On engine 4.4.10.7 From web UI launching VNC or noVNC console on a VM: from engine.log 2022-03-15 16:55:28,682Z ERROR [org.ovirt.engine.core.bll.SetVmTicketCommand] (default task-22) [64e416b3] Command 'org.ovirt.engine.core.bll.SetVmT icketCommand' failed: EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed t o SetVmTicketVDS, error = General Exception: ('unsupported configuration: VNC password is 12 characters long, only 8 permitted',), code = 100 (Faile d with error GeneralException and code 100) searching in internet I found a possible explanation: OK for info. It looks like libvirt 8 was accidentally included in the oVirt Node ISO 4.4.10 3rd March. Therefore use the February one libvirt 7.10 or if you're using upstream then the following command will work for you: dnf install libvirt-7.10.0
We currently have no plan to release another 4.4.10 version of NODE In 4.5 is is supposed to be fixed by https://gerrit.ovirt.org/c/ovirt-engine/+/118313
