How to set a VDI as immutable?

[mvanhorn]

Host OS is Mac OS X (will eventually be Linux)
Guest OS is WIndows XP

I'm getting a vdi set up with the software we need, and then it is going to get copied to multiple workstations for others to use. Once it's all set up, how do we mark it as immutable? I have read about immutable images, but I haven't found docs that tell how to actually set up such a thing.

Also, is there a way to make a vdi larger? This is easy to do with Parallels (on the Mac), but since these aren't going on Macs, we can't use Parallels.

Thanks!
