This seems as a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1115126 and seems related to the version of libvirt in use. this issue was observed by ebenahar as well. Adam, can you take a look? (as you looked into the bug i've attached) thanks, Liron Sorry, not a duplicate - a clone of.

It seems like the most likely explanation but without the full vdsm log during a failure I won't be able to confirm it. I need to see the error messages from libvirt calls which aren't captured by this grep of the vdsm logs. Martin Tessun, could you attach a full vdsm log from when the problem happened? Hi Adam, log is attached. The relevant part seems to be this snippet: Thread-153::INFO::2015-02-06 16:09:16,701::clientIF::321::vds::(prepareVolumePath) prepared volume path: /rhev/data-center/84ee5743-d9e6-40f7-bc84-3ee68455acc6/f6589b8e-4eed-4e3a-91e2-5726ba39a4dd/images/a6b6478b-a1a7-44a8-9669-7d6ba236e774/3a436041-a566-4bca-83b2-7cc999339d3a Thread-153::DEBUG::2015-02-06 16:09:16,701::vm::4075::vm.Vm::(snapshot) vmId=`11e5229d-d751-4f48-ba1f-d7f0b8f207f9`::<domainsnapshot> <disks> <disk name="vda" snapshot="external" type="block"> <source dev="/rhev/data-center/84ee5743-d9e6-40f7-bc84-3ee68455acc6/f6589b8e-4eed-4e3a-91e2-5726ba39a4dd/images/a6b6478b-a1a7-44a8-9669-7d6ba236e774/3a436041-a566-4bca-83b2-7cc999339d3a" type="block"/> </disk> </disks> </domainsnapshot> Thread-153::DEBUG::2015-02-06 16:09:16,708::libvirtconnection::124::root::(wrapper) Unknown libvirterror: ecode: 67 edom: 35 level: 2 message: unsupported configuration: source for disk 'vda' is not a regular file; refusing to generate external snapshot name Thread-153::DEBUG::2015-02-06 16:09:16,708::vm::4096::vm.Vm::(snapshot) vmId=`11e5229d-d751-4f48-ba1f-d7f0b8f207f9`::Snapshot failed using the quiesce flag, trying again without it (unsupported configuration: source for disk 'vda' is not a regular file; refusing to generate external snapshot name) Thread-153::DEBUG::2015-02-06 16:09:16,714::libvirtconnection::124::root::(wrapper) Unknown libvirterror: ecode: 67 edom: 35 level: 2 message: unsupported configuration: source for disk 'vda' is not a regular file; refusing to generate external snapshot name Thread-153::ERROR::2015-02-06 16:09:16,714::vm::4100::vm.Vm::(snapshot) vmId=`11e5229d-d751-4f48-ba1f-d7f0b8f207f9`::Unable to take snapshot Traceback (most recent call last): File "/usr/share/vdsm/vm.py", line 4098, in snapshot self._dom.snapshotCreateXML(snapxml, snapFlags) File "/usr/share/vdsm/vm.py", line 928, in f ret = attr(*args, **kwargs) File "/usr/lib64/python2.6/site-packages/vdsm/libvirtconnection.py", line 92, in wrapper ret = f(*args, **kwargs) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 1679, in snapshotCreateXML if ret is None:raise libvirtError('virDomainSnapshotCreateXML() failed', dom=self) libvirtError: unsupported configuration: source for disk 'vda' is not a regular file; refusing to generate external snapshot name Cheers, Martin Thanks Martin, This is indeed a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1115126 (In reply to Adam Litke from comment #10) > Thanks Martin, > > This is indeed a duplicate of > https://bugzilla.redhat.com/show_bug.cgi?id=1115126 Thanks guys.
