Booting a Xen PVH guest requires a special boot entry as it is mandatory to setup some Xen-specific interfaces rather early. When grub or OVMF are used as boot loaders, however, those will fill the boot parameters in zeropage and there is no longer a need to do something PVH specific in the early boot path. This patch series adds support for that scenario by identifying PVH environment and doing
