QEMU

Q: How deeply does Rust in Action: Systems programming concepts and techniques cover QEMU?

Defines virtualization and demonstrates installation verification, but does not explain QEMU command-line operation.

As explained in Rust in Action: Systems programming concepts and techniques

QEMU is an open-source machine emulator and virtualizer that runs operating systems and programs for multiple computer architectures.

QEMU is virtualization technology used to run an operating system for a supported computer architecture. In kernel development, it provides a fast environment for launching and rerunning a small experimental OS. section 11.1.1 section 11.7

Use QEMU as one part of a kernel-development toolchain:

Install QEMU alongside Rust, bootimage, cargo-binutils, and LLVM tools. section 11.1.1
Ensure qemu-system-x86_64 is available on the system PATH. section 11.1.2
Use the virtualized machine to run a bootable kernel and repeat experiments when the OS crashes. section 11.1.1 section 11.7

Verify QEMU

Run qemu-system-x86_64 --version. A successful installation reports the QEMU emulator version, such as 4.2.1. section 11.1.2

$ qemu-system-x86_64 --version 
QEMU emulator version 4.2.1 (Debian 1:4.2-3ubuntu6.14)
Copyright (c) 2003-2019 Fabrice Bellard and the QEMU Project developers

Inspect a concrete QEMU version check and its successful command-line output. section 11.1.2
