Running Windows XP in a Qcow2 Virtual Machine: A Comprehensive Guide
Running legacy operating systems like Windows XP on modern hardware is a common requirement for developers, enthusiasts, and system administrators who need to access old software, games, or legacy database systems. Utilizing (QEMU Copy On Write) disk images with QEMU or KVM is the most efficient, flexible method, offering snapshot capabilities and thin provisioning.
The conversion process begins by installing Windows onto a RAW disk image. This method provides a clean, uncompressed disk layout that you'll later convert to Qcow2.

Download the latest virtio-win ISO from the Fedora project: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/ . For Windows XP, versions around 0.1.96 to 0.1.185 offer the best compatibility. Later releases may have removed floppy support or introduced bugs on XP.
One of the main advantages of the Qcow2 format is its management capabilities.
Save 90% of disk space by creating a base XP image and cloning it:
qemu-img create -f qcow2 -o compression_type=zstd xp.qcow2 20G For testing/legacy software only
Use the qemu-img command-line utility to allocate a fresh, dynamically expanding QCOW2 virtual drive. For Windows XP, a 20 GB to 40 GB limit is more than sufficient for applications and virtual memory paging. qemu-img create -f qcow2 windows_xp_base.qcow2 40G Use code with caution. Step 3: Launch the Installation Environment
Provides smooth resolution scaling and matches legacy driver sets. if=ide (Standard) or VirtIO
Windows XP (SP3) – Qcow2 Image for QEMU/KVM
Running using the QCOW2 (QEMU Copy-On-Write) disk format is a popular way to preserve legacy software or games in a virtual environment like QEMU or KVM. QCOW2 is favored because it only uses physical storage for the space actually written to by the VM, making your "20GB" virtual disk take up very little space on your host machine initially. 1. Creating the QCOW2 Disk Image Utilizing (QEMU Copy On Write) disk images with
Essential for modern performance. Since XP predates modern virtualization standards, you need the "VirtIO-win" floppy image to recognize virtual hard drives during setup. Creating the Windows XP QCOW2 Image
Leverage the advanced features of Qcow2 to get the most out of your VM.
Yes, through the magic of QEMU emulation. You can run an x86 version of Windows XP on an ARM host using QEMU's system emulation ( qemu-system-x86_64 ), which will emulate an x86 CPU. Performance will be significantly lower than on an x86 host due to the emulation layer, but it is possible.
This command creates a 10 GB Qcow2 image named winxp.qcow2 . Windows XP itself occupies roughly 2–3 GB after a clean installation, but allocating 10–20 GB provides room for applications and future growth. If you are testing or working within tight storage constraints, 5 GB is sufficient for basic needs . The -f qcow2 flag specifies the format.
Default IDE and Realtek 8139 drivers function adequately for local storage. However, when accessing disk files over a network or demanding high I/O, performance degrades significantly. VirtIO drivers provide paravirtualized I/O, dramatically improving disk and network throughput.
