Host CPU type is not supported in this cluster compatibility version or is not supported at all

Unix BeheerJan 6 2025

We recently had a host running perfectly fine in a Virtualization Manager cluster. For some reason, we had to remove the host from the cluster and add it back again. But then things went wrong, we suddenly have a non-supported CPU type. Which is strange, because the server was running fine before in that cluster. Tried installing the software again, even reinstalled the OS on the host, but still no go. We updated the BIOS firmware of the server to the latest version which did not solve our issue.

Why are we suddenly confronted with an unsupported CPU type while it ran perfectly before in the same cluster and what steps can we take to troubleshoot and fix this issue?

The software we are using:

OS Version: RHEL - 8.8 - 1.0.6.el8

OS Description: Oracle Linux Server 8.8

Kernel Version: 5.15.0 - 303.171.5.2.1.el8uek.x86_64

KVM Version: 6.2.0 - 53.module+el8.10.0+90428+8e7927cd.2

LIBVIRT Version: libvirt-8.0.0-23.2.0.1.module+el8.10.0+90363+955e9a81

VDSM Version: vdsm-4.40.100.2-1.0.14.el8

The CPU in the physical host: Intel(R) Xeon(R) Gold 6146 CPU @ 3.20GHz

Cluster CPU Type: Secure Intel Skylake Server Family

Cluster CPU Type configuration is:
Skylake-Server-noTSX-IBRS, +ssbd, +md-clear, -mpx

FYI… the stack trace shows this method as the one responsible for the exception, but not sure how it is trying to determine the local offset.

Oracle.DataAccess.Types.TimeStamp.GetLocalTZOffset()
