Seems the old faisched patch still works, for example try:
# kvm -id 300 -cpuunits 1000
Then you can see the created cgroup in:
# ls /proc/vz/fairsched/300/
So all we need to to is to add parameter --cupunits to qemu-server and pass it to kvm.
And we already do that with qemu-server! It is just disabled if you use virtio (because
we got strange behavior earlier)
