The use of Windows XP (QEMU Copy-On-Write) format represents a unique intersection between legacy computing and modern virtualization. While Windows XP reached its end-of-life in 2014, it remains a necessity for running proprietary industrial software, legacy databases, and retro gaming. Utilizing the QCOW2 disk image format—the native format for

sudo apt update
sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients virt-manager qemu-utils

List snapshots

qemu-img snapshot -l winxp.qcow2

5) Installing Windows XP (example with qemu)

• If using virtio for disk/network, download VirtIO driver ISO (e.g., from Fedora/Red Hat) and attach during install.
• Example qemu command (IDE disk, simple NAT networking):

9. Integration with Proxmox (Example)

1. Upload winxp.qcow2 to Proxmox storage (e.g., local-lvm).
2. Create VM:
   • CPU: 1–2 vCPUs
   • Memory: 1024–2048 MB
   • Disk: qcow2 20 GB
   • Video: cirrus or std/vga; use QXL + SPICE for better graphics if guest additions available
   • Network: e1000 (no drivers required) or virtio (better perf, needs drivers)
