Thanks Martin. The hosts are all part of the same cluster.

I get these errors in the engine.log on the engine:

The sanlock.log reports conflicts on that same host, and a different
error on the other hosts, not sure if they are related.

And this in the /var/log/ovirt-hosted-engine-ha/agent log on the host
which I deployed the hosted engine VM on:

MainThread::ERROR::2017-06-19
13:09:49,743::ovf_store::124::ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore::(getEngineVMOVF)
Unable to extract HEVM OVF

13:09:49,743::config::445::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config::(_get_vm_conf_content_from_ovf_store)
Failed extracting VM OVF from the OVF_STORE volume, falling back to
initial vm.conf

I've seen some of these issues reported in bugzilla, but they were for
older versions of oVirt (and appear to be resolved).

I will install that package on the other two hosts, for which I will
put them in maintenance as vdsm is installed as an upgrade. I guess
restarting vdsm is a good idea after that?

Thanks,

Campbell
