I just installed Windows XP twice, once without the patch and once
with the patch. The command line I used for this was:

qemu-system-x86_64 -m 3G -cpu host -enable-kvm -M pc-1.0 -drive file=disk.qcow
2 -cdrom en_windows_xp_professional_with_service_pack_3_x86_cd_vl_x14-73974.iso

Aside from the nostalgia being completely overwhelming, both installs
were successful, and I was greeted with the terrific bliss.bmp
