Great, I have one more question. Is it possible to set the quota during run time from the host os ? Using virsh ? Thank you.
virsh schedinfo can both query and alter these cpu tunables, and that includes doing it while the guest is running.
I tried the virsh schedinfo. Here is the information regarding my libvirt :
[root@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@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.
schedinfo --cap is obsolete (it's xen-only). Rather, you want: virsh schedinfo domain to list the current settings, and virsh schedinfo domain --set vcpu_period $value --set vcpu_quota $value I haven't used it myself; I'm only going off the documentation provided by Wen Congyang, who oversaw the addition of the features. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
