[ovirt-users] hosted engine setup on second host fails

Wed Sep 24 12:13:57 EDT 2014

Seems we should consider not adding the host if already there. Please open a bug.
Though I really hope in 3.6 to see this done from the gui

Davids hint was the solution. I had the ovirt hosts already added to the
cluster and tried to do the hosted-engine-ha setup on them.

After removing the hosts from the cluster and putting the data domain to
maintenance mode I was able to deploy an all other nodes. I now have a
HA'd hosted engine. Which can also be migrated \o/

Maybe that is something that could be stated in the documentation more
clearly?

Unfortunately now I have a new problem. The agents crash rapidly after
startup. The error is the following:
(/var/log/ovirt-hosted-engine-ha/agent.log)

AttributeError: 'NoneType' object has no attribute 'iteritems'

And the whole output here - The agents have been started and I tried a
migration of the hosted engine from ovirt host 1 to host 2 which
succeeded. But the agents crashed afterwards:
