Introduction

I was playing around with kubevirt.io (v1.2.0) on a Radxa ROCK 5 Model B. When I tried to boot a VM, I just had the qemu-kvm process eating 100% CPU with no output to the console.

I built an alternative setup based on ubuntu 22.04 and qemu worked with KVM without any problems. After some investigation I had the idea that it might be related to the (U)EFI bios used. I transferred the /usr/share/AAVMF/AAVMF_CODE.fd files from the 22.04 setup into the kubevirt compute container, started an additional qemu-kvm with -bios AAVMF/AAVMF_CODE.fd and voila - KVM booted correctly.

Findings

My findings so far:

Create system drive

qemu-img create -f qcow2 alpine.qcow2 16G

Install image

Linux

Backblaze B2 via rclone cheatsheet

Create B2 remote

Reference

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.
