KVM

A deep dive into building a fully automated local Kubernetes cluster with Terraform and QEMU/KVM. One command provisions 3 VMs, installs Kubernetes via kubeadm, deploys Calico CNI, and joins workers automatically (no manual SSH required). Includes a detailed breakdown of the Terraform libvirt provider 0.8→0.9 rewrite and what breaking schema changes mean for your infrastructure code. Updated for v2.1 with the five bugs that kept Fedora 44 from booting.

Virt-Manager’s UI for duplicating virtual disks can be confusing. This bite-sized guide shows you exactly how to use Storage Pools and Backing Stores to create space-saving linked clones without ever touching the terminal.

Run the official Amazon Linux 2023 QCOW2 image locally on QEMU/KVM with Virt-Manager. Covers Cloud-Init seed ISO creation, SSH key setup, and an 8-test deep dive into the password locking behavior that most guides get wrong. The Cloud-Init concepts apply to VirtualBox, VMware, and Hyper-V too.
