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

upgraded. that’s a newer version than the one below

The following version was installed before: 20210527gite1999b264f1f-1.el8

But still the issue is present for me.

I’m not aware of any issue with the virt stack packages in Stream, that edk2-ovmf issue has been fixed few weeks back, the new version is the right one, but maybe you have other outdated packages? Also please refresh host capabilities after each such package change. There also could be a microcode change for IvyBridge that you’ve missed (or intel didn’t fix for your particular cpu)…perhaps it’s good enough to just change the Cluster CPU to SandyBridge instead.

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.

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.

Hi Lucia, Hi Michal, thank you so much for getting back to me. I have downgraded the edk2-ovmf package two times to 20200602gitca407c7246bf-4.el8. This have solve the issue for me. Means I'm able to activate the host on CentOS Stream 8 again. Does this mean that this will be fixed in future versions? Best regards Christoph Am 28.07.21 um 09:58 schrieb Lucia Jelinkova:

Hi Christoph,

The 20200602gitca407c7246bf-5.el8 is the "broken" one [1], try downgrading to the older version (I have 20200602gitca407c7246bf-4.el8_4.1).
