Looks good expect thread safety when accessing HSM.pools dict.
http://gerrit.ovirt.org/#/c/27478/2/vdsm/storage/hsm.py
File vdsm/storage/hsm.py:
Line 418: self.domainStateChangeCallbacks.add(callbackFunc)
Line 419:
Line 420: def _onDomainStateChange(self, sdUUID, isValid):
Line 421: for pool in self.pools.values():
Line 422: pool.domainStateChangeEvent(sdUUID, isValid)
This happens from an event thread - I'm sure that this is not thread safe as is.
Don't we use locking when accessing the pools dict?

Line 424: def _hsmSchedule(self, name, func, *args):
Line 425: self.taskMng.scheduleJob("hsm", self.tasksDir, vars.task,
Line 426: name, func, *args)

Line 138: return self._backend
Line 139:
Line 140: def domainStateChangeEvent(self, sdUUID, isValid):
Do we have this pattern - xxxEvent? If we don't I prefer something like "domainStateChanged" or "domainStateDidChange" (if you have time and like this direction).
Line 141: if isValid and sdUUID in self.getDomains():
Line 142: self._refreshDomainLinks(sdCache.produce(sdUUID))
