Nobody has answered the question of disk space usage. Let's say I have
five Windows 2008 servers. Right now they are using file based, growable
storage.
They each have a disk0 that is growable and partitioned like:
c: = 25gb
e: = 175gb (using round numbers)

Using clvm, would I be using 1TB of storage for these five domUs?

Of course -- you aren't gaining anything magic by using one disk technology over another unless you start talking about de-duplication. If you want the benefits of the "auto-growing sparse files" that you're currently using, consider allocating the amount of storage you actually need and growing it (via lvm) as you go.
