In case of a total failure of the hosted engine VM, it is recommended to

have to do this very soon.
But is there some kind of "plug and play" features, able to rebuild
configuration by browsing storage domains, if the restore process doesn't
It's called "Import Storage Domain" in oVirt.
Something like identifying VMs and their snapshots in the subdirectories,
and the guess what is linked to what, ... ?
I have a few machines but if I have to rebuild all the engine setup and
content, I would like to be able to identify resources easily.
A few times ago, I was doing some experiments with XenServer and
destroyed/recreated some setup items : I ended with a lot of oprhan
resources, and it was a mess to reattach snapshots to their respective VMs.
So if oVirt is more helpful in that way ...
If you try this:
1. Try first on a test setup, as always
2. Make sure to _not_ import the hosted-storage domain, the one used to
host the hosted-engine VM.
3. So: setup a new hosted-engine system, then import your _other_ storage
domains. Ideally make sure the old hosted storage is not accessible to
the new system, so that the new engine does not try to import it accidentally.
4. If you do try to import, for testing, the old hosted-storage, would be
interesting if you share the results...
