build xen kernels as part of i386 release
Hi,
Attached are some diffs to i386 code, to integrate Xen kernels. There are
3 parts here:
- add xen devices to the i386 MD devices. I think we want this anyway, to
avoid conflicts on the major numbers, and to share the MAKEDEV (we can
run a plain i386 kernel, or a xen0 kernel on the same root filesystem)
- add the xen kernels to the i386 release process. This way we don't have
a separate xen build and distribution, just extra kernels in the i386 one
- add support for xen devices to the install ramdisk, and provide a
XENU_INSTALL kernel with an embeeded ramdisk. This can be used either
as a standalone kernel to play with xen non-privileged domains, or to
to a NetBSD on a xen virtual device (instead of prepopulating the
filesystem from the domain0 system, which is not always easy).
Any comment/objections ? I'd like to commit this in a day or 2, and in any
case before 3.0 is branched.
