Use new QEMU -audiodev to setup audio devices 
Migrate to the new `-audiodev` . This also clearly labels the audio inputs and outputs in audio mixers on the host.

Introduction

Quickemu is a very simple script to "manage" Qemu virtual machines. Each virtual machine configuration is broadly the same requiring minimal setup. The main objective of the project is to enable quick testing of desktop Linux distributions where the virtual machines can be stored anywhere, such as external USB storage.

Quickemu is opinionated and will attempt to "do the right thing" rather than expose rich configuration options. Quickemu is a frontend to the fully accelerated qemu-virgil. See the video where I explain some of my motivations for creating this script.

Replace VirtualBox with Bash & QEMU

Installation

Clone this repository:

git clone https://github.com/wimpysworld/quickemu.git

Install the qemu-virgil snap. You can find details about how to install snapd and qemu-virgil on the Snap Store page for qemu-virgil

snap install qemu-virgil
snap connect qemu-virgil:kvm
snap connect qemu-virgil:removable-media

Usage

  • Download a .iso image of a Linux distribution
  • Create a VM configuration file; for example ubuntu.conf
iso="/media/$USER/Quickemu/ubuntu/focal-desktop-amd64.iso"
disk_img="/media/$USER/Quickemu/ubuntu/focal-desktop-amd64.qcow2
disk=128G
  • Use quickemu.sh to start the virtual machine:
./quickemu --vm ubuntu-focal-desktop.conf

Which will output something like this:

Starting /media/martin/Quickemu/ubuntu-focal-desktop.conf
 - QEMU:     /snap/bin/qemu-virgil v4.2.0
 - BIOS:     Legacy
 - Disk:     /media/martin/Quickemu/ubuntu/focal-desktop-amd64.qcow2 (64G)
 - ISO:      /media/martin/Quickemu/ubuntu/focal-desktop-amd64.iso
 - CPU:      4 Core(s)
 - RAM:      4G
 - UI:       sdl
 - GL:       on
 - VIRGL:    on
 - Display:  1664x936
 - smbd:     /home/martin will be exported to the guest via smb://10.0.2.4/qemu
 - ssh:      22221/tcp is connected. Login via 'ssh user@localhost -p 22221'

Here are the full usage instructions:

Usage
  quickemu --vm ubuntu.conf

You can also pass optional parameters
  --delete   : Delete the disk image.
  --efi      : Enable EFI BIOS (experimental).
  --restore  : Restore the snapshot.
  --snapshot : Create a disk snapshot.

TODO

  • Make display configuration more robust
  • Improve stdout presentation
  • Make disk image optionally size configurable
  • Improve snapshot management
  • Create desktop launcher for a VM
  • Get QEMU -audiodev working for audio input, something like:
