11:49 p.m.
I just tested adding a Centos 6.6 and Centos 7 host on a oVirt Cluster and
it is not possible:
Not possible to mix RHEL 6.x and 7.x hosts in one cluster. Tried adding
RHEL - 6 - 7.el6.centos.12.3 host to a cluster with RHEL - 7 -
1.1503.el7.centos.2.8 hosts.
Using the same data storage for multiple Clusters seems possible.
Thanks for all the help today,
Regards,
Paul
