[ovirt-users] Unable to install OVirt 4.4.6 on IvyBridge

Hi, I'm attempting to build an oVirt node on a server. The host is an RHEL 8.4, I'm attempting to install OVirt 4.4.6 as per instructions at https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng.... I'm receiving the following error: [ INFO ] The host has been set in non_operational status, deployment errors: code 156: Host redacted.com moved to Non-Operational state as host CPU type is not supported in this cluster compatibility version or is not supported at all, code 9000: Failed to verify Power Management configuration for Host redacted.com., [ INFO ] skipping: [localhost] [ INFO ] You can now connect to https://redacted.com:6900/ovirt-engine/ and check the status of this host and eventually remediate it, please continue only when the host is listed as 'up' Now, I note that initially lm_sensors was unable to detect CPU temperatures, which was subsequently resolved (I don't recall how), however the issue still remains. The CPU is an Xeon E5-2630 (IvyBridge). I cannot see any definitive CPU support catalog, so I'm unsure if this is no longer supported. Within engine-logs-2021-11-13T12:22:10Z/log/ovirt-engine/engine.log, there were occurrences of `<model fallback='forbid'>IvyBridge-IBRS</model>`. From what I can tell, spectre/meltdown bugs have been mitigated: ``` egrep -e "model|cpu family|stepping|microcode" /proc/cpuinfo | sort | uniq cpu family : 6 microcode : 0x42e model : 62 model name : Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz stepping : 4 ``` In the installation documents, IvyBridge seems supported but the evidence above suggests it may not be. Can anyone advise on if this processor is _actually_ supported, and if so how I can remediate the issue? Thanks!
