We need to create GuestIoTuneOptional collector in MOM and then use it in VDSM's configuration file for MOM.
Comment 2 Roy Golan 2016-06-15 06:00:27 UTC 
Is the evaluation of policy is such inclusive? isn't it triggered with minimum requirements? If not it should be

Uh? That is the whole point of this bug. The currently used GuestIoTune adds the io_tune variables to the list of required values.
