I usually run UML with 32M of RAM and they don't use it all often (I wouldn't try 16M, but 24M may work); then it comes swap space. Additionally there's the space which is used to cache the UBD, but that can be reduced a bit when you use a common backing file with different COW files on top of it (if the COW file is little, the host can easy notice the content sharing). -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
