Title:
  Live migration artifacts are not cleaned up properly when queued live
  migration is aborted

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) xena series:
  New

Bug description:
  Bug #1949808 describes one of the problems affecting aborted queued
  live migrations: VM's status is not reverted back to ACTIVE and VM is
  left in MIGRATING state.

  However that's not the single problem with aborted queued live
  migrations: some changes (port bindings on destination host, resource
  allocations and possibly instance's pci_requests) are introduced by
  Nova control plane before live migration actually started by source
  compute host. Those left-overs should also be removed.
