Nova-Compute InvalidCPUInfo #567

Closed zachelnet closed 10 months ago

zachelnet commented 1 year ago

If we try to change the CPU-Model to "Skylake-Server-noTSX-IBRS" the container nova-compute restart with following messages:

Error starting thread.: nova.exception.InvalidCPUInfo: Configured CPU model: Skylake-Server-noTSX-IBRS is not compatible with host CPU. Please correct your config and try again. Unacceptable CPU info: CPU doesn't have compatibility.

please backport following fixed for this:

https://review.opendev.org/c/openstack/nova/+/870794

Osism Release:5.2 quay.io/osism/nova-libvirt:8.0.0.20230615 quay.io/osism/nova-compute:26.2.1.20230615

berendt commented 1 year ago

We cannot make back ports for our stable releases. We can add a back port to 20231.1/Zed images. The patch will then be included in the next 5.3.0 release.

osfrickler commented 1 year ago

I've been working with upstream to get the backport https://review.opendev.org/c/openstack/nova/+/869950 merged, but due to other CI issues this is currently still blocked. If possible I would still prefer to wait for the fix to be merged upstream.
