how do you recover an XP VM from Guru Meditation state?

[stuman]

I can only find "suggestions" to prevent it, but nothing that will work to recover it. And this only happens after the latest VirtualBox upgrade...

I'm running XP under vboxheadless, which may have something to do with it, but the memory requirements of the VM are small...only 512m...with several gig available on the host, which is Xubuntu 12.04 and the same thing happens under 14.02 (different hosts...same XP VM).

First, how do I get rid of the Guru Meditation mode? Most options for power down, restart etc are grayed out.

Second, how do I prevent it in the future? I use the XP VM to monitor my solar system...and I use the same system to access a client, so it is really important that it NOT happen on that XP VM.
