Hi guys, here I am, reporting yet another issue with qemu. This time,
it's something that was first reported in January, and Juan proposed a
patch for it:
http://comments.gmane.org/gmane.comp.emulators.qemu/89009
[PATCH 4/5] Reopen files after migration
The symptom is, when running disk stress or any intense IO operation
in guest while migrating it causes a qcow2 corruption. We've seen this
consistently on the daily test jobs, both for qemu and qemu-kvm. The
test that triggers it is autotest stress test running on a VM with
ping-pong background migration.
The fix proposed by Juan is on our RHEL branch and such a problem does
not happen on the RHEL branch. So, what about re-considering Juan's
patch, or maybe work out a solution that is satisfactory for the
upstream maintainers?
I'll open a launchpad bug with this report.
I have just sent:
[RFC PATCH 0/2] Fix migration with NFS& iscsi/Fiber channel
Only the 1st patch on that series are needed to fix that problem. Could
you try it?
Just tried it, it conclusively fixes the corruption problems. Reported
it on the patch email.
Thanks, Juan.
