dom0: advises range from reserving 128MB to 512MB if you arent running heavy 
        applications in dom0 (which should be moved into domUs).
domU: The kernel and applications running there handle memory as they do
        on usual servers, so size as usual here, mainly depending on the
        applications you will run.

256MB for dom0, rest split up for the 2 domU would be my guess.
