Troubleshooting
If you run into problems installing W2K or XP Os, run qemu without acpi and kqemu.
$ qemu -cdrom /dev/acd0 -hda kwinxp.img -m 512 -boot d -no-kqemu -no-acpi -localtime
If you are running a server without X, access your VM through VNC
$ qemu -cdrom /dev/acd0 -hda kwinxp.img -m 512 -boot d -kernel-kqemu -vnc :0 -localtime
