I tried the virsh schedinfo. Here is the information regarding my libvirt : 

[root at sbc11 ssubbiah]# virsh version
Compiled against library: libvir 0.9.4
Using library: libvir 0.9.4
Using API: QEMU 0.9.4
Running hypervisor: QEMU 0.12.1

When i use "[root at hgcc11 ssubbiah]# virsh schedinfo rubis_ws --cap 50" , I dont see the cap value being set and I am able to see only cpu shares. 

Scheduler      : posix
cpu_shares     : 1024
