Yeah @Boris - it really seems to be an issue bound to the Merom/Penryn
processor generation.
I asked Andreas to check through some kernels and qemu versions so that
we maybe eventually can consider bisecting something. But that will take
a bit of time.
Of course everyone able to spend some time can consider checking a few
kernels of [1] as well (probably the easiest test to begin with).
Still if there is an x86-microarchitecture expert out there that say "ah
penryn, I know we added/dropped ... " please speak up :-)

After upgrade, all KVM guests are in a default pause state. Even after
forcing them off via virsh, and restarting them the guests are paused.
These Guests are not nested.
A lot of diganostic information are outlined in the previous bug
report link provided. The solution mentioned in previous report had
been allegedly integrated into the downstream updates.
