Description Yanan Fu 2015-07-31 05:43:38 EDT
Description of problem:
stop guest when the guest in "working on updates" stage,then migrate to dst host,then the dst guest "working on updates" and boot repeatedly.

Version-Release number of selected component (if applicable):
kernel: 3.10.0-300.el7.x86_64

How reproducible:

Steps to Reproduce:
1.start VM in src host.	
2.start listening mode in dst host <command Line> -incoming tcp:0:5800

3.Guest in the status:"working on updates  30% finished", stop guest and then migrate to dst host:
(qemu)migrate -d tcp:$dst_host_ip:5888

4.after migration finished,
in src host:(qemu): info migrate----->Migration status: completed
in dst host:(qemu): info status---->VM status: running

but guest show step as following:
1. "working on updates 0~30% complete",
2. "restaring"
3. boot and we can see the seabios interface
4. ""please wait"-->"Geting windows ready"--->"working on updates 30~100% complete"
5. "restaring" 
6. "Geting windows ready"
7. then repeat the above steps: 1~6

Actual results:
repeat update and boot.

Expected results:
guest should boot successfully.

Please disable "reboot on fail" in Windows before you start the 
upgrade, and then reproduce it; when Windows fails after the 
migration please save the memory dump and attache it here.

Please uncheck "Automatically restart" (see pages 31 and 32 http://www.slideshare.net/YanVugenfirer/windows-guestdebugging-kvmforum2012) option for blue screen. After a crash, enter safe mode and collect the crash dump file.

Comment 4 Yanan Fu 2015-08-11 01:55:39 EDT
I have retest this bug for several times, and i find the guest will reboot during install updates even without migration.
I think it should be normal phenomenon,as some updates need to reboot.
Comment 5 Yanan Fu 2015-08-11 02:04:11 EDT
additional information:
In the end, after all the updates finished, can enter the guest successfully,and the guest work normallly.
