i'm running xen 2.0 on a bi celeron 400 and i've dedicted 32 Mo to dom0
mat@zeus:/$ free
             total       used       free     shared    buffers     cached
Mem:         32768      31888        880          0          0       9552
-/+ buffers/cache:      22336      10432
Swap:       506008       8828     497180
And i'm forecasting to reduce it maybe to 24 Mo 
The biggest process in memory are xend + xm (because i'm doing a xm console

I've slightly modified the dom0 kernel to get unusefull parts out but i
think the reduction isn't huge (1 or 2 Mo)

i'm running a 2.4.27 kernel
