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

[root@vps auto]# xm create ispbrasil
Using config file "./ispbrasil".
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?
