Before running that, run something like:

xm balloon 0 128

That basically balloons down memory for the host OS (dom0) to 128MB of
ram. What happens with Xen nowadays is that it allocates full amounts of
system ram to the dom0, and this means it can't allocate anything at all
for the guest

128 is just an arbritary number. It can be higher or lower depending on
your system ram and how much you want to give the guest os

Said error message will disappear if you balloon down the memory then
run xm create -c rawhide

You'll want more than 9MB of RAM for the guest. Really

While Xen is enabled there, there are console issues I think that will
somehow not allow you to get to a login console (or at least that was
the case for me)
