[ovirt-users] Unable to add Hosts to Cluster

Fri Feb 16 21:14:05 UTC 2018

We are using CentOS Linux release 7.0.1406 (Core) and  oVirt Engine
Version: 3.5.0.1-1.el6

We have four other hosts that are running this same configuration already.
I took one host out of the cluster (forcefully) that was working and now it
will not add back in either - throwing the same SASL error.

We are looking at downgrading libvirt as I've seen that somewhere else - is
there another version of RH I should be trying? I have a host I can put it
on.
