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.

Ok great, I can see the different storage that I want to import, but I can't see the VMs on the un-connected pool.
So anyway I have to go further and import the storage domain passing the alert message.
Am I right ?
No other way to see the VMs in SD :

> 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.
