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.

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. _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://apac01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt... oVirt Code of Conduct: https://apac01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt...
