how to fix time-drift on el8 hosts?
Hello, Engine complains about my fresh el8 ovirt 4.4.3 node host: "Host hadriacus has time-drift of 3202 seconds while maximum configured value is 300 seconds." I tried to fix it with these commands: sudo chronyc -a makestep chronyc sources chronyc tracking ... but the host is still not synchronized. How should I proceed? -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet@abes.fr
Are you sure that the problem is not in the HostedEngine ? Sync your host and then verify the situation on the HE Best Regards, Strahil Nikolov В четвъртък, 7 януари 2021 г., 11:46:09 Гринуич+2, Nathanaël Blanchet <blanchet@abes.fr> написа: Hello, Engine complains about my fresh el8 ovirt 4.4.3 node host: "Host hadriacus has time-drift of 3202 seconds while maximum configured value is 300 seconds."

hi, we have setup a ovirt system with 9 hosts. we will now add three more nodes and we have to exchange from each host the SSH public keys to the other one. we use ovirt 4.3 on centos 7. how did you exchange the SSH keys? did you have ansible to do this or other tools? ssh-copy-id is not the best process here and waste time. br marcel
It takes a very small amount of effort to do it one time using ssh-copy-id but I suppose you could easily do it with Ansible too. On Thu, Jan 7, 2021 at 11:42 AM marcel d'heureuse <marcel@deheureu.se> wrote:

We recently had a similar discussion in the Bhyve community. The consensus was that it is not desirable to use both time sync mechanisms in parallel: guest-tools and chronyd (or ntpd) Now it would be good to know if oVirt-guest-agent is attempting to sync the VM's clock with the host clock. If so, it may be worth trying to disable chronyd/ntpd and see if the time sync by the guest-agent does a better job. In any case, the host's clock should be properly synchronized with the real world time. Kind regards Toni Feric On 07.01.21 15:43, Strahil Nikolov via Users wrote:

I think this message indicates a time difference between the host and the engine machine, unrelated to any VM. Perhaps check the clock on the engine machine and the host: 1. If indeed they are different, somehow fix them - that's unrelated to oVirt - configure both to use same (local/nearby) ntp server, sync, etc. 2. If they are close/similar, perhaps it's a bug in the engine. You can try to restart it and see if this helps. If it indeed looks like a bug, perhaps open one in bugzilla. Good luck and best regards, -- Didi
