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

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?
