As you see, you restrict dom0 memory here quite massively, namely to
128MB, which is a  hard limit in this case.
This might be enough for machines with no bigger sevices, but
depending on what you run, this can become insufficient quite fast.
Run less services or give dom0 more memory - it seems like you have
more than enough to do the latter.

As for theory - not of much interest when having several GB at you
disposal: I am not sure what the minimum is to run the minmal set of
services on a dom0 - you probably don't want to abandom xend service
on this machine :)
