Title:
  live migration does not clean up at target node if a failure occurs
  during post migration

Bug description:

  If a live migration fails during the post processing on the source
  (i.e. failure to disconnect volumes) it can lead to the instance being
  shutdown on the source node and left in a migrating task state. Also
  the copy of the instance on the target node will be left running
  although not usable because neutron networking has not yet been switch
  to target and nova stills records the instance as being on the source
  node.

  This situation can be resolved as follows:

  on target
  virsh destroy <instance domain id>
  if the compute nodes are NOT using shared storage
  sudo rm -rf <instance uuid directory>

  Then use nova client as admin to restart the instance on the source node:
  nova reset-state --active <instance uuid>
  nova reboot --hard <instance uuid>

  I will investigate how to address this issue
