i tried to expand the memory from DOmU on the fly, without need to
reboot the guest.

actually i have in my setup:

memory = 128
maxmem = "512"

i can shrink the memory from Dom-0 to get enough free to assign it to
the VM. After that i set the memory from Dom-U to the "maxmem" (512MB)
and i can see it in xentop, that it was working, but in the Dom-U i see
only the 128MB. Only after a reboot the VM get the full 512MB.

What is also strange, if i shrink the mem of dom-0 and assign it do
Dom-U, "xm info" shows the complete free memory, which i assigned to the
guest. Strange, isn't it?

What i want is to expand the memory on the fly, without the needing of a
reboot and i swear that it _was_ working with extra = "mem=512M", but
now i don't get it working again :-/
