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.
