I see "-cpuuinits" qemu option in source code, 
also I see it not an "official" qemu option, it come from a patch fairsched.diff


but i'm talking of using cgroups. (that the way that libvirt use)
like here:  http://berrange.com/posts/2009/12/03/using-cgroups-with-libvirt-and-lxckvm-guests-in-fedora-12/



> libvirt do fairsched with kvm and cgroups without any problems . 

>> with kvm and openvz?? 

normally yes, that's the beauty of cgroup, it's work with any process.
But it'll make tests to be sure ! (if think cgroup support is new in openvz, so not sure vztcl put cpuunits in cpu.shares)
