First of all thanks for quick reply. 
Documentation does not mention much about Volume-backed live migration. 
Is it tested, I mean supported and working. 
I will try Block live migration as no storage is required.

Wel, depends on what you call "supported".
Yes, it is possible. 
Will it always work? Probably not until you look at the bugs below.
They have been fixed recently but they might not be merged with the version you are running: 
https://bugs.launchpad.net/nova/+bug/1270825
https://bugs.launchpad.net/nova/+bug/1082414

There might be more issues but I hit the ones mentioned above.
Have a look at the docs to configure it:
http://docs.openstack.org/admin-guide-cloud/content/section_configuring-compute-migrations.html

Cheers,

It's dated and getting the patches backported has proven to take forever, but I did a write up and testing on this a while back [1].  Should still be accurate.
Thanks,John
