Re: [Xen-users] domU startup Issue
I was somewhat lacking in details in the original post - It is an image,
and it can be mounted under loopback on dom0. Also the config file is
taken from my (working) Xen-2 setup, where prior to moving to Xen-3 it
did work OK. The domU kernel was made using the Dom0 config (minus the
privileged stuff).

Trying the ttylinux image:
config is:
kernel="/root/vmlinuz.domU"
memory=64
name="ttylinux"
nics = 1
ip = "192.168.0.4"
disk=['file:/root/ttylinux-xen,sda1,w']
root="/dev/sda1 ro"
booting gives (just the tail):
Floppy drive(s): fd0 is unknown type 15 (usb?), fd1 is unknown type 15
(usb?)
Failed to obtain physical IRQ 6
floppy0: no floppy controllers found

VFS: Cannot open root device "sda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on

What would be a good approach to take to track down this problem?
Thanks,
David.
The Image for the block device is this a filesystem ? Are you able to
mount it via the loop device under dom0 ?
Or is it a diskimage so you would to have it define as "sda" for the domU.
