[Xen-devel] Ongoing Grub Problems

[Sam Johnston <samjie@xxxxxxxxx>]

Good evening all,

I recently wrote to the list about a problem with grub: 'Error 28:
Selected item cannot fit into memory'. I am still having the same
issue, atlhough I have done more troubleshooting since then. I have
rebuilt the offending machine from scratch with Debian stable and
installed the requisite packages from testing:

gcc            3.3.5-3        The GNU C compiler
bridge-utils   0.9.5-2        Utilities for configuring the Linux 2.4 brid

python-dev     2.3.5-1        Header files and a static library for Python
python-twisted 1.3.0-8        Event-based framework for internet applicati

libcurl3       7.13.1-2       Multi-protocol file transfer library, now wi
libcurl3-dev   7.13.1-2       Development files and documentation for libc

I still get a similar error:

grub> kernel /boot/xen.gz
[Multiboot-elf, <0x4028d000:0x3ef5c:0x360a4>(bad)

Error 28: Selected item cannot fit into memory

I've also tried to install the xen-2.0.5 binaries on my local
workstation - a Dell Optiplex GX280, but get the same thing:

grub> kernel /boot/xen.gz
[Multiboot-elf, <0xb7b69000:0x3ef3c:0x360c4>(bad)

Error 28: Selected item cannot fit into memory

The following is the bug report I submitted against grub figuring it
may be a problem with multiboot, but the more troubleshooting I do,
the more I believe it to be a compatibility issue or a problem with
Xen itself.

I hope someone can provide some more information about what's going
wrong as I'd really rather use Xen than one of the alternatives.

Thanks,

Sam

I am unable to setup xen 2.0.5
(http://www.cl.cam.ac.uk/Research/SRG/netos/xen/) on a colo Athlon
2000+ box per the following error. The binaries were downloaded from
http://www.cl.cam.ac.uk/Research/SRG/netos/xen/downloads/xen-2.0.5-install.tgz
and I have tried both with xen.gz and xen (gunzip xen.gz).

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)

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>

If I compile a more recent version (0.96 and CVS20050331) I get a
Segmentation Fault:

GNU GRUB version 0.96 (640K lower / 3072K upper memory)

[ Minimal BASH-like line editing is supported. For the first word, TAB

completions of a device/filename. ]

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

grub> kernel /boot/xen.gzSegmentation fault

The partition (hd0,0) is an ext3 partition currently mounted rw on an
80Gb IDE drive.

I have not yet recompiled xen from scratch but do not believe it to be
a problem with xen itself as this is a public release that is known to
work elsewhere.

I do not have access to the physical hardware as it is in another
country. Perhaps lspci is useful:
