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.
Thanks,
Lucas
