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

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
