Description of problem:
Reboot guest after ping-pong migration with dd operation inside guest, remote-viewer display abnormal.
Version-Release number of selected component (if applicable):
1/3, hit once, can't be reproduced so far.
Steps to Reproduce:
1.Launch guest with -vnc:10 --device cirrus-vga,id=video0,bus=pci.0,addr=0x4

4.Reboot inside guest.
Display abnormal as attached picture shows, keyboard and mouse doesn't work; but it could ssh remotely and do other operations successfully, and no errors in dmesg.
Guest reboot correctly
Since this is a corner case and we can't reproduce it, I'm closing it due to low priority. Please reopen if it ever happens again.
