Hi,

I started by setting memory=256 and mem=268435456, after booting I used

        $ xm balloon dev 128

to decrease. Then I have 256M available at the domU and I can decrease 
to any value that I like.

Starting domU with this memory settings gives me 128M initial memory but 
increasing the memory to any value between 128M and 256M show no 
reaction while "xm list" still shows me 233 M available... :(
