[Xen-devel] [PATCH 0/3] automation: build Xen in openSUSE Tumbleweed

[Dario Faggioli <dfaggioli@xxxxxxxx>]

The openSUSE distribution comes in two flavours: Leap, which is
non-rolling, and released annualy, and Tumbleweed, which is rolling.

In general, they are quite similar, but the versions of the software
they ship can be significantly different. As it is easy to imagine,
Tumbleweed, being rolling, has much more recent and updated packages.

Actually, Tumbleweed often ships the most updated releases of various
software and projects, among many distribution around.

For instance, right now, Tumbleweed has gcc 9.1.1. Fedora Rawhide also
seems to have 9.1.1, while Fedora 30 has 9.0.1. Debian Unstable and
Ubuntu Disco both have 8.3.0, AFAICT.

Of course, it's not at all like "the more updated the better", or
anything like that! It's just that I see some value in having, as a part
of our CI:
- more diversity, in terms of versions of the packages/software we try
  to build Xen with and against;
- a "bleeding edge" environment, in order to catch, or at least be
  aware of, build issues with latest compilers and/or when linking
  against the latest version of this and that library.

Interestingly, in the past couple of days, a few build issues of Xen,
qemu-xen and ipxe (at the commit that we were checking out) with gcc
9.1.1 where discovered and fixed. And --at least as far as the ones
I've reported/fixed-- I found about them while building Xen in
openSUSE Tumbleweed (while working on this patch series :-D ).

Happy to hear what people think about all this. :-)

Oh, BTW, apart from adding the Tumbleweed dockerfile and CI jobs, the
series also does some minor tweaking of the already present openSUSE
Leap dockerfile (in patch 1).

Thanks and Regards.
