If you ever need a way of modifying content of qcow2 disk images, here is how to do it:
sudo apt-get install qemu-utils
sudo modprobe nbd max_part=8
sudo qemu-nbd --connect=/dev/nbd0 /path/to/qcow2/image
The first command loads the nbd kernel module. The "max_part=N" option specifies the maximum number of partitions we want to manage with nbd.
Check the partitions:
sudo fdisk /dev/nbd0 -l
Finally, choose any one partition (e.g., /dev/nbd0p1) and mount it to a local mount point (e.g., /mnt).
sudo mount /dev/nbd0p1 /mnt
