I have 2 gb of memory on this machine, and in my
domU config I have set mem=32

Error: I need 32768 KiB, but
dom0_min_mem is 200704 and shrinking to 200704 KiB would leave only -167936 KiB
free.

So, it looks like you've got 256MB given to Dom0 and abouot 512MB of
RAM
total in the machine.
I think you may have problems fitting a
256MB Dom0, Xen Hypevisor and a
256MB guest in 512MB. Perhaps you can reduce
the Dom0 memory by some
20-30MB and get it to fit?
