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

Comment 6 xianwang 2017-05-24 06:26:57 EDT

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:
(host1)
RHEL-7.3-20161019.0 Server ppc64le
kernel-3.10.0-514.17.1.el7
qemu-kvm-rhev-2.6.0-28.el7_3.10.ppc64le

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
