You can create a "master" Windows XP image and spawn multiple linked clones. Each clone uses minimal disk space, writing only its unique changes to a separate delta file. Step-by-Step: Creating a Windows XP .qcow2 Image
Windows XP does not natively support modern multi-core virtualization topologies or VirtIO drivers out of the box. The initialization script must present a hardware environment tailored to late-1990s and early-2000s architecture while leveraging modern kernel-level acceleration. Save and execute the following deployment script:
Windows XP only requires 2 GB to 10 GB of space. A .qcow2 file only occupies the actual space used by the guest OS, saving hosting drive capacity. windows xpqcow2
