Install the qemu-guest-agent found inside the VirtIO ISO. This allows the host OS to handle clean shutdowns, reboots, and live backups seamlessly.

You can create a virtual machine (VM) and install Windows 8.1 on it using the following command. Before running the command, replace /path/to/win8.1.iso with the actual path to your Windows 8.1 ISO file. Follow a step-by-step walkthrough for setting up QEMU

For a similar footprint with security updates, use Windows 10 LTSC 2021 (but it’s heavier). For pure speed, try ReactOS (unstable) or a Windows 7 VM (also EOL).

The format provides —when you take a snapshot of a VM, only the changes are saved, dramatically reducing storage requirements. You can create live snapshots without powering down the VM, revert to previous states instantly, and even use backing files where multiple VMs share a common base image while maintaining their own unique changes. QCOW2 also supports compression, encryption, and sparse allocation (where the file only uses space for data actually written, not the full provisioned size).

At least 20 GB of physical disk space allocated to the QCOW2 image. Step 1: Create the QCOW2 Virtual Disk
