problem

Cloudstack 4.21.0.0 + VMware 8u3g + vSAN + Veeam 12 environment.

When trying to create a new instance from an existing backup, an error occurs because the datastore cannot be found. The datastore lookup is using the CloudStack UUID instead of the volume name.

$ds = Find-VBRViDatastore -Server:$server -Name "0f2b59684453331eb366a6d7036bae96"

Find-VBRViDatastore doesnt accept uuid, it needs vmware volume name
