Hi,
To ensure if compute-service are UP you should verify output of 'nova
service-list'.
You can verify compute's log on source & destination and your NTP sync.
By default Openstack doest'nt allow live-migration, you need to modify
live_migration_flag on nova.conf and add listen support to libvirt.
I use the same setup as you, but on Ubuntu12.04 (package are the same)
and live-migration works perfectly.
Good luck.

Hi!
We have an Icehouse system running with librbd based Cinder and Glance
configurations, storing images and volumes in Ceph.
Configuration is (apart from network setup details, of course) by the
book / OpenStack setup guide.
Works very nicely, including regular migration, but live migration of
virtual machines fails. I created a simple machine booting from a volume
based off the Ubuntu 14.04.1 cloud image for testing.
Using Horizon, I can move this VM from host to host, but when I try to
Live Migrate it from one baremetal host to another, I get an error
message “Failed to live migrate instance to host ’node02’".
The only related log entry I recognize is in the controller’s
nova-api.log:

I cannot see anything of value on the destination host itself.
New machines get scheduled there, so the compute service cannot really
be down.
In this thread Travis
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-March/019944.html
describes a similar situation, however that was on Folsom, so I wonder
if it
is still applicable.
Would be great to get some outside opinion :)
Thanks!
Daniel
