We basically implement the real hardware ipl procedure. This allows for booting Linux guests on vfio-ccw devices. vfio-ccw's channel program prefetch algorithm complicates ipl because most ipl channel programs dynamically modify themselves. Details on the ipl process and how we worked around this issue can be found in docs/devel/s390-dasd-ipl.txt.
