Execute QEMU to boot the Windows XP ISO, mounting the QCOW2 disk and the VirtIO floppy drive:

While functional, running Windows XP on modern virtualization presents unique challenges. One common problem when migrating a working Windows XP virtual disk from a raw to a QCOW2 format is the message on boot. This is often due to configuration mismatches in the boot device, and careful verification of the virtio bus assignments is required.

Using VirtIO bypasses heavy hardware emulation, allowing your QCOW2 disk to read and write at near-native SSD speeds. Managing and Compressing Your QCOW2 Image windows xpqcow2

Virtual QCOW2 images should never be defragmented, as it artificially expands the file size on your host machine.

To reclaim space on your host machine, run a defragmentation tool inside Windows XP, use a tool like sftzero to write zeroes to empty space, and then shut down the VM. Execute QEMU to boot the Windows XP ISO,

Now launch my_experiment.qcow2 . All writes go to the new file. The base stays untouched. Want five different XP flavors (Gaming, POS, Hacking lab, Retro dev, Malware analysis)? Each one is just a few MB — thanks to copy-on-write.

Ready-to-use QCOW2 images can sometimes be found on platforms like SourceForge or community forums, though creating your own is safer for security. Convert from VDI/VMDK: Now launch my_experiment

If you already have a Windows XP virtual machine in VirtualBox (VDI) or VMware (VMDK), you can convert it using qemu-img convert -f vdi -O qcow2 winxp.vdi winxp.qcow2 Create New:
