Patch Set 8: (3 comments) I can't say there is something clearly wrong with the change, but it looks a bit suspicious to me. While it probably shouldn't cause regressions, I'm not sure it handles the problem completely. Maybe just some source comment is missing, maybe something should be done a bit differently. I don't know now. https://gerrit.ovirt.org/#/c/44989/8/vdsm/virt/vm.py File vdsm/virt/vm.py: Line 251: vmdevices.graphics.initLegacyConf(self.conf) Line 252: self.cif = cif Line 253: self.log = SimpleLogAdapter(self.log, {"vmId": self.conf['vmId']}) Line 254: self._destroyed = threading.Event() Line 255: self._destroyRequested = threading.Event() We shouldn't use camel case for attribute names, right?
