==== Mount a .qcow image ====
Found the answer [[https://gist.github.com/shamil/62935d9b456a6f9877b5|here]], even if it doesn't indicate that it needs to be run as root.

  sudo modprobe nbd max_part=8
  sudo apt-get install qemu-utils
  sudo qemu-nbd --connect=/dev/nbd0 /path/myimage.img
  sudo fdisk /dev/nbd0 -l
  mkdir ~/mnt
  sudo mount /dev/nbd0p2 /home/user/mnt

  sudo umount /home/user/mnt
  sudo qemu-nbd --disconnect /dev/nbd0
  sudo rmmod nbd
