I would really like something like this scenario.. I have many VMs. They take alot of space. I have a base image, with Windows XP, IE7, Opera, Firefox and some other weird 3rd party application. When I need to make a new environment I would have to copy this .vhd and build on that. If I could use this base for every image, and have a small "image" with just the diff to the new image, I would save alot of space. Ie my base image is about 2.2 GB, and the "add-on" image is 300 MB. This means that if I have 3 sets like this, it would take 7.5 GB today. With this strategy implementet it would take 3.1 GB. PS. How do I get CRLF/HTML line break in here? -jr
Maybe someone should take a good look at the Virtual Disk Wizard...

All you have to do is create a differencing disk (using the Virtual Disk Wizard), specify a base image, and go. Do note that this is separate and apart from Undo disks, this doesn't give you the option of merging your changes every time you close Virtual PC.
