Open Stack

I have openstack with ceph storage setup and trying to test Live
migration but somehow it failed and showing following error

nova.conf

# ceph rbd support
live_migration_uri = "qemu+tcp://%s/system"
live_migration_tunnelled = True

libvirtd.conf

listen_tls = 0
listen_tcp = 1
unix_sock_group = "libvirt"
unix_sock_ro_perms = "0777"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"
auth_tcp = "none"


This is the error i am getting, i google it but didn't find any reference
