QCOW2 (QEMU Copy-On-Write) is a flexible disk format that offers several advantages over traditional "fixed" or "raw" images:

You may need the virtio-win drivers if you chose VirtIO for disk or network performance, though standard IDE/E1000 emulation is often more "plug-and-play" for XP. 4. Common Performance Fixes
For optimal performance on Linux hosts, enable KVM hardware acceleration:
: Playing early 2000s PC games that rely on DirectX 9.0c or specific vintage drivers. Why Choose QCOW2 Over Other Virtual Disk Formats? Whether the VM requires like physical PCIe or
: Unlike raw images, QCOW2 files only occupy actual space on your physical drive as data is written inside the VM.
Last week, I needed to run an old Delphi 7 project (only works on XP). Instead of digging out a dusty ThinkPad, I:

Modern VirtIO network adapters will not work out of the box. Stick to emulated hardware via -net nic,model=rtl8139 or -net nic,model=e1000 .
If you can tell me you are using (e.g., Proxmox, QEMU on Linux, or VirtualBox), I can provide the exact commands and setup steps for your system. Share public link
