subject is as the #comment 39 of bug1435521, huiqing, please help to check this bug for x86_64, thanks

This bug is verify pass for powerpc both on qemu-kvm-rhev-2.6.0-28.el7_3.10.ppc64le and qemu-kvm-rhev-2.9.0-2.el7.ppc64le. 
Bug verification is as below:
Host version:

3.10.0-514.21.1.el7.ppc64le
mem: 4G
vcpu: 4

scenario I:
1)steps are same with bug description.
2)result:
migration completed and vm works well.
I have test this scenario for 20 times, and all the result are pass.

scenario II:
Refering to comment 32, I have changed the qemu cli to boot guest:

So, this bug is fixed for ppc , huiqing, could you help to verify this bug for x86_64? thanks

Test 7.3.z->7.4 postcopy migration as comment #32, migration can be finished.
