Re: [Xen-users] Xen 3.0.2 on Dell 1850 - unable to recognize root fs on
Thanks David!
I implemented your suggestion and, while I was at it, added md, raid0
and raid1 statically. I decided to add LVM to the raid partitions and
so built that in statically as well. So, here's what the kernel
config looks like:
#
# Multi-device support (RAID and LVM)
#
CONFIG_MD=y
CONFIG_BLK_DEV_MD=y
# CONFIG_MD_LINEAR is not set
CONFIG_MD_RAID0=y
CONFIG_MD_RAID1=y
# CONFIG_MD_RAID10 is not set
# CONFIG_MD_RAID5 is not set
# CONFIG_MD_RAID6 is not set
# CONFIG_MD_MULTIPATH is not set
# CONFIG_MD_FAULTY is not set
CONFIG_BLK_DEV_DM=y
# CONFIG_DM_CRYPT is not set
CONFIG_DM_SNAPSHOT=y
CONFIG_DM_MIRROR=y
# CONFIG_DM_ZERO is not set
# CONFIG_DM_MULTIPATH is not set
It then recognized the LVs fine, but I ran into a another different
problem. It could not open the initial console. After searching the
net, someone mentioned that udev must be mounted before a console can
be opened. So I did:
# mkinitrd --builtin=mptbase --builtin=mptscsih --builtin=raid0 --
builtin=raid1 /boot/initrd-2.6.16-xen0.img 2.6.16-xen0
and added the following to my menu.lst file:
module /initrd-2.6.16-xen0.img
and everything booted up fine!
Thanks again.

Make sure you have SCSI support built in:
# SCSI device support
#
CONFIG_RAID_ATTRS=m
CONFIG_SCSI=y
CONFIG_SCSI_PROC_FS=y
#
# SCSI support type (disk, tape, CD-ROM)
#
CONFIG_BLK_DEV_SD=y
You may also need MPT support:
CONFIG_FUSION=y
CONFIG_FUSION_SPI=y

I'm trying to run Xen 3.0.2 on a Dell 1850 that has the following
specs:
2 x dual core 2.8Ghz Xeons
LSI something or rather SCSI controller
2GB of RAM
2 x 73GB Ultra SCSI 320 Maxtor drives
I have the two hard drives in a RAID 1 configuration, where /dev/
md2 is the root partition.
my grub.conf/menu.lst file looks like this:
title Xen 3.0
kernel /xen.gz dom0_mem=65536
module /vmlinuz-2.6-xen root=/dev/md2 ro console=tty0
No matter what I try, it always does a kernel panic complaining
about md2. So rather than using the binary files, I compiled a
custom kernel with options for SCSI, RAID0, RAID1 and drivers for
LSI SCSI stuff built in as static, rather than modules.
Same thing. The boot is always interrupted by the kernel panic
complaining about md2. Has someone gotten Xen to run on such a
setup? If so, can you offer any pointers?
