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) :-/
How exactly are you changing the cgroup settings? Are you trying to directly modify cgroup files (unsupported), or using the libvirt API (such as via virsh schedinfo)?
Via mounted virtualfs - /sys/fs/cgroup/cpu/machine/<name-of-VM>/{emulator,vcpu0}/cpu.shares
Won't work, because it goes behind libvirt's back. Use virsh instead. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
