Can you do an independent live merge test just with plain libvirt and explain how exactly you can trigger it? For example, I wrote some notes here which I normally use to test live disk image chain merge: http://wiki.libvirt.org/page/Live-merge-an-entire-disk-image-chain-incl= uding-current-active-disk Can you reproduce your bug when testing with a variant of the above? > Here are the previous mails, > = > http://lists.ovirt.org/pipermail/users/2015-May/033083.html > = > The problem is on a system with everything on the latest version, > CentOS 7.1 and ovirt 3.5.2.1 all upgrades applied. > = > This Problem did NOT exist before upgrading to CentOS 7.1 with an > environment running ovirt 3.5.0 and 3.5.1 and Fedora 20 with the > libvirt-preview repo activated. > = > I think this is a bug in libvirt, not ovirt itself, but i am not sure. > The actual file throwing the exception is in VDSM > (/usr/share/vdsm/virt/vm.py, line 697). > = > We are very willing to help, test and supply log files in anyway we > can. > = > Regards Soeren > = -- = /kashyap --===============7699410738711613546==--
