seems OK, one question inside

http://gerrit.ovirt.org/#/c/31268/9/vdsm/virt/vm.py
File vdsm/virt/vm.py:

Line 2103:             self.conf['timeOffset'] = newTimeOffset
Line 2104: 
Line 2105:     def _getMergeWriteWatermarks(self):
Line 2106:         drives = [d for d in self.getDiskDevices()
Line 2107:                   if isVdsmImage(d) and d.blockDev]
s/d/drive/ - or any other more explicit name

but not really important, maybe do it only if you resubmit.
Line 2108:         allChains = self._driveGetActualVolumeChain(drives).values()
Line 2109:         return dict((entry.uuid, entry.allocation)
Line 2110:                     for chain in allChains
Line 2111:                     for entry in chain)


Line 2119: 
Line 2120:         try:
Line 2121:             watermarks = self._getMergeWriteWatermarks()
Line 2122:         except LookupError:
Line 2123:             self.log.warning("Failed to look up watermark 
information")
Is it possible that one single failure prevents the operation for all the 
drives? if so, could that be a problem?
Line 2124:             return ret
Line 2125: 
Line 2126:         for job in self.conf['_blockJobs'].values():
Line 2127:             try:
