I''ve had some progress with this. I''ve found that an initrd is indeed required but I''ve been unable to build one that works on the Blade servers in domU. Can someone whos got this working on an IBM Blade advise how this is done? I keep getting ''unknown symbol errors'' when loading the modules in the initrd.

I struggled with this for while too. Got it going now though. Ok, I''m not on 100% identical hardware (it is HS20 but with AoE SAN), nor on Xen 3 (still running 2), but I think it''s more of an initrd issue than anything else. I found the Fedora and CentOS Xen manulas to be very helpful. Besides that, I wrote a howto for myself (http://www.armorica.net/index.php?id=57) that may be helpful. It deals with initrd (and what to leave out). Maybe it helps.

How do I do this for Xen? I''ve read aboutNot necessarily. domU initrd aren''t usually necessary as far as I know, but I have made several of them on the same distribution and version as you on that type of blade with commands like cd /lib/modules depmod 2.6.12.6-xenU mkinitrd --omit-scsi-modules /boot/initrd-2.6.12.6-xenU.img 2.6.12.6- xenU Can you post output from ''xm create -c'' for your domU as well as the domU configuration?

Kernel panic - not syncing: No init found. Try passing init= option to

(adding ''init=/sbin/init'' to extras in the config makes no
difference)
Note that no disks are found. This is why I think I need an initrd with the
modules for the SCSI control (LSI MPT Fusion).
Note also that after the panic, a ''xm list'' shows vm1 *not* in
a crashed
state, is this correct?
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 251 1 r----- 16.8
vm1 6 256 1 r----- 22.9
My config is:
kernel = "/boot/vmlinuz-2.6-xenU"
memory = 256
name = "vm1"
vcpus = 1
disk = [ ''phy:rootvg/xen_vm1,sda1,w'' ]
ip = "172.30.13.120"
netmask = "255.255.255.0"
gateway = "172.30.13.254"
hostname = "vm1"
root = "/dev/sda1 ro"
extra = "1"
on_crash = ''destroy''
I had a troll through the linux-2.6.12-xenU tree under xen-3.0.0 src and
found that the kernel config has PCI disabled, why is this?
Thanks
