[Xen-users] question about xm mem-set

[tgh <tianguanhua@xxxxxxxxxx>]

hi
I use xen-3.0.3 ,and when I try to xm mem-set domU ,it does not work as
I expected

I boot up the domU with the config file mem=256
then I xm mem-set domU 128 ,and it works well ,
that is, xm list shows domU's mem =128 and in the domU,/proc/meminfo is 128M

but when I xm mem-set domU 512, it does not work well
though the xm list shows domU's mem =512 , but in the domU
,/proc/meminfo is 256M ,not 512M


does xm mem-set can not expand domU's memsize beyond its boot-size? or
what should I do ?

could you help me
Thanks in advance
