That will ensure the domain makes itself a big enough > memory map to increase its memory reservation. I still cannot create the "LowMem". Any suggestion? (I am running latest -testing tree) Here is my domain file: -- kernel =3D "/boot/vmlinuz-2.6-xenU" memory =3D 32 maxmem =3D 80 name =3D "tty" disk =3D [ 'file:/home/aq/myxen/rootfs.tty,hda1,w' ] root =3D "/dev/hda1 ro" extra =3D "mem=3D150" --- And here is domU's /proc/xen/balloon (immediately after creating domain): # cat /proc/xen/balloon=20 Current allocation: 32768 kB Requested target: 32768 kB Low-mem balloon: 0 kB High-mem balloon: 0 kB Xen hard limit: ??? kB Thank you, aq
