[OSSTest PATCH [RFC] 0/4] New test case: Fedora PV guests

Hi,

here they are more OSSTest bits, but this time implementing an actual test
case! ;-P

In fact, this series adds one test case (resulting in a few jobs) for a Fedora
PV guest, instead of the fairly typical Debian one. Basically, what we do is we
install a guest via the Anaconda installer with a kickstart file, allowing for
completely automated installation (much like d-i preseeds), and the run it
through the usual `test-guest'' procedure from sg-run-job: start, stop,
save/restore, local migration).

Jobs are introduced, in this series, for a Fedora19 guest and for a
Fedora20-RC1 one... PV guests, in both of the cases. I''m now adding a
few words
on why I think this could be useful.

Well, first of all, the more testing the better, of course. With this respect,
Fedora updates the kernel (and that would mean the guest kernel, as far as
these test jobs are concerned) fairly often, meaning we get the chance to test
how staging does with an almost current DomU kernel, independently from what
Dom0 kernel is being used. For instance, F19 had a 3.9 when released, while it
is on 3.11.10 as of now. That''s the reason why I think having a F19
test case
(right now, it''ll become F20 as soon as that will be released, later in
December) could be valuable.

The reason why I also included 20-RC1 jobs is the Fedora ''DomU
chriterion''. So,
long story short, the Fedora release chriteria includes this: ''The
release must
boot successfully as Xen DomU with releases providing a functional, supported
Xen Dom0 and widely used cloud providers utilizing Xen'' [1]. If a
Fedora TC
(stands for Test Compose) or RC does not boot as a PV guest, it can''t
be
released. Well, for the last couple of releases Konrad and I tried to cover for
the testing necessary to assess this, and we did manage quite well. Still, it
would be really great to have this integrated in OSSTest, as that would
guarantee much more coverage and reliability, for the benefit of both
Xen''s and
Fedora''s communities.

Add to the above the fact that, if we''re scarce on test hardware, there
is
really no need to run neither both nor even just one of the test cases/jobs
described above in all the flights.  It may well be enough to have the
"released" (so, the F19 one right now, the F20 one from F20 on, and so
on and
so forth), like, once a week, while the TC/RC (i.e., the equivalent of the
20-RC1 jobs in this series) could be scheduled to happen only when the time of
a new Fedora releas approaches, i.e., when the TCs and RCs are actually
available!  :-)

The new jobs introduced in this series are these:

 $ sqlite3 standalone.db ''select * from jobs;'' | grep fedora
  standalone|test-amd64-i386-fedora19-x86_64|test-fedora|queued
  standalone|test-amd64-i386-fedora20-RC1-x86_64|test-fedora|queued
  standalone|test-amd64-i386-fedora19-i386|test-fedora|queued
  standalone|test-amd64-i386-fedora20-RC1-i386|test-fedora|queued
  standalone|test-amd64-amd64-fedora19-x86_64|test-fedora|queued
  standalone|test-amd64-amd64-fedora20-RC1-x86_64|test-fedora|queued
  standalone|test-amd64-amd64-fedora19-i386|test-fedora|queued
  standalone|test-amd64-amd64-fedora20-RC1-i386|test-fedora|queued

(it''d be possible to include armhf jobs too, but I left this commented
out for
now, as I haven''t tested it).

Right now, changing the releases that we want to test, e.g., switching from
20-RC1 to 20-RC2 (when available), requires actually changing
''make-flight'',
which I don''t think is that sexy... This is the main reason why this
series is
an RFC... IanJ, IanC, are there better ways to achieve this?

I tested this in standalone mode, e.g., via:

 ./standalone-reset
 ./sg-run-job build-amd64
 ./sg-run-job build-amd64-pvops
 ./sg-run-job test-amd64-amd64-fedora19-i386

or:

 ./standalone-reset
 ./sg-run-job build-amd64
 ./sg-run-job build-amd64-pvops
 ./sg-run-job test-amd64-amd64-fedora20-RC1-x86_64

And it all seems to have worked. :-)

The series can be pulled from the following git branch:

Thanks and Regards,
Dario

Doesn''t this duplicate some of the code in ts-redhat-install ?

It seems to me that it would probaby be better to treat the
rpm/kickstart ecosystem as more of a single kind of thing.
So perhaps this new perl module should have a different name, too.

I''m not sure I like this kind of downloading of test OS code for each
platform.  This is sustainable for one distro (the Debian which most of
our tests use), but if we need to maintain a local mirror for every
test target OS the infrastructure is going to be a royal pain to
maintain.  And we''ll be exposed to a much wider range of failures
which will cause spurious test failures.  This surely applies to
release images - couldn''t they just be stored in the osstest images
directory ?

OTOH if we are having a Fedora-specific flight for checking RCs, I
think downloading things directly from the Fedora upstream is fine.

You shouldn''t use /tmp really like this.  Please use a

Perhaps there is other similar code that this could be combined with.

This messing with authorized_keys is very similar to code that appears

This is duplicating some of the logic in ts-redhat-install ?

The Debian guest installation is split into ts-debian-install and
ts-debian-fixup, so that editing the fixup code doesn''t involve
rerunning the time-consuming installation step.

Would that be worth doing here as well ?

This puts the Fedora arch name in the job name.  I think it would be
better if our job names used a consistent arch naming scheme (i.e.,
the Debian one).

According to your 0/4 message, this creates a large number of new test
jobs, but you''re patching the ordinary make-flight.  So I think this
isn''t really suitable as it is.

Probably what we want is one or two extra jobs in the existing flights
(for testing new Xens still work with released Fedora) and a new more
comprehensive kind of flight for testing Fedora RCs.

Perhaps.  I''m not sure whether it wants to be a different script or
not.  We already have some linux-specific flights which suppress most
of the jobs.  Maybe it would be better done with some ifs in the
existing script, or something.

If you do invent a make-fedora-flight you will have to factor out the
build parts of make-flight into a separate sub-script or a function in
a sourced file, or something.

> Well, given the fact that Debian is installed with xen-tools, there''s
probably more fixup to do there than here, and that''s why it looked
sensible enough to keep the two together in this case.

Anyway, I think being able to change what we do during fixup without
necessarily having to reinstall is something valuable to have. I''ll go
for it.

Dario

I''ll check. What I care
is for these jobs to keep being usable in standalone mode, if going that
way is not a problem wrt that, I think I can.

Also, this are not .iso or disk images, they''re just a kernel and a
ramdisk, but I guess that does not make much of a difference.

I''ll check what RH testcases do, as well as what Roger did for FreeBSD,
as I remember seeing something about downloading images and storing them
in the proper place in those patches too.

I was under the impression that this won''t be much useful, but I guess
it would, in case something goes wrong during installation and one wants
to debug... Is that the reason?

Yes.  However it''s done, from the pov of the database and the cron
jobs it would probably be a new $branch, but that doesn''t mean it
can''t have a new script.

I don''t have a fixed opinion about whether ifs in make-flight are the
right approach, compared to a separate script.  You should pick for
yourself the one that makes the code smaller and/or less complicated
:-).

Ian.

I mean $c{Images}.  You could provide a script (mg-download-fedora) to
download/update them.

Indeed.  The debian-installer stuff goes in /tftpboot but is handled
much the way I''m suggesting.

No, it''s because in the future I want to be able to run multiple test
jobs on a single host, so the pathnames oughtn''t to be fixed.  And
there is no good reason for using /tmp here.  /tmp has a number of
problems (many of which don''t apply here, admittedly) so it''s
not a
good habit to use it.

We''re talking about paths on the test host dom0 here, right ?
