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.
