[Xen-devel] RAMDISK-Boot: Not enough RAM for domain 0 allocation.

["viets@xxxxxxx" <viets@xxxxxxx>]

Hello,
I'm trying to boot xen-3.3 from network with linux on a ramdisk, but
this fails with the output below:

this are my boot-settings:

default xen-linux
prompt 1
timeout 10

label xen-linux
  kernel mboot.c32
  append xen-3.3.0.gz noreboot dom0_mem=2097152 console=com2

After some researching, I've found this
thread(http://lists.xensource.com/archives/html/xen-devel/2008-08/msg00518.html),
but the solution doesn't work for me.

Thanks in advance
