Windows XP remains a vital operating system for running legacy industrial software, retro games, and malware analysis labs. When virtualizing this OS on modern hypervisors like QEMU or KVM, the QEMU Copy-on-Write ( .qcow2 ) disk image format is the absolute gold standard.

Select the host passthrough type or a generic kvm64 processor. Allocate 1 to 2 cores. Windows XP does not handle high-core topologies well.
By using the approach, you can keep your legacy applications running reliably in a containerized environment, preserving the past while utilizing the full power of modern 2026 hardware. When virtualizing this OS on modern hypervisors like
If you need a compact, portable VM image of Windows XP for legacy testing, retro software, or preservation, using a qcow2 disk image combines small on-disk size with useful features (snapshotting, sparse allocation, compression, and optional encryption). Below is a concise, practical reference you can use or embed in documentation.
Shut down the VM, and run the following command on your host terminal to create a freshly compressed, shrunken version of your QCOW2 file:
