Title:
  live-migration --block-migrate fails without config drive

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  I'm using the libvirt driver

  I've configured libvirtd and nova so that block migration can occur.

  migration I get this error on my source node, concerning the
  incompatibily between live-migration and the config-drive attached to
  my VM  :
