SPICE or VirtIO mouse drivers don't exist for XP.

If you successfully downloaded a pre-made windows-xp.qcow2 file from a trusted source (like a colleague or archived lab), here is how to boot it instantly.

The primary driver for seeking a downloadable Windows XP qcow2 image is . A standard installation of Windows XP from an ISO file can take 30-45 minutes, followed by hours of downloading and installing hundreds of post-service-pack updates (which are no longer officially hosted by Microsoft). Pre-made images often come "pre-activated" and with common drivers or software patches. For a developer needing to test a legacy application in an isolated environment, a ready-to-run image is a quick solution. Additionally, hobbyists who wish to revisit classic games or UI designs from the early 2000s find these images an easy gateway to nostalgia.

You may need the VirtIO drivers for Windows if your hypervisor uses VirtIO for disk or network interfaces.
