Live migration between different vendors isn't tested enough for us to
be confident in saying it works well. There has been some work done in
the area, but there can always be bugs or unimplemented features. If you
do try it, please share your experiences whether good or bad.
I think NPT support should get enabled for your VM if the migration does
succeed.

The Q6600 does not support EPT, right? If so, the Phenom will be faster
as it does support NPT.
