[Xen-devel] grub Error 28: Selected item cannot fit into memory

[Sam Johnston <samjie@xxxxxxxxx>]

Good evening all,

I've all but finished installing Xen 2.0.5, XenLinux 2.6.10 and Debian
GNU/Linux 3.0r4 into /boot on a colo box currently (and temporarily)
running CentOS. I've chrooted into the debian install (chroot /boot
/bin/bash) and was able to set everything up, install requisite
packages, install xen, etc.

Now I'm at the last step and I've run into problems. When I point grub
at xen.gz it complains loudly:

   GNU GRUB  version 0.95  (640K lower / 3072K upper memory)

[ Minimal BASH-like line editing is supported.  For the first word, TAB
  lists possible command completions.  Anywhere else TAB lists the possible
  completions of a device/filename. ]

grub> root (hd0,0)
Filesystem type is ext2fs, partition type 0x83

grub> kernel /boot/xen.gz dom0_mem=131072 console=vga
  [Multiboot-elf, <0xb72f2000:0x3ef3c:0x360c4>(bad)

Error 28: Selected item cannot fit into memory

grub>

Does anyone have any ideas about how to solve this one? I have set up
the menu.lst but would rather not have to call on a console jockey
should things go awry as it's a colo box in another country. The
underlying CentOS 3.4 is using grub 0.93 (the new / is currently
polluted with the current running kernel and grub directory as it's
still mounted as /boot for the time being - it will be / when all this
works). I'd have tried recompiling were I not short on space - it
would be nice if that were all I needed to do. It's an Athlon 2000+
with 512Mb RAM and an 80Gb IDE disk, by the way, per the following
/proc contents. Let me know if there's anything else you need to know.

Kind regards,

Sam
