Do you think that I can import the SDs in my new Data Center without any risk to destroy the VMs inside them ?? Thank you for your advice.

So anyway I have to go further and import the storage domain passing the alert message. Am I right ?

Is there any command to verify if the storage domain contains VMs or not ?
You can execute this on one of your hosts. # vdsClient -s 0 getStorageDomainsList to get storage domain list, than # vdsClient -s 0 getStorageDomainInfo <domain UUID> for each of them till you identify the domain you are looking for. You can also find there the pool UUID. Than # vdsClient -s 0 getVmsList <pool UUID> <domain UUID> To get the list of VMs on that storage.

To complete my previous post, if this storage domain doesn't contain VM, but just Disks attached to other VMs from other Storage Domain. 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.
