linux-4.19 branch in xenbits is outdated, it haven't been updated and
tested since 2020 as it has been disabled in osstest. Also, this 4.19
branch doesn't build on Bookworm.

So we will start to use a newer version of Linux. We switch to 6.1 for
the Arm* tests recently, so will use that same version for x86.

Also, following commit 3a3089c94913 ("mfi-common: Drop Linux dom0 i386
tests for newer Linux branches"), 32bit dom0 isn't tested on newer
Linux, so we need to drop all dom0 i386 tests wherever the default
linux branch is used. That is, this changes in jobs will apply to
"xen-unstable" branch but also all xen stable branches, seabios, qemu,
osstest, libvirt, so every branch that aren't "linux-*".

Here is the list jobs that changes, and whether they are replace, or
have existing equivalents, on the "xen-unstable" branch. Changes
compared with:
    OSSTEST_CONFIG=standalone-config-example nice eatmydata ./standalone-generate-dump-flight-runvars

Gone, but replaced by a new test-amd64-amd64-*:
- test-amd64-i386-libvirt-raw
- test-amd64-i386-xl-vhd

Some test-amd64-amd64-* are also changed:
- test-amd64-amd64-libvirt-vhd
- test-amd64-amd64-qemuu-freebsd11-amd64
- test-amd64-amd64-qemuu-freebsd12-amd64

+ test-amd64-amd64-libvirt-qcow2
+ test-amd64-amd64-libvirt-raw
+ test-amd64-amd64-xl-vhd

In any case, the list of test would be the same as for the existing
branch "linux-linus" or "linux-6.1" branches.

There hasn't been comment on this change, so I guess everyone is happy
for this change to go in. :-)

I'll push it later this week.

I should have removed those long time ago, as FreeBSD has been EOL for
ages.

Is this purely a name change, or there's some kind of functional
change?

I'm mostly worried whether this could lead to regressions getting in
as osstest would detect those jobs as new instead of inheriting from
the previous jobs.  Also the "History for test ..." won't link to jobs
prior to the rename?

I guess I'm confused about what causes the qemuu to be dropped from
the job names above.

Thanks, Roger.

For test-amd64-amd64-qemuu-freebsd1{1,2}-amd64, it looks like the
"-qemuu" is a bug. The freebsd jobs shouldn't have used $qemuu_suffix,
as it doesn't use $qemuu_runvar. So I'm guessing $qemuu_suffix was just
the value left from a previous call of test_matrix_do_one() with
dom0arch==i386. The new name is already used by "linux-linus" branch.

As for the few changes in {xl,libvirt}-{raw,vhd,qcow2} tests, this is
because of
- f536e834f673 ("make-flight: Trim the matrix of disk format flights")
- 5c70735f177f ("fmtarches: Use dom0arches, not hardcoded arch list")
   > It's not ideal because it means tests jumping about across arches and

So, for those, yes, it's different tests. It adds one "-raw" test, and
otherwise changes the toolstack used for the two other disk formats.

Well, those tests are already in the "linux-linus" branch and the new
"linux-6.1" branch, so we can already check manually if there's a
regression or not. So if they pass in linux-6.1, regression will be
detected, at least in the linux branch.

The rename of the freebsd jobs is unfortunate, but at least, it's going
to be the correct name, instead of having a spurious "-qemuu" suffix.

As for "history of tests " pages, no I don't think we can easly link to
to the previous job name. But that only apply to both freebsd* jobs.

We could keep the -qemuu in freebsd* jobs even if it's misleading to
someone who know what it should mean, that would keep the job name to
all branches and rename it in "linux-linus" branch. I don't know which
one is better.

It just shell script having variable been global by default.

FTAOD, could you mention this in the commit message?

FreeBSD doesn't use `$qemuu_runvar` because it was always using QEMU
upstream (when the FreeBSD test was added we decided to only test with
QEMU upstream).  So there's indeed no `-qemut` variant, but by
dropping the -qemuu prefix it could be confused with a PV guest
based test.

Probably a dummy question, but why haven't those commits changed the
output of make-flight earlier?  I'm fine with the change, but I don't
really get why we are seeing it only now.

I thought "-qemuu" just meant we were using the qemu-upstream as
device-model instead of the default one, but it seems that instead no
jobs are generated with "$qemuu_suffix==''", (or only for Xen 4.2 and
older). So now I guess that all HVM tests have either -qemut or -qemuu.

We that, I guess it makes sense to keep "-qemuu" for freebsd tests. That
would just change branch "linux-linus" and "linux-6.1". I'll prepare a
new patch with that.

Looking at the commit message, they did some changes.

But the second commit might have made changes in a way that wasn't
intended. For example, "xl-raw" test disappear.

First commit intended to have exactly 6 jobs spread across all arches.
It used as input "i386 armhf amd64 armhf" and just check that the arch
corresponded to the current "$dom0arch". The function is called several
time with different $dom0arch.

The second mention commit changes to use $dom0arches which takes
different values " i386 amd64", then " armhf" and " arm64". The extra
space at the beginning of the string is why there's no more "xl-raw"
tests, because now '' became one of the possible dom0arch which of course
it doesn't exist. Then we have the same exact list of 3 test on armhf
and arm64, which defeat the original intention of the first mention
commit.

So, now I feel like I need to rework do_pv_debian_tests() to at least
re-add "xl-raw" test, and maybe keep only 6 toolstack-disk_format tests
spread across all arches? That could maybe reduce the number of tests on
arm64 which is the current bottleneck.
