To prepare a qemu disk as installation target run following commands and set disk=/dev/nbd0 in config.sh:

img="/var/lib/libvirt/images/ts-linux-testing.qcow2"
qemu-img create -f qcow2 -o size=20G $img  # create image
qemu-nbd -c /dev/nbd0 $img  # create device from image
qemu-nbd -d /dev/nbd0       # release device

Partition schema

  • partition=mbr-single, recommended for small VMs, will prepare
    • a mbr partition table
    • a single partition formated as ext4 partition
    • install grub-pc
  • partition=efi-single, recommended for small physical servers, will prepare
    • a gpt partion table
    • a 310 MB partition for efi
    • a 50 GB partition for the operation system
    • a partition with the remaining disk space for a luks container
