I'm a first time xen user, trying to get 2.0.3 up
and running for the first time. I've made some
progress, but xen doesn't seem to want to discover
my ide disks.
I built a xen kernel, starting from an existing, known-working
config file. I am running linux 2.6.10. The base distribution
is gentoo.
The hardware is a low end IBM server (xSeries 200).
The relevant grub config lines are:
title=IBM Gentoo Linux (bzImage)
root (hd0,0)
kernel /bzImage root=/dev/hda3
title=IBM Gentoo Linux (xen0)
root (hd0,0)
kernel /xen.gz dom0_mem=131072 noreboot com1=38400,8n1
module /vmlinuz-xen0 root=/dev/hda3 console=ttyS0,38400
The boot fails with this message when booting xen:
BIOS EDD facility v0.16 2004-Jun-25, 0 devices found
EDD information not available.
VFS: Cannot open root device "hda3" or unknown-block(0,0)
Please append a correct "root=" boot option
(the full serial log is available at
http://www.askneil.com/neil/xen/xenboot.txt
if anyone wants to see all the info...)
When EDD is running in a normal, non-xen kernel it reports:
BIOS EDD facility v0.16 2004-Jun-25, 1 devices found
Full dmesg output from the working, normal kernel is available at:
http://www.askneil.com/neil/xen/normalboot.txt
I'm sorry for bothering the list, but I'm trying to figure
out what I could be doing wrong that would interfere with
EDD, which just makes low level bios calls.
In addtion, the "normal" kernel probes all the ide busses
and connected drives; none of this output appears in the
xen boot listing (but this might just be a difference between
console and dmesg outputs...)
Thanks in advance for any help folks might have about
this...
