here it is, but note that there are few more machines running on this host. but they're almost idle in contrast to this windows one, so I hope it's not problem.

kvm_cr                       780       772
kvm_emulate_insn           46181     44982
kvm_entry                  55012     53867
kvm_exit                   55182     53884

It's emulating quite a bit.  Let's see why.

- install udis86 and udis86-devel
- build and install git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git - run trace-cmd record -e kvm -b 100000 -P pid1 -P pid2, ctrl-C after a few seconds (pid1/pid2 are thread ids from 'info cpus' of the bad guest, plus the pid of the qemu process itself)
- post the resulting trace.dat somewhere


btw, that 100000 is 400MB of nonswappable kernel memory per cpu, so if you have lots of cpus and not enough memory, adjust it down.
