Hello Ernst and Marcin,
thank-you both for your tips.

Unfortunately sarge's mkinitrd requires devfs for MD+LVM support, and
the kernels supported by xen do not have devfs any more. I work that
around by sticking the attached script to /etc/mkinitrd/scripts/
before
running mkinitrd.
I tried running mkinitrd both before and after placing this script
in /etc/mkinitrd/scripts:
#!/bin/bash
# make a lvm LV node here
perl -pi -e 's,^vgchange,mount_tmpfs /devfs\nmkdir /devfs/mapper
\nmknod /dev/mapper/group1-dom0slash b 253 0\nvgchange,' $INITRDDIR/
script
# prevent umounting the tmp dir with the node (would happen before
mounting, ruining the above mknod)
perl -pi -e 's,^,#, if /devfs/' $INITRDDIR/sbin/init
Each time I got the same results:
dom0a:~# mkinitrd -o /boot/initrd.img-xen-2.6.12.6-xen0 2.6.12.6-xen0
File descriptor 3 left open
File descriptor 4 left open

Finding all volume groups

/usr/sbin/mkinitrd: /dev/mapper/group1-dom0slash: Kernel does not
support LVM
I think the error message is pretty clear, i.e. the kernel supplied
with Xen 3.0.1 does not support LVM.
I guess I have two options, either stop using LVM or build my own
kernel?
Cheers,
Mark.
