Reboot Screen dump
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? Can QE re-test with virtio devices to narrow down the issue? 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. Please try to reproduce with latest qemu-kvm/kernel (In reply to comment #5) > Can QE re-test with virtio devices to narrow down the issue?

Can you try with qcow2 instead of raw? As per the earlier report, raw was fine but qcow2 was not. (In reply to comment #12) > Can you try with qcow2 instead of raw?

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). (In reply to comment #12) > > Can you try with qcow2 instead of raw? As per the earlier report, raw was fine > but qcow2 was not. 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. *** This bug has been marked as a duplicate of bug 612481 *** |
