Log Message:
Initial import of a xen3 kernel package, to facilitate xen3 dom0 support
in NetBSD.

	Xen is a virtual machine monitor for x86 hardware (runs only on
	i686-class CPUs), which supports running multiple guests operating
	systems on a single machine.  Guest OSes (also called "domains")
	require a modified kernel which supports Xen hypercalls in replacement
	to access to the physical hardware.  At boot, the xen kernel is loaded
	(via grub) along with the guest kernel for the first domain (called
	domain0).  domain0 has privileges to access the physical hardware (PCI
	and ISA devices), administrate other domains and provide virtual
	devices (disks and network) to other domains.

	This package contains the Xen3 kernel itself.
