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.

Hello all,

We recently had a network event where we lost access to our storage for a period of time. The Cluster basically shut down all our VM's and in the process we had three HV's that went offline and would not communicate properly with the cluster.

We have since completely reinstalled CentOS on the hosts and attempted to install them into the cluster with no joy. We've gotten to the point where we generally get an error message in the web gui:

Which EL release and which oVirt release are you using? My guess would be latest EL, with an older oVirt? 
Y. 


Stage: Misc Configuration
Host hv-ausa-02 installation failed. Command returned failure code 1 during SSH session 'root@10.1.90.154'.

the following is what we are seeing in the messages log:

Can someone point me in the right direction to resolve this - it seems to be a SASL issue perhaps?
