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_engine.... 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!

Hi, could you please run the following command on the non responsive host and post the output here? virsh domcapabilities Also, could you please go to the Webadmin UI and check the warning signs on the host list and host detail to see, what flags is the host missing? You can also check the CPU Type on the host's detail page + all available cpus in the info icon next to it. Regards, Lucia On Mon, Nov 15, 2021 at 6:30 AM <clin.yolo@gmail.com> wrote:

Hi, Thank you for your response, it solved the issue.
virsh domcapabilities
virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf domcapabilities error: failed to get emulator capabilities error: internal error: unknown feature amd-sev-es This appeared to be the bug, https://bugzilla.redhat.com/show_bug.cgi?id=1961558 , which as per https://serverfault.com/questions/1065246/virsh-reporting-unknown-feature-am... I ran `yum downgrade edk2-ovmf`. After which domcapabilities reported data correctly. I re-ran the engine installer and that completed successfully. For those playing at home, an additional symptom I noticed was that in 'Edit Cluster' for the default cluster, I could not change CPU Type from 'Auto Detect' - it was an empty drop-down. CPU Architecture was also locked as undefined. Thanks for your help!
