[ovirt-users] MoM is failing!!!

Hi, after running systemctl status vdsm I am getting that it's running and this message at the end. Oct 16 14:26:52 hostname vdsmd[2392]: vdsm throttled WARN MOM not available. Oct 16 14:26:52 hostname vdsmd[2392]: vdsm throttled WARN MOM not available, KSM stats will be missing. Oct 16 14:26:57 hostname vdsmd[2392]: vdsm root WARN ping was deprecated in favor of ping2 and confirmConnectivity how critical it is? and how to solve that warning? I am using libvirt Cheers
