Bug description:
  Brief Description
  -----------------
  Live migration of UEFI booted instance failing unexpectedly (rollsback)

  Severity
  --------
  Major

  
  Steps to Reproduce
  ------------------
  1: Get/Create ge_edge image
  2: Create a flavor with 1 vcpu
  3: Add following extra specs: {'hw:cpu_policy': 'dedicated'}
  4: Create a volume from ge_edge image
  5: Boot a ge_edge VM with above flavor from volume
  6. Check topology of vm b69eb997-0477-43f5-a2dc-6840e13cadcd on controller, hypervisor and vm
  7: Live migrate ge_edge VM
  [2018-09-15 21:38:21,722]
  8: Ping vm from NatBox after live migration
  9: Check topology of vm b69eb997-0477-43f5-a2dc-6840e13cadcd on controller, hypervisor and vm
  10: Cold migrate vm and check vm is moved to different host
  11: Ping vm from NatBox after cold migration
  [2018-09-15 21:40:10,847]
  12: Check topology of vm b69eb997-0477-43f5-a2dc-6840e13cadcd on controller, hypervisor and vm
  [2018-09-15 21:40:43,316]
  13: Swact active controller
  [2018-09-15 21:41:05,746]
  14: Ensure ge_edge vm can still be live-migrated after swact
