Hi, I gave up trying to restore a backup of my former hosted engine, I never managed to get engine and nodes communicate again and I need to go on. So I installed a new engine (let's try a dedicated one this time) and imported the storage domains successfully. After attaching and activating them, it seems to be ok and the first VMs I imported are now running fine. So I just have to redefine logical networks and configure them on the hosts, and it is ok ? Maybe final step will be turning dedicated engine to hosted, I don't know yet. Regards

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...
