This might help 32 bit guests, but not guests with 64 bit

AMD + 64 bit -> syscall.
Okay, I don't see a great option other than migrating the vendor_id string.
Otherwise, cross vendor migration will not work by default. Maybe
that's not a problem but if so, we really should change the default cpu
model to be much more aggressive about exposing host features.
