Cgroups vs Tasksets in KVM

Question

I have a CentOS 6 host for several KVM VMs with FreeBSD as guest.

I want to bind each VM to use no more than one core at once. What would you suggest to use, Cgroups or Tasksets?

Answer 1

I think cgroups are the preferred method with EL6 now, especially with virtualization. Taskset is best for individual processes, but cgroups are closer to the notion of shielding/containers.
