--------------------------------------------

Nice question Swamy garu, 
while adding the ZWPS, we have to definitely choose one hypervisor(KVM, VmWare) [assuming kvm is selected]. then the created zwps pool will be added to all the KVM hosts present in the zone.

                   id: 2
                 name: zwps1
                 uuid: f0802731-62fe-3a85-b81a-98ae47e845cf
            pool_type: NetworkFilesystem

zwps1 is a primary storage added with ZONE scope, while creating it I have choosen KVM as hypervisor.  At any time ZWPS will be set to only one type of Hypervisor.

> When we create an instance on vmware and try to resize the data disk , it gives an error saying "Can't resize a volume that has never been attached, not sure which hypervisor type. Recreate volume to resize"
> An InvalidParameterValueException is being thrown as the hypervisor is getting selected as none. The problem is when the storage is added at zone level. The cluster_id is getting selected as NULL in this case. If the storage is added at cluster level, things work fine. Please see the db query below: 
> mysql> SELECT c.hypervisor_type from volumes v, storage_pool s, cluster c where v.pool_id = s.id and s.cluster_id = c.id and v.id = 9;
> Empty set (0.00 sec)
> mysql> select * from storage_pool;

> Note: Marking it as a blocker as we can't test Disk Re-size feature on VmWare because of this.
