Contrary to old myths, QCOW2 on a modern NVMe or SSD with cache=none or writeback is snappy. XP doesn’t know TRIM, but QEMU’s discard=unmap option passes through fstrim-like hints. Boot time from QCOW2 on a Ryzen 5600X: ~12 seconds from BIOS POST to desktop. That’s faster than XP ever was on spinning rust in 2002.
