Public bug reported:
Description
===========
During live-migration with --block-migrate enable, CPU check always fail even
both source host and destination host are identical in term of hardware and
software version.
Steps to reproduce
==================
# nova live-migration --block-migrate instance computenode2
After a bit, check on computenode2, I can see the error in the log below
Expected result
===============
instance got moved to computenode2
Actual result
=============
instance is still on its old compute node
Environment

======
The live-migration will work as expected if I change the nova.conf config to
any one of the config below:
1- Config1:
[libvirt]
virt_type = qemu
2- Config2:
[libvirt]
virt_type = kvm
cpu_mode=custom
