RAMDISK-Boot: Not enough RAM for domain 0 allocation.

RAMDISK-Boot: Not enough RAM for domain 0 allocation.

[viets]

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

How big is the ramdisk image, uncompressed?

Hello,

the image has a size of 1048576 kilobytes uncompressed.

Re: RAMDISK-Boot: Not enough RAM for domain 0 allocation.

[Keir Fraser]

Xen wants to allocate smallest power-of-two sized memory block which will
fit both kernel and initrd. This will be 2GB on your system, and there is no
such 2GB aligned block. Either this restriction of the domain builder needs
to be lifted (a bit of a pain and not really on anyone's todo list), or you
could just reduce your initrd size by 100MB and cross your fingers -- it's
likely that Xen will be able to find an aligned 1GB memory block.
