Public bug reported:

Migration failed when trying to do a cold migration for a nova LVM
backed instance.

Error message:

Error: Failed to perform requested operation on instance "migr-test2",
the instance has an error status: Please try again later [Error:
Unexpected error while running command. Command: scp -r
/var/lib/nova/instances/733f5bbc-330f-4a73-a418-bb3c28b2c35b_resize

192.168.56.47:/dev/ssd_nova/733f5bbc-330f-
4a73-a418-bb3c28b2c35b_disk.eph0

Seems the nova libvirt driver not handling the LVM path correctly on the
source and didn't create the LV on the dest host.
