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...

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...

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...

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...
