Restore SAN snapshot to new VM

I need to test backup/recovery solution with SAN Compellent snapshots.  So I created a virtual network, and vm.
Now do I need to install a Windows on that VM or can I just restore right on with without the OS?
Please advice.

What you need to do is mount he snapshot as a different LUN (different signature) to your ESX host.  Since it's read only you can copy the VM folder to a different location on another datastore.  

From there you can add it to the inventory by browsing the VMX file.  Give it a different name in inventory and disconnect the nics or add the nics to a different vlan to ensure that it doesn't boot and cause name/ip conflicts.

Thanks Paul,
Does that mean I don't need to have an OS on the VM in order to restore from the snapshot?

Paul SolovyovskySenior IT AdvisorCommented:
That is correct from what I have seen at customer sites.  Since the snapshots copy the VM entirely (assumption) the OS is fully part of the snapshot.  Take a look on the website on how to resignature.

Got it.  I just did it and works.  I recovered an entire VM from the snap datastore.  

I have few more questions for you if you don't mind.  For the testing purposes do I need to create an individual isolated virtual switch?  If I select I_coped VM, would it generate new IP/MAC addresses and not cause any conflicts on production?  The host name I also assign different.

I would create an isolates vswitch so that no conflicts with production

I see.  If I do create an isolated vSwitch, then how will I transfer the snapshot from production network to the isolated vSwitch.  Will I be able to map the LUN it to the machine on isolated vSwitch?

Copy the snapshot as usual, since the VM is not running it's fine.  Once it's copied and registered in vCenter change the nic to the isolated vswitch and you're set.  The Lun is for the ESX hosts to access and not the VM so you're set.
