so to be honest...what really spawned this... I put all my VMs on an NFS
share. I've got an F11 VM I run...but on my x86_64 host - starting the
F11 VM (its an i386 VM) fails to start. If I run F11 x86_64 it works
fine. I' really just trying to simplify things and standards on one type
of VM ;) Yes, I don't have any issues with CentOS guest VMs being i386
and running on the x86_64 host - works fine...
