Bug 1006767

Description of problem:
win8.1-32 BSOD after do migration between host A and host B both with xbzrle=on.

Version-Release number of selected component (if applicable):
qemu-kvm-1.5.3-2.el7.x86_64
3.10.0-18.el7.x86_64

How :
race ---- I only hit this time.

Steps to Reproduce:
1.Boot a guest on host A

2.Boot the same guest on host B with listenning mode: -incoming tcp:0:5800

3.open the xbzrle on host A and host B.
(qemu) migrate_set_capability xbzrle on
4.do migration from host A to host B.

Actual results:
After migration, win8.1-32 guest BSOD.
Memory dump download link:
ftp://10.66.33.253/pub/juli_win8.1-32.dmp

Expected results:
After migration, guest can run as well.

Additional info:
I think as I have hit this BSOD, I want to fill a new bug to track whether it is a real bug. The rate of reproduce this issue is very low. I run dozens of times, hit this issue only once.
