after some research, I think this is the issue:
the invocation of qemu on this system is:
qemu-system-x86_64 -enable-kvm -name instance-0000107c -S -machine
and I believe the 'invtsc' which comes from the cpu flag nonstop_tsc
on this X5650 is incorrect(?).
this is discussed here:
this also affects 'suspend' (same error) fwiw.
So, anyone else run into this, and if so, uh, what did you do about it?
