This guide is based heavily on the official guide from Variscite, with some additional info i found useful while learning this.

1.1 Ubuntu 16.04 LTS & 18.04 LTS

This tutorial was made with a machine running Ubuntu 18.04 LTS 64-bit, which worked almost flawless, though Variscite’s original tutorial is based on Ubuntu 16.04 64-bit.

1.2 Ubuntu 20.04 LTS

Compiling Yocto thud does not work on Ubuntu 20.04 LTS 64-bit. The GNU C library, or short glibc, is version 2.30 in Ubuntu 20.04, which is incompatible to glibc 2.29, which the bitbake command expects. This patch from OCtober 2019 in the OpenEmbedded Core Layer fixes this, but it hasn’t been implemented into the Variscite BSP for Yocto thud. The last update for the thud-fslc-4.14.78-mx7-v1.0 tag was in May 2019, so it probably won’t be updated anymore. Downgrading the glibc is not recommended, so you should compile it in a virtual machine or with docker.

How to run Windows 11 in GNOME Boxes (with UEFI and TPM2 emulation)

Thu, 19 Dec 2024 21:13:45 +0200

Windows 11 significantly raised its hardware requirements compared to Windows 10. Among the changes, it requires more RAM and storage space. It also requires a Trusted Platform Module (TPM) version 2.0 and a UEFI boot environment.

GNOME Boxes doesn’t yet support TPM and UEFI environments. However, the underlying virtualization technology supports it. You just need to tweak a few configuration options along the way. Read the instructions carefully!
