Sometimes, the shared clipboard works just fine for a while, and then suddenly you no longer have access to the host clipboard on the VM. If you didn’t use the VM for a while and copy/paste causes problems, you should reinstall the Guest Additions. This is often the case if you updated the VirtualBox but not the Guest Additions on the VM. One possible cause is that you are working with outdated Guest Additions. In practice, I found that copy/paste often isn’t working properly. Shared clipboard in VM settings Update Guest Additions ^ The VM settings can be opened in the VirtualBox Manager or through the key combination HOST + S. You also can enable copy/paste in the VM’s General settings on the Advanced Tab.
I usually enable bidirectional shared clipboard when I am working with multiple virtual machines, so I can copy and paste from VM to VM. If you are testing software that you don’t trust, you might want to only enable Host To Guest. After you reboot the virtual machine, you can enable copy/paste on the Devices menu of the VM under Shared Clipboard.
To install the Guest Additions launch VBoxWindowsAdditions.exe. In fact, Oracle have set VirtualBox up in such a way as to allow you to press any of the function keys from F1 through F12 and with the host key, will be passed as CTRL+ALT+Fn to the guest.The Guest Additions CD image should be mapped to drive D. The F1 through F8 keys work in a similar way if you press them after the Host key. On my Linux host OS, the host key is the right side CTRL key.īy pressing that, holding it down and pressing BackSpace, for example, I can reset the X system in the guest (Linux) OS. Simple, since very early versions of VirtualBox (around 1.3.7 or 1.3.8) the Host (Virtual) key is a good substitute for CTRL+ALT and can be used for other special key combinations. Normally, those keys would be grabbed and actioned by the host OS rather than being passed to the guest. As standard, VirtualBox has a menu option (machine->Insert CTRL+ALT+Backspace or Insert CTRL+ALT+DEL) which is fine if you need these key combinations sending to the guest and not grabbed by the host, however, how can you send CTRL+ALT+F1 through CTRL+ALT+F8 to a Linux guest OS to get it to startup one of its virtual consoles?
