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

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.
