Fixing the VirtualBox clibboard

VirtualBox has a nice bi-directional clipboard feature. Unfortunately it dies from time to time. My usual rememdy is rebooting. But now I have a better solution, thanks to this superuser.com entry.

The problem is with VBoxClient. The fix is to kill the VBoxClient services, and restart them, thus:

killall VBoxClient/usr/bin/VBoxClient --clipboard
