MOM runs inside the VDSM process. We want to make it possible to run as standalone process, to the reduce the pressure on the python GIL.
Running MOM separately also make it easier to profile and to evaluate the performances of it, and also of VDSM.
martin, please add steps to verify this bug
just to make sure, 3.6 mom installation is still a dependecy of the vdsm rpm or one needs to install mom separately?
Shira: Just start VDSM and run any of your MOM scenarios (ballooning, ksm, …) + check whether there is a separate process running (using for example ps or systemctl status mom-vdsm).
Roy: VDSM still depends on mom via RPM dependency.
Verified on :
i run the regular tests and check that the mom service is running :
[root@dhcp160-245 ~]# systemctl status mom-vdsm
● mom-vdsm.service - MOM instance configured for VDSM purposes
