libvirtd debug log
Jiri, could you please check https://bugzilla.redhat.com/show_bug.cgi?id=1305530#c5 https://bugzilla.redhat.com/show_bug.cgi?id=1305530#c6 ? So looking at the code, this seems to be the same issue as described in bug 1254164. We just need to backport the patches for RHEL-6. I'll clone that bug for 6.8 and make this one depend on it.

I'll clone that > bug for 6.8 and make this one depend on it. Thanks for the answer! I don't know if this helps, or if it was already evident, but I think there are some differencies worth stressing: 1. this time we DO NOT have hooks involved (in 1254164 we had them) 2. AFAIU 1254164 wes due to some backports affecting libvirt 1.2.8 on RHEL7.1, I may be wrong on this Reference https://bugzilla.redhat.com/show_bug.cgi?id=1254164#c7 (In reply to Francesco Romani from comment #10) > 1. this time we DO NOT have hooks involved (in 1254164 we had them) Yeah, RHEL-6 does not support restore hooks, but the code path is the same > 2. AFAIU 1254164 wes due to some backports affecting libvirt 1.2.8 on > RHEL7.1, I may be wrong on this It affected 7.1 because it was fixed upstream after 1.2.8 was released. I reproduced the issue (see bug 1307094 for steps), backported the fixes from upstream, and checked it's all working for me. Francesco, could you try the scratch build from https://brewweb.devel.redhat.com/taskinfo?taskID=10480048 and check it fixes this bug?

Francesco, could you try > the scratch build from > https://brewweb.devel.redhat.com/taskinfo?taskID=10480048 and check it fixes > this bug? I did a quick test and looks good with the patched rpms. WORKSFORME. On Vdsm side, we'll just need to consume the libvirt fix. Will post a patch once we know on which libvirt version we should depend. closing as we do not intend to rebuild just to pick up a libvirt rpm. Once libvirt is out on properly updated system this problem should be fixed |
