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

Debloating Nox

Nox, despite being the most feature-filled Android emulator, has a lot of negativity surrounding it due to their antics when it comes to making income off of their program. It is known for running repeated advertisments in the background, calling home and passing along system information (outside of your Android instance) as well as a vast amount of potentially sensitive data in an encrypted payload back to their multitude of servers. With the following preventitive measures, we can stop a majority of this happening as well as greatly improve the overall performance.

Download and Install a fresh copy of Nox. The latest version is fine (for now). If you already have it installed, that is fine too. No need to reinstall.
Enable Root Mode on Nox by clicking the gear icon and then checking the Root Startup box.
Install a new Launcher from the Play Store. ANYTHING but Nox's default. I suggest [Nova Launcher](https://play.google.com/s

Autocomplete server names for SSH and SCP for Git Bash

For ssh

1. Make a file with name `ssh` as following content:

_ssh() 
{
    local cur prev opts
    COMPREPLY=()
    cur="${COMP_WORDS[COMP_CWORD]}"
    prev="${COMP_WORDS[COMP_CWORD-1]}"

The Windows version of OpenSSH client doesn't include a ssh-copy-id command. I don't know why. If it does one day, then this can be ignored.

NOTE If you have Windows Subsystem for Linux (WSL) installed, you can use the linux version of ssh-copy-id instead. Go to the description at the end of this document.

Download the file ssh-copy-id.cmd to your Windows PC, or copy and paste its contents.
Run the script passing your linux ssh information (for example ssh-copy-id.cmd [email protected]). This should work with any Linux platform. Alternatively, if you have experience, you can use the powershell version. ssh-copy-id.ps1. Run the script as powershell .\ssh-copy-id.ps1 [email protected].
Run the command for each linux account you connect with. You will be prompted for your Linux host password. If you have more than 1 account on any machine, you must do this for each account.

The file name and location of the script is not important but the filename extension must be .cmd

Edit 22/8/2021: I have updated MEmu and it seems like it reinstalls the apps and re-enables the services. Repeat steps 5, 7, 8, and 9 if you update MEmu.

Debloating MEmu

In my experience, Nox can be quite slow and choppy, and looks like I'm not the only person with this problem. A lot of people say that MEmu performs better than Nox, and I could agree with that. I have no chopping issues with it so far. But like Nox, there are kinda shady stuff going on.

	Begin by enclosing all thoughts within <thinking> tags, exploring multiple angles and approaches.
	Break down the solution into clear steps within <step> tags. Start with a 20-step budget, requesting more for complex problems if needed.
	Use <count> tags after each step to show the remaining budget. Stop when reaching 0.
	Continuously adjust your reasoning based on intermediate results and reflections, adapting your strategy as you progress.
	Regularly evaluate progress using <reflection> tags. Be critical and honest about your reasoning process.
	Assign a quality score between 0.0 and 1.0 using <reward> tags after each reflection. Use this to guide your approach:

	0.8+: Continue current approach
	0.5-0.7: Consider minor adjustments
	Below 0.5: Seriously consider backtracking and trying a different approach
