Hi Wayne,
Thanks for your reply.

On my slave node, if I run following command,  I am able to see instances
but state is ' shut off '
root@openstack3:~# virsh list --all
 Id Name                 State
----------------------------------
  - instance-0000002a    shut off
  - instance-0000003c    shut off
  - instance-0000003e    shut off
  - instance-00000040    shut off

root@openstack3:~#

I went ahead and started instances manually,  I have got following errrors.
virsh # start instance-0000002a
*error: Failed to start domain instance-0000002a
error: operation failed: failed to retrieve chardev info in qemu with 'info
chardev'*

virsh #

I have checked the log files also,
