How to mount a qcow2 disk image

This is a quick guide to mounting a qcow2 disk images on your host server. This is useful to reset passwords, edit files, or recover something without the virtual machine running.

Step 1 - Enable NBD on the Host

modprobe nbd max_part=8

Updating a feature branch

First we'll update your local master branch. Go to your local project and check out the branch you want to merge into (your local master branch)

$ git checkout master

Fetch the remote, bringing the branches and their commits from the remote repository. You can use the -p, --prune option to delete any remote-tracking references that no longer exist in the remote. Commits to master will be stored in a local branch, remotes/origin/master

We install certutil and pk12util if necessary:

sudo apt install libnss3-tools

On Linux, Chromium uses the NSS Shared DB. Check if you have the ~/.pki/nssdb directory:

ls $HOME/.pki/nssdb

	# Allow read-only ZoL commands to be called through sudo without a password.
