[ovirt-users] Problem upgrading Host from 3.5 to 3.6 in Centos 6

[Scott Worthington]

For oVirt 3.6.x, these are the rules:

The ENGINE can be hosted on EL 6 or EL7
The HOSTS cannot be EL 6 -- must be EL 7+ or Fedora (I don't recall the
version)

How to upgrade your hosts:

* Put the oVirt EL 6 host into maintenance (that is, migrating or shutting
down all GUESTS from that host)
* Remove that Host from the cluster
* Wipe and install EL 7 onto that physical machine
* Bring that EL 7 machine into the cluster (via web gui Install)
* Repeat for all of the rest of the EL 6 hosts to complete the upgrade to
3.6.x

HOSTS on 3.5.x could either be EL 6 or EL 7, that is no longer the case
with oVirt 3.6.x
