Linux/Xen/DomU/Devuan/Devuan Jessie
Devuan Jessie
Start this process on a existing Devuan system. You will need to have the Devuan patched version of debootstrap installed.
Create a empty image file and format it with ext3.
dd if=/dev/zero of=devuan_jessie.img bs=1M count=1 seek=1024 mkfs.ext3 devuan_jessie.img
Create a directory to mount the image on. Using '/mnt/img' for this example.
mkdir /mnt/img mount -oloop devuan_jessie.img /mnt/img
Start the debootstrap process.
debootstrap --variant=minbase jessie /mnt/img http://auto.mirror.devuan.org/merged/
Once that completes, copy your existing /etc/apt/sources.list to the new image so we can run updates.
cp /etc/apt/sources.list /mnt/img/etc/apt/
Here is a basic sources.list
deb http://auto.mirror.devuan.org/merged jessie main deb http://auto.mirror.devuan.org/merged jessie-updates main deb http://auto.mirror.devuan.org/merged jessie-security main
Mount the necessary system files so that we can enter the new root filesystem with chroot.
mount --bind /dev /mnt/img/dev mount --bind /dev/pts /mnt/img/dev/pts mount -t proc proc /mnt/img/proc mount -t sysfs sys /mnt/img/sys chroot /mnt/img
Run updates and install a language pack.
apt-get update apt-get upgrade
Configure the system timezone.
dpkg-reconfigure tzdata
Install the kernel image, SSH server and the full version of vim
apt-get install linux-image-`dpkg --print-architecture` apt-get install openssh-server apt-get install vim
To use the Xen console 'xm console (domU)' you need to setup a tty on /dev/hvc0. Edit /etc/inittab and add this line.
co:2345:respawn:/sbin/getty 38400 hvc0
The default udev rules for Devuan ignore Xen generated MAC addresses so you won't get a '/etc/udev/rules.d/70-persistent-net.rules' This causes your network interfaces not to come up.
Edit '/lib/udev/rules.d/75-persistent-net-generator.rules' and comment these lines. Here's the changes in patch/diff format.

Final Cleanup
Set a hostname.
Remove /etc/udev/rules.d/70-persistent-net.rules so that network comes up clean when the image is booted for the first time.
Remove SSH host keys so that new ones get generated on first boot.
Set a root password
echo 'devuan' > /etc/hostname
rm /etc/udev/rules.d/70-persistent-net.rules
rm /etc/ssh/ssh_host_*
passwd root
