Can you explain more about "booted with 256M and then decreased to 128M"?
Do you mean you add "mem=268435456" as the kernel command line parameter
as well as a line "memory=128" in domain "dev"'s configuration file before
you create the "dev" domain? In another word, the "dev" domain's config

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... :(
