Open Stack

Hi all

I have created one openstack using one controller node and one compute node
both installed using devstack.I'm running one instance on controller node
and want to migrate it to over compute node.
I'm using following link for this.

http://docs.openstack.org/grizzly/openstack-compute/admin/content/live-migration-usage.html
http://docs.openstack.org/grizzly/openstack-compute/admin/content/configuring-migrations.html

The output of  nova-manage vm list  on the compute node is as follows..
