What, precisely, are you expecting to witness while running the Windows
XP install ISO? To my knowledge, it does not support anything but GUI
installation, and it looks like you have turned off graphics output
using the -nographic flag.

The qemu executable you use is the one you want the guest to emulate,
not the one that matches your host. qemu-system-x86_64 will emulate a
64-bit Intel/AMD system; qemu-system-i386 will emulate a 32-bit
Intel/AMD system; qemu-system-mips will emulate a MIPS-architecture
system. All will run on the host upon which they were built.
