How to run Firecracker without KVM on cloud VMs
(alexellis.io)
In this post I want to introduce a novel way to run virtual machines, namely microVMs on cloud VMs where KVM is not available.

Isolating Containers with ZFS and Linux Namespaces
(klarasystems.com)
Containers provide an efficient way to isolate workloads, but managing storage and resource separation can be challenging. This article explores how ZFS and Linux namespaces work together to optimize containerized environments, ensuring storage flexibility, workload isolation, and enhanced control. Learn how to leverage ZFS datasets and Linux namespaces for multi-tenant architectures while maintaining performance and security.

Linux as co-operative Windows process (2017)
(colinux.org)
Cooperative Linux is the first working free and open source method for optimally running Linux on Microsoft Windows natively. More generally, Cooperative Linux (short-named coLinux) is a port of the Linux kernel that allows it to run cooperatively alongside another operating system on a single machine.

Updated FreeBSD Bhyve Companion Tools

Some time ago I wrote about how FreeBSD Bhyve can be used in the FreeBSD Bhyve Virtualization article. It was quite short after I moved from VirtualBox – and to be honest – I am really glad that I moved to Bhyve.

Cloud Virtualization: Red Hat, AWS Firecracker, and Ubicloud internals
(ubicloud.com)
VMs are much harder to understand today than they were back in 2009. Linux provides many building blocks for virtualization, but only a select few kernel engineers know how to stitch them together.

Parallels can run x86 versions of Windows or Linux on Apple Silicon
(arstechnica.com)
Virtualization software like Parallels and VMware Fusion give Mac owners the ability to run Windows and Linux on top of macOS, but for Apple Silicon Macs, that support was limited to the Arm-based versions of those operating systems.

How Proxmox VE shreds your SSDs – with details

Time has come to revisit the initial piece on inexplicable writes that even empty Proxmox VE cluster makes, especially we have already covered what we are looking at: a completely virtual filesystem 1 with a structure that is completely generated on-the-fly, some of which never really exists in any persistent state - that is what lies behind the mountpoint of /etc/pve and what the process of pmxcfs created the illusion of.

Make your QEMU faster (2022)

NixOS uses virtual machines based on QEMU extensively for running its test suite. In order to avoid generating a disk image for every test, the test driver usually boots using a Plan 9 File Protocol (9p) share (server implemented by QEMU) for the Nix store, which contains all the programs and config necessary for the test.

Creating a Proxmox or QEMU ChromeOS Flex VM

I recently wanted to experiment with ChromeOS Flex but didn’t want to install it on a physical machine. I also was doing this without a USB key, which complicated things slightly.
