An MCP server is not a new API. It is a thin layer over the one you already have
Somewhere in the last year, "do we need an MCP server?" joined the list of questions that arrive in a brief before anyone has said what the thing is for. It is usually framed as MCP vs API, as though the Model Context Protocol were a newer kind of AP...

Notes on x86 PVH boot
Motivation My Rust KVM project now being able to boot Linux on ARM64, I decided to try and boot Linux on x86. I have been trying in the past to set up the boot procedure via bootparams struct. At the time it was a lot more complex and now I wanted ...

Booting ARM64 Linux in my Rust KVM Hypervisor: Getting to the console with help of eBPF
Recap In the previous article../kvm-rust-arm-linux-part1 I got ARM64 Linux as far as executing inside my Rust KVM hypervisor. I still couldn't actually interact with the guest, though: I had no working console. This article is about getting from "...

What is GPU Passthrough?
GPU passthrough is a virtualisation method used to directly assign a physical graphics processing unit to a single VM, ultimately bypassing the virtualisation software layers like the NVIDIA Virtual GPU vGPU1 manager. In this configuration, the physi...

Booting ARM64 Linux in my Rust KVM Hypervisor: Debugging a Memory Issue
Motivation The time has come: the big test. I got some simple binaries running on my Rust KVM hypervisor at this point I am thinking about giving it a proper name. The next thing has to be Linux. For this series I will show how to actually boot Lin...

KVM vs KVM - what is the question?
Last weekend I was looking for a new project for my Raspberry Pi. I was looking for ways to set up a KVM on my Pi5 since it has 8GB of RAM, which is beefy enough for additional virtualisation tasks. Once I started Googling how I should start this tas...

Developer Weekly Briefing — October 30, 2026
Security dominated this week, but not in the usual way. Two active campaigns turned GitHub configuration files into attack surfaces. Researchers demonstrated that the built-in browsers inside AI coding tools can read your SSH keys. And at Oracle AI ...

Porting my Rust KVM hypervisor to ARM64: Running the binary
Recap In the previous article../kvm-rust-arm-part1 we ported the register handling of my Rust KVM hypervisor from x86 to ARM64. By tracing QEMU with strace and inspecting the Linux headers, we discovered that ARM64 accesses CPU state through the KV...

Porting my Rust KVM hypervisor to ARM64: Working with registers
Introduction This is a follow-up to my KVM in Rust series where I showed how to use strace and GDB to reverse-engineer QEMU/KVM and reimplement pieces of it in my own hypervisor in Rust. So far this was done on a modern x86 CPU. This time we'll see...

Building a KVM Virtual Machine in Rust: Running a binary
Recap This is a continuation of Part 2../kvm-rust-part2 of KVM in Rust series, where we successfully set up a memory region for our guest VM. Now we will see how to proceed further and run a very simple binary in our hypervisor. Loading the binary...

Building a KVM Virtual Machine in Rust: Memory Setup
Recap This is a continuation of my previous article../kvm-rust-part1 which dealt with reverse-engineering QEMU with strace to learn how KVM works. Now it's time to try and follow the steps we got from the strace logs to build our own KVM-based virt...

Learning KVM by Reverse-Engineering QEMU with strace
Motivation I work with virtual machines in QEMU/KVM environment a lot. In order to debug, optimize and customize the VMs requires an in-depth knowledge of both QEMU and KVM, the Linux kernel virtualization subsystem that exposes hardware virtualiza...
