cgroup for VM - does it work properly?
Hi
I tried to restrict usage of some running VM by cpu.shares (i.e. set to
10 from original 1024) on loaded system and it seem doesn't work as I
expected... all running processes has same CPU usage (by htop) :-/
Does anyone has same experience?
Fedora 19, libvirt-1.0.5.9-1.fc19.x86_64
Thanks a lot
Martin
