I have installed Openstack using packstack on centos 7.

Using Dashboard, Simple Migration is working but when I try Live Migration does not migrate the instances from 1st compute to the 2nd.. neither does it give any error nor warning but the status remains unchanged (No migration takes places). Also can someone tell what needs to be checked in Disk over Commit and Block Migration options given there.

Can someone suggest what could be the reason and how to resolve this ?

start with the basics. do you have your block storage device shared between the servers ex: (mount remote.ip:/storage /var/lib/nova/instances) you're are attempting to live migrate?

Could you please elaborate the steps to share the block storage device between the servers ?
