Hi,Wilson,
    We are seeing this issue in Icehouse too , and we fixed it by modify the nova code. I think you can do it in Juno too.

Subject:  [Openstack] Live Migration + Ceph + ConfigDrive



Hello All,

Currently in Juno we are seeing an issue with attempting to live-migrate an instance with a configdrive attached.
"NoLiveMigrationForConfigDriveInLibVirt: Live migration of instances with config drives is not supported in libvirt unless libvirt instance path and drive data is shared across compute nodes."
 I have found this bug https://bugs.launchpad.net/nova/+bug/1351002 however it is geared toward NFS, has any work taken place in regards getting this fixed for Ceph users?


Thanks!
