[Xen-devel] error: (XEN) Not enough memory for DOM0 memory reservation.
Dear list,
I''m trying to get Xen working on a P3-600E with 320 MB RAM. (256+64)
It has suse linux 9.1 installed on it, and I tried to get xen running with
both the binary download from the xen pages and the suse xen packages
mentioned on this list some days ago.
Both ''install packages/kernels'' lead to the same error:
(XEN) Not enough memory for DOM0 memory reservation
Whereafter a poweroff/poweron is the only way ouy. (Machine doesn''t
have a
reset button, keyboard ctrl-alt-del does not respond)
The grub entries are:
title Xen 2.0 / XenLinux 2.6.9
kernel (hd0,1)/boot/xen.gz dom0_mem=131072 console=vga
module (hd0,1)/boot/vmlinuz-2.6.9-xen0 root=/dev/hda2 ro console=tty0
title Xen2
kernel (hd0,1)/boot/xen.gz dom0_mem=65536
module (hd0,1)/boot/vmlinuz-2.6.8-24.8-xen root=/dev/hda2 vga=0x314
splash=silent desktop resume=/dev/hda1 showopts
module (hd0,1)/boot/initrd-2.6.8-24.8-xen.gz
Lowering the dom0_mem anything between 8192 to 13300 works, but then the
kernel reboots during the boot process (for low values) and for higher
values the boot script processes get killed by oom_kill, who eventually
killes init too, kernel panics->reboot. Setting dom0_mem to 13313 or
anything bigger doesn''t work, produces the error "Not enough
memory for
DOM0 memory reservation".
What happens between 13300 and 13313 is untested, I think it has been
narrowed down sufficiently.
How can I solve this ? And/or what could I be doing wrong?
Thanks in advance,
Floris Martens

Re: [Xen-devel] error: (XEN) Not enough memory for DOM0 memory reservation.
When Xen boots, how much memory does it say it thinks your system has? What is the output from booting a native Linux kernel (in particular any lines very early that print the ''e820 map'')? -- Keir> Dear list, > > I''m trying to get Xen working on a P3-600E with 320 MB RAM.

It''s amazing that so many systems boot just fine without it. :-) I think the code is nicely self-contained and can be pulled out of Linux quite easily. -- Keir ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
