this is due to the cluster cpu type, you should select the right architecture for the hosts cpu. each cluster must have similar cpu types.

Hello everyone!

I'm trying to configure a Centos 7 machine to serve as a host, but I'm not successful. I already get the message "Host Host1 moved to Non-Operational state as host CPU type is not supported in this cluster compatibility version or is not supported at all".

Here the commands that I used to configure the host:

$ sudo yum install vdsm
$ sudo yum install centos-release-ovirt41
$ sudo systemctl disable firewalld
$ sudo systemctl disable NetworkManager
$ sudo vim /etc/selinux/config

...
SELINUX=permissive
... 

$ sudo vim /etc/hosts

...
10.142.0.3 ovirthost-1.c.sharp-quest-137201.internal ovirthost-1  # Added by Google
10.142.0.2 ovirtengine-1.c.sharp-quest-137201.internal ovirtengine-1
...

Att,
