> Root Cause: CloudPlatform creates a SR on each host, which points to the template location
on the secondary storage (secondary_Storage/template/tmpl/<account_id>/<template_id>).
This causes the database unique constraint violation when each XenServer tries to scan the
SR created on each host. The host that scans the SR last, throws the exception because VDI
was recognized already from the SR scan of the first host.
