Update:

The OVF_STORE volume will contain the engine VM description in a format that the engine can easily handle.
It will be created by the engine when:
- it imported the hosted-engine storage domain
- the engineVM is visible
- the datacenter is up (you need at least one additional regular storage domain)

Please make sure that all these conditions are met.

If the OVF_STORE is not there or it's not accessible, ovirt-ha-agent will fallback to the initial vm.conf from deployment time. You see a warning since we are failing back to an initial status and this can temporary override your latest customization to the engine VM configuration.


1. I was able to remove the warnirngs about the not found ovf / vm.conf by commenting the conf_volume_UUID, conf_image_UUID entries in the hosted-engine.conf. After a restart of the ovirt-ha-agent the errors were gone. ( I believe this is not a permanent solution ).

Please revert it.
 

2. This morning I noticed the warning in the event log.
"The Hosted Engine Storage Domain doesn't exist. It should be imported into the setup."

It's just a side effect of your point 1, please revert it.
 

Any help would be appreciated.

I have been upgrading our ovirt hosts to el7 to be able to run version 3.6.
When deploying a new host have problems with the shared OVF storage config part.

1. I get an error during deploy:

[ INFO  ] Stage: Setup validation
[ ERROR ] Failed to execute stage 'Setup validation': failed to read metadata: [Errno 2] No such file or directory: '/rhev/data-center/mnt/[NFS3_SHARE]/88b69eba-ef4f-4dbe-ba53-20dadd424d0e/ha_agent/hosted-engine.metadata'
[ INFO  ] Stage: Clean up

It seems the symlink of hosted-engine.metadata is missing.
So I added manually the /var/run/vdsm/storage folder with subfolder 88b69eba-ef4f-4dbe-ba53-20dadd424d0e and symlinks.
Then I reran the hosted-engine deploy and this time all went well.

2. Now when the host is installed I notice the following in the logs

....

So at this point I was a bit stuck.
I removed complete ovirt36 release and installed ovirt35 for the hosted engine deploy.

This time all went without any problem directly.
From there I retried upgrade and same problems again.

I run ovirt hosted-engine on nfs3. I did found https://bugzilla.redhat.com/show_bug.cgi?id=1159314 
I added no_subtree_check and tried deploy again, but again without luck.

I believe the hosted engine configs are not being migrated to the shared storage. And my problem has todo with http://www.ovirt.org/Features/Hosted_Engine_configuration_on_shared_storage

And found  /etc/ovirt-hosted-engine/hosted-engine.conf, 
conf_volume_UUID, conf_image_UUID
 

Hosts run el7
Hosted engine runs el6
Hosted engine storage is through NFS3

Can I import the hosted engine storage in to engine ( in web interface )?
Or how can I create or trigger manually the OVF store the logs complain about?
