[Mark Pryor <tlviewer@xxxxxxxxx>]

Responding to this post:

I started with below sources from the Stretch repo:

http://http.debian.net/debian/pool/main/x/xen/xen_4.8.1-1+deb9u1.dsc
http://http.debian.net/debian/pool/main/x/xen/xen_4.8.1.orig.tar.gz
http://http.debian.net/debian/pool/main/x/xen/xen_4.8.1-1+deb9u1.debian.tar.xz

The rules.real was patched like this:

Three build-depends were added:

checkpolicy, m4, libfile-fcntllock-perl, dh-python

No changes to Config.mk were needed.

My backport sources are here:

http://prymar56.org//xen/debian/jessie-bp/48x/source/

The debian build of Xen uses a truncated source, with all qemu* & seabios sources removed.

There is no support for oxenstored (ocaml) nor

is there any OVMF support.

The systemd init system in upstream is also not included.
