Hi,
So, the time has come with the Lenny release for me to consider
upgrading my VPS from etch. I remember a thread a few months ago where
it was mentioned that Lenny's kernel had problems acting as a Xen domU.
Is this still the case? Any other gotchas that I should be aware of?

In January I upgraded all the hypervisors and so you shouldn't have
any issues.
I would advise keeping a known working grub.conf with an Etch kernel
in it as one of the boot options, though, to begin with.
A Lenny boot stanza needs to look like this:
title Debian GNU/Linux, kernel 2.6.26-1-xen-686
root (hd0,0)
kernel /boot/vmlinuz-2.6.26-1-xen-686
root=UUID=2ffd4d00-8acb-4f0d-b188-a612392c3678 console=hvc0 ro
initrd /boot/initrd.img-2.6.26-1-xen-686
Note the "console=hvc0"
Likewise in /etc/inittab you need:
co:2345:respawn:/sbin/getty 38400 hvc0
Also "hvc0" in /etc/securetty, but I think the normal package
upgrade does that.
And finally make sure udev is installed, but I think it is on Etch
so should remain there.
Cheers,
Andy

Hi,
Thanks for the tips. Most of the way there, one problem remains [see below].

Yeah, this was there.

It was and still is.
Now the problem I'm having is with configuring the new kernel (this was
the only dpkg issue with the upgrade, not bad). Here's the output:

I tried to create a device.map but it didn't change anything. This looks
a lot like [0], so I guess this is a genuine bug.
Any ideas? I guess I should still be fine with etch's kernel, but I'd
obviously like to have Lenny's one if possible.

Ironically I was just having the same issue; after googling it was in
fact an old post by Andy that sorted things out for me :D

Thanks Mat, doing that has enabled me to install the 2.6.25 kernel
without errors
No I just need the courage to do a reboot ;-)

Good find, thanks! I just had to change xvda to sda but it all worked.
Forwarding it to the Debian bug for information too (the link above will
show you a method to work around this error. Maybe it can be
incorporated into the packaging somehow?)
