Build a real Linux homelab that runs like a small private cloud, with QEMU KVM, libvirt, and virt manager working together instead of fighting you. Many homelab setups grow from a few test VMs into a fragile pile of hosts, images, and half documented tweaks. Networking is inconsistent, GPU passthrough is hit or miss, and nobody is really sure how to rebuild the environment if a disk fails. This book is written to move you past that phase and into a deliberate, reproducible virtualization platform. QEMU/KVM Virtualization: Build Your Linux Homelab and Cloud Infrastructure gives you a full, end to end workflow. You start from host validation and base installation, progress through VM creation and networking, then move into performance tuning, GPU passthrough, cloud style provisioning, automation, and day to day operations. Every concept is grounded in how libvirt, QEMU, and the Linux host actually behave, so you can make decisions with confidence. Understand how KVM, QEMU, libvirt, and virt manager fit together in a clean virtualization stack. Choose host hardware, CPU virtualization features, IOMMU settings, and firmware modes that support passthrough and future growth. Install and verify QEMU, KVM, libvirt, and virt manager, validate kernel modules, and solve common service and permission issues early. Model domains, networks, storage pools, and volumes correctly in libvirt, and work safely with domain XML instead of guessing. Create Linux and Windows guests using both virt manager and virt install, with sensible defaults, VirtIO drivers, and QEMU Guest Agent integration. Work confidently with qcow2 images, qemu img workflows, snapshots, blockcommit and blockpull, and practical backup strategies that can be restored. Design virtual networks with NAT, bridging, macvtap, VLAN aware topologies, and safe port forwarding patterns for inbound services. Manage multi host environments over SSH or TLS, including naming, tagging, and baseline policies that keep fleets understandable. Implement PCIe and GPU passthrough with VFIO, OVMF, IOMMU groups, and hostdev configuration, and deal with reset and ROM problems without guesswork. Use cloud images and cloud init NoCloud to inject keys, users, networking, and packages, then turn them into golden templates and fast clones with libguestfs. Tune CPU models, vCPU pinning, emulator threads, IOThreads, hugepages, NUMA alignment, and swap discipline for predictable performance. Attach advanced devices with VirtIO, USB redirection, and virtiofs shared folders, while staying aware of performance and permission trade offs. Harden hosts and guests with sVirt confinement, nwfilter based network isolation and anti spoofing, and sensible secure remote access practices. Automate with libvirt hooks, Ansible community.libvirt, and Terraform or OpenTofu providers, so rebuilds and lab changes become routine instead of risky. Operate your homelab like a small cloud with live migration, observability via libvirt exporter and Prometheus, blueprints for segmented networks and backups, and a troubleshooting playbook for networking, storage chains, and passthrough. This is a code heavy, hands on guide with concrete Shell commands, libvirt XML, Ansible YAML, cloud init configuration, and HCL examples that you can adapt directly into your own lab and infrastructure as code repositories. Grab your copy today and turn your QEMU KVM setup into a reliable, reproducible homelab platform.
