Open Stack

Hi all

I have installed openstack using devstack and nearly all the functionality
is working fine.
However I'm getting an issue during live migration .
I'm creating a stack of one controller node and two compute nodes i.e
Compute node 1 and compute node 2 .I'm booting one VM at compute node 1 and
need to migrate it over compute node 2.
For this I'm using NFS which is working fine.

Also I have enabled
live_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE
in /etc/nova.conf over both the compute nodes and over controller node.


However when I apply nova live-migration command after restarting the
nova-compute service using screen session the VM is not able to migrate.

Below are the logs after restarting nova-compute service ..

Also find the attached screanshot describing the complete error.
Please help regarding this.
