Haha. That's cool. :) I'm pretty sure I never needed to 'hack' anything 
to allow it. I can't find an un-updated cluster to test it on.

The good news is, I can create the image and configure the 
vm-config-file. Works fine, just not for a normal user. It performes 
fine as well, although I would recommend only raw images. I think I 
remember issues with qcow2 and snapshots.
