Check out the HOWTO etc. on user-mode-linux.sf.net. Basically, you just do:
ubd0=file1,file2
where file1 is the (possibly read-only) backing file, and file2 is the
copy-on-write data. The same backing file can be used with any number of
COW files, and a COW file is invalidated when the backing file is changed.
