Hi all,
please note that I also tried to migrate one of my hosts from CentOS 8
to CentOS Stream 8.
After the reboot I received the following message:
The host CPU does not match the Cluster CPU Type and is running in a
degraded mode. It is missing the following CPU flags: model_IvyBridge,
spec_ctrl. Please update the host CPU microcode or change the Cluster
CPU Type.
I downgraded the edk2-ovmf package to the following version:
20200602gitca407c7246bf-5.el8
The following version was installed before: 20210527gite1999b264f1f-1.el8
But still the issue is present for me.
I'm running latest 4.4.7 and my cluster version is 4.6.
Best regards
Christoph

The issue was with edk2-ovmf package update, rolling that package back
and it started recognizing the CPU and host coming up... tested on one
host and worked fine.
Thanks & Regards,

Already trying several things, seem kernel update doesn’t make this
problem happen. Already tried to yum update exclude kernel, the issue
still happened.
Thanks.

I also end up with the same problem today. How did rollback yum i see
many yum updates in the yum history.
Here is what the error says.
The host CPU does not match the Cluster CPU Type and is running in a
degraded mode. It is missing the following CPU flags: model_IvyBridge,
spec_ctrl. Please update the host CPU microcode or change the Cluster
CPU Type.
