Hi,
I have been going over and over this for about 8 hours straight, and I
can't see what I'm doing wrong.
I have just upgraded from Debian lenny to Squeeze, using their Xen.
When I was running lenny, I made my domUs with the debian tool
utility. It set the drives to sda*, instead of xvda*.
I know that with Xen 4, they like you to use xvda*, rather than sda*.
I'm cool with that, so I changed it in my configs, and even mounted
the domu in question, and set it correctly in /etc/fstab. However, it
still will not boot. In the console, I see it complain that it wasn't
able to assemble all the raid devices -- why that matters, I don't
know, Dom0 assembled them just fine, I don't understand why they would
need to be reassembled... but anyway... Here is what I am getting at
the xm console:
dom0box:/etc/xen/configs# xm console domubox

- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/xvda2 does not exist. Dropping to a shell!

Here is my config:

memory = '512'

extra = "console=hvc0 xencons=tty"
extra="clocksource=jiffies
I have checked (on Dom0) my /etc/mdadm/mdadm.conf file, and the UUIDs
are correct. I have been looking at scores of posts on the list and
elsewhere for help, and one had stated that changing level=raidx to
level=x, but that didn't help either.
Interestingly enough, my hvm domus DO start up fine. They were made
using xvda* instead of sda*... I don't know which part here is
significant (hvm or being made with xvda).
I also noticed that the debian wiki says: "If your domU kernel happens
to miss support for the xvda* disk devices (the xen-blkfront driver),
use the --scsi option that makes the VM use normal SCSI HD names like
sda*. "
However, they do not say where to use the --scsi... the xm command
doesn't accept it... so what else is there?
I've been over this a million times now, I just can't see what I'm missing.
Can someone please give me a hand here?
Thank you.
