RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Mike Cao 2010-07-13 06:30:56 UTC 
Description of problem:
Do ping-pong migration with cpu loaded win2008 R2 guest,cause guest reboot.

Version-Release number of selected component (if applicable):
# uname -r
2.6.32-44.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.91.el6.x86_64


How reproducible:
always

Steps to Reproduce:
1.start a VM in the src host,eg:
/usr/libexec/qemu-kvm -M rhel6.0.0 -enable-kvm -m 8192 -smp 8,sockets=8,cores=1,threads=1 -name win2k8r2 -uuid 93f30ee8-3af0-4c76-afd6-c166c7413fcc -nodefconfig -nodefaults -monitor stdio -rtc base=localtime -boot c -drive file=/dev/vgtest/win2k8,if=none,id=drive-ide0-0-0,boot=on,format=raw,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -netdev tap,id=hostnet0 -device e1000,netdev=hostnet0,id=net0,mac=52:54:00:72:a4:a8,bus=pci.0,addr=0x4 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -device usb-tablet,id=input0 -vnc :3 -k en-us -vga std -device AC97,id=sound0,bus=pci.0,addr=0x5 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3
2.in the Guest ,run cpu-burn tools to load cpu ,In my case,I open 5 cpu-burn ,load cpu usage to 70%-80%
3.in the dest host # <commandLine> -incoming tcp:0:5888
4.in the src host (qemu) migrate -d tcp:<ip>:5888
5.use vncviewe to view the guest
  
Actual results:
After migration ,the guest is very slow for responding user's operation. After more or less 1 minute ,the guest reboot.

Expected results:

Comment 4 Amit Shah 2010-07-15 11:12:24 UTC 
The cmd line uses IDE device for the hard disk. This could be related to the h/d save/restore bug; Juan, can you confirm it's that?
Comment 5 Dor Laor 2010-07-22 20:45:17 UTC 
Can QE re-test with virtio devices to narrow down the issue?
Comment 8 Juan Quintela 2010-07-26 18:16:27 UTC 
We have backported this patches with my ide subsections work.  Upstream (and patches posted) are wrong (version is changed in the wrong place).

Trying to reproduce locally.
Comment 9 Dor Laor 2010-07-27 09:58:45 UTC 
Please try to reproduce with latest qemu-kvm/kernel

Can you try with qcow2 instead of raw? As per the earlier report, raw was fine but qcow2 was not.

> but qcow2 was not.    

Ah; I confused this with another bug report. Even then, it'll be interesting to see results with qcow2.
Comment 14 Juan Quintela 2010-07-29 00:53:58 UTC 
I think this is a duplicate of 618601. raw works and qcow2 fails.  qcow2 can fail when migration with stressed IO.  I sent patches for this issue today, and hope that I will get ack's tomorrow.

/me re-reads and sees this only happens with raw.  raw has the same issue that qcow2 here, but race should be way smaller (I haven't reproduced it there in the past).

Test with virtio qcow2 images and ide qcow2 images both 10 times with -smp 2 -m 4G 


Actual Results:
After migraion ,Guest does not reboot. 
Can not reproduce this issue.

Thanks; this was the ide migration bug, marking as a dupe of the one that fixed it.
