Is there any command to verify if the storage domain contains VMs or not ?

How can I check it before breaking the rest of my data importing other SD ??? Thanks No I don't see any VM images, that the big problem...
Ok, I've done that action, but after I don't any "Import VMs" and "Import Templates" tabs.... What's happening ???? Alain
You don't have to explicitly re-import each VM. You should find your storage domain with all the preexisting VM images.

Hi, The plan using import Domain seems to be OK, but when I finalize the importation of a Data/iScsi I have this alert :
Storage Domain(s) are already attached to a Data Center. Approving this operation might cause data corruption if both Data Centers are active.
How can I detach this domain to a non visible old Data Center ?? Can I pass this alert without data lost ?
If the old engine is no more active and the new one is using a new database and not an imported one you are safe to proceed.
Thanks Alain

I plan to reinstall on a cloned VM from the original one, I have cleaned the previous version, and made an engine-setup. So I have backups from the previous Manager, I can backup to the new one. But, reading the overt-engine-backup, it seems to be possible only before doing engine-setup. Is that right or may I launch a backup after an engine-setup ? An engine-clean is enough to use engine-backup ?
Thanks

Hi I want to reinstall a new clean oVirt Manager, and I have a question : If I install a new manager, do I recover the datacenter and all the Vms installed in it without any lost of data ? What is the best practice to do this safely ? Thank you for your help Alain
Are you planning to install on a new host/VM?
You have basically two alternatives: A. backup the DB and restore it on the new engine as described here: http://www.ovirt.org/Ovirt-engine-backup
B. Start from scratch with a new engine on a new DB and re-import existing storage domains: http://www.ovirt.org/Features/ImportStorageDomain
Option B involves a lot of manual steps but it could be also used as a disaster recovery flow when the DB is for any reasons lost or corrupted.
