It would be best, yes.
Here's what I use on xend-config.sxp

(dom0-cpus 1)
(dom0-min-mem 256)

and on grub's menu.lst

        kernel /xen.gz-2.6.18-128.el5 dom0_mem=512M dom0_vcpus_pin

This shows dom0 has 10G mem, which is good

This one shows python eats the memory. Which is veeeeery bad.
Now python is used for lots of things (xend among them), but in my
setup (where dom0 can only use 256-512M, and it only runs xend
service) it never acted up like that.

So the next question is what other programs on your dom0 uses python,
and look at it. You can disable them to see if it has any effects.
