QEMU-KVM in Arch Linux

Check Virtualization Support

lscpu | grep -i Virtualization

VT-x for Intel
AMD-Vi for AMD

Ensure that your kernel includes KVM modules

Enable PipeWire on Ubuntu 22.04

This guide is only for original Ubuntu out-of-the-box packages. If you have added a custom PPA like pipewire-debian, you might get into conflicts.

Ubuntu 22.04 has PipeWire partially installed and enabled as it's used by browsers (WebRTC) for recoding the screeen under Wayland. We can enable remaining parts and use PipeWire for audio and Bluetooth instead of PulseAudio.

Starting from WirePlumber version 0.4.8 automatic Bluetooth profile switching (e.g. switching from A2DP to HSP/HFP when an application needs microphone access) is supported. Jammy (22.04) repos provide exactly version 0.4.8. So, we're good.

Based on Debian Wiki, but simplified for Ubuntu 22.04.

Discord Timestamps

Discord timestamps can be useful for specifying a date/time across multiple users time zones. They work with the Unix Timestamp format and can be posted by regular users as well as bots and applications.

The Epoch Unix Time Stamp Converter is a good way to quickly generate a timestamp. For the examples below I will be using the Time Stamp of 1543392060, which represents November 28th, 2018 at 09:01:00 hours for my local time zone (GMT+0100 Central European Standard Time).

Formatting

Style	Input	Output (12-hour clock)	Output (24-hour clock)
Default	`<t:1543392060>`	November 28, 2018 9:01 AM	28 November 2018 09:01
