Not so much, after using qemu-img to create a vdisk, something like:
   qemu-kvm -m 500 -hda MyXP.img -cdrom XPimageCD.iso

Depending on your install your may want "-vga std" but the initial boot will 
notice no bootable image on the vdisk, you probably will be fine without 
specifying sound hardware, etc. And installing on console rather than vnc saves 
hassles there. Older qemu may want -std-vga and stuff like that, but it really 
doesn't take much. If the vdisk has not bootable partitions the -boot is optional.
