Can you specify "depending on what the server is
doing"?
I'm running databases in 2 of the domains, one is just
testing and one
for development (compiling etc.)
When does your dom0 need 1GB and on the other hand 2GB? I
would suggest
the dom0 should always use as less memory as possible?

Normally I specify 1 GB, most of my servers have more than
12 GB of
memory.  It is overkill at 1 GB but would rather fall on the
side of
safe.  This is a base dom0 doing nothing but running XEN and
domUs.  If
dom0 is also doing other tasks I allocate addition memory to
ensure no
memory contention.  You could run with 512mb for dom0, but
you would
have to be confident in what dom0 is doing, and that things
like
automatic updates to the OS do not cause problems.
