Yes, I think it should work, if we put the pid of the forked process in cgroups.
Other child threads should go automaticaly to the parent cgroup.
I have done tests with hotplug virtio-net with vhost threads, or iothread drive,
and their threads pid go to the cgroup.

Not tested but what about this:
# in child
put current pid into cgroup
<= wouldn't this put all threads kvm creates automatically into the
