Oh weird!! I think I may have just figured out what it was, so
dom0_mem=512M in grub, and dom0-min-mem=512 in xend-config, balloon on
or off didnt seem to matter, but anyway...

On a fresh reboot domain-0 would be using ALL the memory except for
like 130 megs or so out of 4 gigs. So every time i tried to start a
guest it would complain about not enough memory. I thought maybe it
was suppose to take memory away from its "pool" of used memory or
something and use for the guest.

So, I just rebooted again keeping dom0_mem=512M and set balloon to no
and dom0-min-mem=192 and then "xm mem-set Domain-0 512" and I can see
my available memory go up to 3 gigs where it should be.

Any reason why it would start off sucking up all the ram? Am I doing
something wrong? Is there a way to say on a reboot give domain-0 512
megs of ram and thats it? I would have thought that by turning
ballooning OFF that this would be the effect but apparently not?
