I found a write up on scripts that detect and unload/load the kvm and
kvm-intel modules.  In fact, the very one that you referenced.  And I had
already gathered that one probably cannot run both a kvm and a vb hypervisor
on the same host at the same time.  I was wondering if there was any other
issues respecting having both of them installed on the same host at the same
time even if only one, or neither, is running?

A supplemental question:  Is there any way to convert a VB guest image into a
KVM guest image?  The VM image in question is MicroSoft's IE6 development
image for MS-XPproSP3.  We have a government mandated program that is written
in J# and the last OS to support that is XP.  I have to get some sort of
virtualised XP guest running and as the transferable licenses for that OS are
somewhat scarce I thought I might try and get the legal VM version running. 
However, I would prefer to stick with KVM if at all possible.
