Are they going to be hvm guests from Linux > POV? Or something else? That's not set on stone, they could certainly be HVM guests depending on the implementation that each OS has. IMHO from a guest POV the interface exposed is very similar to PVH, so in order to ease the implementation I think they should be considered PVH guests from Linux POV, we can always move them to being HVM guests later if needed.
