Hi Lionel,

could you please run the following command on the non responsive host?

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

Hi,

i've just upgraded one host to latest centos release. And after reboot ovirt said "Host CPU type is not compatible with Cluster Properties."
Looking on server i can see cpu is detected as skylake (cat /sys/devices/cpu/caps/pmu_name).

My CPU is Intel(R) Xeon(R) Gold 5220R CPU @ 2.20GHz so according to ark cascade lake server.
When i installed my new ovirt environment month agos, i configure cluster to be "secure Intel Cascade lake server family" and all sound goods.


So anyone can help me?


Environment :
OS : Centos 8.3 (for manager and host in error)
ovirt-engine 4.4.3.12-1.el8
Host with error : vdsm.x86_64  4.40.35.1-1.el8                               
Working Host : vdsm.x86_64  .40.26.3-1.el8                               


Maybe someone can help me? I don't know what to do, and does not want to try update another host  if it fail...

 Sorry if i post my message at wrong place.

Lionel Caignec.
