Tip: When creating disk, set bus=virtio and driver type virtio-blk or virtio-scsi. virtio-scsi is more flexible and recommended for production; load the scsi driver if you used scsi.
Complete Guide to Installing Windows 8.1 on a QCOW2 Disk Image
Load VirtIO drivers from the attached ISO for disk detection.
Whether you're a retro‑computing enthusiast, a QA engineer testing legacy software, or a sysadmin maintaining industrial machinery, following this guide ensures a successful deployment. Start with a clean ISO, master the driver‑load dance during installation, and maintain your QCOW2 images with periodic qemu-img checks.

When creating your QCOW2 image, use preallocation to improve performance:
If you prefer raw command-line isolation with hardware acceleration enabled via KVM, execute this syntax:
Before starting, ensure you have your Windows 8.1 ISO and the necessary virtualization drivers.
A Linux distribution (Ubuntu, Debian, Fedora, Arch, etc.) with KVM hardware virtualization enabled.
