I have 4.3.3 on engine and hosts in 4.3.3 with plain CentOS, updated from 4.3.2 on 2/5.
Since the day after, 3/5, I get the event

Check for available updates on host ov200 was completed successfully with message 'found updates for packages ovirt-host'.

and also the icon at side of host in web admin gui.
But:
[root@ov200 ~]# yum update

[root@ov200 ~]# rpm -q ovirt-host
package ovirt-host is not installed
[root@ov200 ~]# 

yum search ovirt-host:

This is not an oVirt-NG host, but plain CentOS....

What to do? Do I have to install the ovirt-host package anyway?
Thanks in advance,
