I have an ovirt 4.4 installation whit self-hosted engine where the agent seems to have died. The VMs are still running, so I assume that the engine itself is still running (is this a wrong assumption ?). Can I restart the agent without affecting the running VMs, that is how will restarting the agent affect the running VMs ? If I can restart the agent, what's the correct way of doing it ?
If the engine is down, the VMs will continue to run. You just won't be able to start/migrate/configure/etc them. If the engine VM is still running, you may want to SSH into it and look at the state of the system to see if you can see what went wrong. systemctl status 'ovirt*' may tell you if just a single service is down (such as ovirt-engine). You might also check the logs in /var/log/ovirt-engine If the VM is down or inaccessible, SSH into one of the hosts capable of running the engine and run the following to check VM status: hosted-engine --vm-status This should tell you if and whre it's running. If it isn't dead, You can stop it with: hosted-engine --vm-shutdown Check the status and wait until it's actually down, then you can start it up again: hosted-engine --vm-start
