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
