[Openstack] Live migration problem in OpenStack ESSEX

I am using Ubuntu 12.04 Precise Pangolin with multi compute node environment running on KVM / libvirt. The nova command that I use is "nova live-migrate instanceID hostID" and via API, I am passing the same information in the request body.

I haven't modified any configuration in the libvirt. Can I get to know the necessary configuration details in order to solve the problem?

Can you show the details of your OS, software environment and your commands doing live migration?

Live migration need some pre-configuration and some modifications to libvirt/nfs configuration.

Hallo all,

I am trying to perform live migration from one compute node to another (using Nova  APIs and commands) and I am getting an error HTTP 400 and the log file says "Remote error: FileNotFound File tmpSoFy35 could not be found". I am using OpenStack ESSEX.

Could anybody suggest solutions to get rid of this problem?
