installation data for the guest operating system to install.
Windows XP is used in the example. A terminal connection to that host through which you can access a command line, such as ssh. An RDP viewer on the remote client. Note that on the server machine, since we will only use the headless server, Qt and the X Window system are not required.
If you do not specify --register , you will have to manually use the registervm command later. You do not need to specify --ostype , but doing so selects some sensible default values for certain VM parameters.
For example, the RAM size and the type of the virtual network device. To get a complete list of supported operating systems you can use the following command:. Make sure the settings for the VM are appropriate for the guest operating system that we will install. Create a virtual hard disk for the VM. For example, to create a 10 GB virtual hard disk:.
Attach the ISO file that contains the operating system installation that you want to install later to the virtual machine. This is done so that the VM can boot from it. Start the virtual machine using the VBoxHeadless command:. If the configuration steps worked, you should see a copyright notice.
If you are returned to the command line, then something did not work correctly. On the client machine, start the RDP viewer and connect to the server.
The installation routine of your guest operating system should be displayed in the RDP viewer. This enables running of virtual machines on an Oracle VM VirtualBox host that acts as a server, where a client can connect from elsewhere that needs only a network adapter and a display capable of running an RDP viewer. See Section 3. All you have to do is specify Remote, or Any, when setting up these rules.
Some versions of uttsc , a client tailored for the use with Sun Ray thin clients, also support accessing remote USB devices. See Section Furthermore it is advisable to disable automatic loading of any host driver on the remote host which might work on USB devices to ensure that the devices are accessible by the RDP client. If the setup was properly done on the remote host, plug and unplug events are visible in the VBox.
Experimental support for PCI passthrough on Linux hosts. See PCI Passthrough. Disk image encryption with AES algorithm. See Encryption of Disk Images.
Oracle VM VirtualBox extension packages have a. To install an extension, simply double-click on the package file and a Network Operations Manager window is shown to guide you through the required steps. To view the extension packs that are currently installed, start the VirtualBox Manager, as shown in Section 1. From the File menu, select Preferences.
In the window that displays, go to the Extensions category. This shows you the extensions which are currently installed, and enables you to remove a package or add a new package.
