Brandon,

Mario Lobo and I have been working on this in the background and we found
that multiple cpu support in Virtualbox appears broken.  Any VM with more
than 1 CPU will freeze.  

Mario was also able to find that using unganged memory also confuses
Virtualbox.  He enabled that in his motherboard and Virtualbox became more
stable.

I have been able to run 6 VM's at the same time, with compositing enabled,
and 3D acceleration in the VM as well, all with 1 CPU per VM only.

Sincerely,
Rusty Nejdl
