expanding distro Xen version choices for Stretch, Buster, Bionic, Disco, & Eoan

Hello,

When ub1910/Eoan is released next month you will have xen-4.9 in repo.

Currently, Buster has xen-4.11.x and Stretch is at xen-4.8.x.

If you want source builds and binary packages for all available
versions (except unstable), join in at
##xen-packaging on Freenode IRC

Most of the builds also have a companion cross_compile source build for arm64.
All of the source builds have strict debian deltas and the binary
builds are done in a proper chroot running pbuilder/debhelper.

For Disco,

the Centos Virt-Sig has planned to build xen-4.12.1 for CentOS 8.

I took a look and noticed that this build must support python2 &
python3, not python, and we can not expect any qemu-system-x86 built
with Xen libs. The only qemu builds seen are kvm only.

I've got a package set done:

the qemuu & qemut are upstream and traditional, packaged separately.

I've yet to do a bare-metal install and test these. If anyone wants to
help with testing, see me
##xen-packaging on Freenode IRC or send mail.

There are some missing entries in the el8 kernel config that break
dom0 suuport, although domU works fine. The kernel-ml team has planned
to fix dom0 support for the next el8 release, expected around October
14,15.

I compared the kernel-ml-5.3.2 with the working kernel-5.0.0 in ub1904:

Difference between kernel-5.0.0 in ub1904 and kernel-ml-5.2.3 in elrepo:

I now have a good bare-metal install of C8 and a good set of Xen
packages, but my dom0 install failed to work because of missing
drivers in kernel-ml.
