Base image or "Linked clones" as vmware calls it. Possble on PVE?

Hi guys,

I have a test lab for Windows Server 2003 and 2008 that i Need to setup and need several Windows VMs based off a single image. I was reading how vmware and xenserver offer this and how to use sysprep to setup windows to have a unique secure ID.

Now, does PVE 2.0 allow the creation of linked clones, or is there a way that I can create a single VM at first, install and update everything, then create either storage pointers to the original image and have differentiating disks created for the child VMs off this image?

Thanks!
