Install OpenSUSE

Make sure you're in pvh mode

xen-shell> virtmode pvh

Boot rescue VM and log in

xen-shell> rescue

After a while you'll be presented with a login prompt. The password is auto-generated and should be printed a few lines above the prompt. Once you're logged in, become root: 

user@rescue:~$ sudo -i
root@rescue:~#

Install required utilities into rescue VM

  1. apt update
  2. apt install rpm zypper curl btrfs-progs zstd parted

Set up partitions on disk

  1. wipe existing block devices `for d in a b; do wipefs -a /dev/xvd${d}; done`
  2. create partitions
    1. parted -s /dev/xvda mklabel gpt mkpart root btrfs 0% 100%
    2. parted -s /dev/xvda set 1 boot on
    3. parted -s /dev/xvdb mklabel gpt mkpart swap linux-swap 0% 100%
    4. mkfs.btrfs /dev/xvda1
    5. mkswap -L SWAP /dev/xvdb1
  3. mkdir -vp /target && mount -v /dev/xvda1 /target

Copy in resolv.conf

  1. cp -v /etc/resolv.conf /target/etc/

Set up Zypper repoes

  1. set up repo files
    1. mkdir -p /target/etc/zypp/repos.d/
    2. cat <<-EOF > /target/etc/zypp/repos.d/repo-oss.repo

[repo-oss] name=Main Repository enabled=1 autorefresh=1 baseurl=http://download.opensuse.org/distribution/leap/\$releasever/repo/oss/ path=/ type=rpm-md keeppackages=0 EOF

Install Zypper

  1. run `zypper --releasever=15.3 -R /target install zypper`
    1. trust the key
    2. say yes to everything else

Mount chroot

mount -v --bind /dev /target/dev

mount -v --bind /dev /target/dev

mount -v -t proc procfs /target/proc

mount -v -t sysfs sysfs /target/sys

chroot /target /bin/bash

zypper --releasever=15.3 install openSUSE-release lsb grub2 dracut-tools wicked

cat > /etc/default/grub << EOF
