Open Stack

Hi all, I have configured openstack kilo setup in debian jessie with one
controller node and two compute nodes. I have used glusterfs for shared
storage. I have mounted the shared storage in /var/lib/nova/instances on
both nodes.  I can do normal migration of vm’s between nodes.. But
live-migration  throws following error.. Pls do guide


*Libvirt version: 2.3*
*Qemu version: 1.2.9*



Log of  current node where the vm resides
