[ovirt-users] Switch from Fedora 20 to CentOS 7.1

Hi Soeren,

oVirt Clusters support one host distribution (all hosts must be of the same distribution).
If the cluster is empty at one point, you can add a host of a different distribution than the cluster occupied before.
But there can't be two type of distributions at the same time in one cluster.

Regards,
Vered
