Hi All,

I deployed openstack based on icehouse and having a problem with live migration, instance status stays at "Migrating" forever and I get the following error:

**#root@control:~# nova live-migration 3e52960e-659c-44f6-85bc-dbd5fc3ba66e compute1
ERROR: Live migration of instance 3e52960e-659c-44f6-85bc-dbd5fc3ba66e to host compute1 failed (HTTP 400) (Request-ID: req-49dd8597-1462-440a-a964-593a93bcc477)**

Background: Ubuntu 14.04 LTS 4 nodes, control/network, and 3 compute nodes. libvirt0 1.2.2-0ubuntu13.1 KVM as hypervisor on physical HW Shared storage is used and mounted at /var/lib/nova/instances Steps followed to enable live migration is located here: http://docs.openstack.org/admin-guide-cloud/content/section_configuring-compute-migrations.html (http://docs.openstack.org/admin-guide...)

Error in nova-api:
