Hi
This series do a lot of much neededs cleanups and fixes to migration-test:
- We make source and target machines coherent/constent
- We make all command line options consistent
- We split test_migrate_start() and test_migrate_end() into:
* guest_start() from from and to. It is the same function, just
defines the basic options. I am open to renaming it to
guest_define() or anything else that people can came with.
* guest_destroy(), you have guessed it, right?
* guest_realize() after guest_start() and adding any options we
need, we just create the guest. We use the same function from
source and target, making inconsistencies disapear.
- uri: right now it is a mess, we can have:
* uri created with migration_start()
* or listen_uri
* or connect_uri
* or by hand
now we just setup to->uri, and we get the migrate uri automatically from there.
- we were creating bootfile for each migration test. Change the code
so we only create it once for the whole migration test.
- Introduce GuestState. Using QTestState directly means that we can
add state by guest, making it abuse local variables. Now we move
all guest state into GuestState.
- Apart from test found by Fabiano, we had another problems with
multifd + cancel:
* We didn't wait for "to" guest to finish before we launch second
target guest "to2". We fixed it by destroying "to" before
launching "to2".
* We reused "dest_serial" filename from "to" and "to2", so in a very
loaded host, it could be that we contact with the wrong vm, and we
never end.
* I change the code so the serial filename is dependent on guest
name, that made changing the interface:
wait_for_serial("dest_serial") to
wait_for_relial(to) (or to2 or ...) so we can't fail.
- we move the global event variables to GuestState, so no more
got_src_stop or got_dst_resume, we just check
who->got_event
- create a function from migrate-incoming, so now we do:
migrate_incoming(uri) and it does what we want/expect.
- vcpu_dirty_limit is not related to migration at all, just is easier
to write with migration infrastructure. Move all useful functions
to migration-helpers.[ch] and split the test into
vcpu-dirty-limit-test.c. I think that we can declare that test slow.
- Now that guest_create/destry exist, we can "reuse" them in
vcpu_dirty_limit test.
- The removal of files, like "migsocket" was flaky at least, i.e. not
always removed. "migsocket-recover" was not even tried to remove.
New code just remove them by default.
- MigrationStart is gone, instead of creating that flags, I just call
functions that do that function.
- if no uri is given for a target guest, it launches with -incoming
defer, that should be the default.
ToDo:
- Tests shouldn't really use QMP, if we need QMP, we should hide it
behind a c function. Almost everything is there now, except things
like "reuse".
- I think we should split auto-converge test:
* we are not testing migration there, we are testing vcpu slowdown
* the test is really slow, see documentation why we can't make it much faster.
- I still need to make test faster with stoping switchover.
Please, review.

It makes no sense that we don't have the same configuration on both sides.

And it needs to be in both source and target, so put it on arch_opts.

The bootsector code is read only from the guest (otherwise we are
going to have problems with it being read from both source and
destination).
Create a single copy for all the tests.

We called migrate_qmp() in lot of places. And there are tricks like
changing tcp address with the right port.
Only two callers remaining:
- postcopy resume: It needs to play with the qmp.
- baddest: We want to do a unvalid URI. For that we need to do it by
hand.

So we don't use a global variable for events. We use one by guest.

So we can get rid of the duplication in test_migrate_start().
- unfold test_migrate_start() because it is just two calls to
guest_realize().
- make dirty_limit test use guest_realize()
- get rid of MigrateStart as now it is empty.

I did in the cover letter, will put that on the commit:
- We used to share dest_serial file for the two targets of migration (to
and to2), where we have a race.
- this series fixes the races in two ways:
* we wait for "to" to finish before we launch "to2", so the race can't
happen.
* One of the reasons why I created GuestState is that I needed a place
to store the serial file name (now I call it "target" and "target2").
- I put on the cover letter that this is not enough, we also need
Fabiano fix for the thread list.
- Peter Mayel was the most vocal about this particular failure, I cc'd
him and asked on the cover letter for the people to used to have
failures to test.
So how should I handled this to be clearer?
Later, Juan.

Details just need to be in the commit message, because cover letters
aren't visible when someone is looking back at 'git log' to find out
why the test was re-enabled.

I hope Laurent can see this one out of 40s.
Makes sense to me, but does it mean that the devices are not matching
before on ppc? Confused how did it work then..

Personally maybe I won't bother with such a patch as a whole.. but if we do
want to, we could also remove "#else" here and move comment above it.

Isn't this adding duplications instead?
Meanwhile, shmem_opts right now is auto-free. If we do this we don't need
it to be auto-free anymore..

This is still under "#if 0" block.. and the old code doesn't even compile,
but the change looks fine.

According to the history:
https://lore.kernel.org/all/20190305180635.GA3803@work-vm/
It's never enabled, and not sure whether Yury followed it up. Juan: have
you tried it out on aarch64 before enabling it again? I assume we rely on
the previous patch but that doesn't even sound like aarch64 specific. I
worry it'll just keep failing on aarch64.
Copy Yury too.

Maybe assert on: "!args->use_shmem || shm_supported()" here?

I agree we need the -nodefaults on both sides.
It has been introduced by
fc71e3e562b7 ("tests/migration: Speed up the test on ppc64") (Thomas)
I think it works because destination side doesn't check for what is missing.

We need.
It can still be from g_strdup_printf().
What this patch change is that it will never be (again) "".
It is going to be NULL or a real string, like all the other options.
The real string is generated, so it needs to be auto_free.
Later, Juan.

Nope.
We are being extra defensive in some tests.
It is tested here

Checking (in the same code path) once in the same file looks like enough
to me.

I am trying that all the options are handled the same.
The whole idea here is that I have to split guest definition and guest
creation. See GuestState later on the series.
If all the options are handled the same, it is much easier than if I
have to do "magic" for one vs others.
One thing that I wonder is that migration-test can't be the only test
that needs to redirect stderr, but that is a completely different issue.

You are right.
do_migrate(from, to, NULL)
Same for the next one.
Too many rebases trying to make things clearer.
Good catch.

This will protect a new test passing in use_shmem=true without checking
shm_supported(). It'll then fail at starting the VM I think otherwise.

Hi
As it should.
Test is wrong and it aborts.
It is not that it has found an error, it is that it is badly written.
And anyways, args->use_shmem dissapears later in the series O:-)
Later, Juan.

Hi
I am resending this series.
I hard tested this time. x86_64 host.
Two build directories:
- x86_64 (I just build qemu-system-x86_64, kvm)
- aarch64 (I just build qemu-system-aarch64, tcg)
Everything is run as:
while true; do $command || break; done
And run this:
- x86_64:
* make check (nit: you can't run two make checks on the same
directory)
* 4 ./test/qtest/migration-test
* 2 ./test/qtest/migration-test -p ./tests/qtest/migration-test -p /x86_64/migration/multifd/tcp/plain/cancel
* 2 ./test/qtest/migration-test -p ./tests/qtest/migration-test -p /x86_64/migration/ignore_shared
- aarch64:
The same with s/x86_64/aarch64/
And left it running for 6 hours. No errors.
Machine has enough RAM for running this (128GB) and 18 cores (intel
i9900K).
Load of the machine while running this tests is around 50 (I really hope
that our CI hosts have less load).
A run master with the same configuration. In less than 10 minutes I get
the dreaded:
# starting QEMU: exec ./qemu-system-aarch64 -qtest unix:/tmp/qtest-3264370.sock -qtest-log /dev/null -chardev socket,path=/tmp/qtest-3264370.qmp,id=char0 -mon chardev=char0,mode=control -display none -accel kvm -accel tcg -machine virt,gic-version=max -name target,debug-threads=on -m 150M -serial file:/tmp/migration-test-1A1461/dest_serial -incoming defer -cpu max -kernel /tmp/migration-test-1A1461/bootsect -accel qtest
Broken pipe
../../../../../mnt/code/qemu/multifd/tests/qtest/libqtest.c:195: kill_qemu() detected QEMU death from signal 6 (Aborted) (core dumped)
Aborted (core dumped)
$
On multifd+cancel.
I have no been able to ever get ignore_shared to fail on my machine.
But I didn't tested aarch64 TCG in the past so hard, and in x86_64 it
has always worked for me.
Later, Juan.

Thanks a lot, Juan.
Do you mean master is broken with QEMU_TEST_FLAKY_TESTS=1? And after the
whole series applied we cannot trigger issue in the few hours test even
with it?
Shall we wait for another 1-2 days to see whether Yury would comment
(before you repost)? Otherwise I agree if it survives your few-hours test
we should give it a try - at least according to Dave's comment before it
was failing easily, but it is not now on the test bed.
Maybe it's still just hidden, but in that case I also agree enabling it in
the repo is the simplest way to reproduce the failure again, if we still
ever want to enable it one day..

Sending v2.
In that serie both re-enablement of multifd+cancel and ingnore_shared
are the last two patches.
So I am going to wait until all other patches are in and that the people
that complained the most: Peter Maydell, Daniel and Thomas say/test on their
cases. Hint, Hint.
Later, Juan.

Yeap. I mean multifd+cancel. That is the reason why we put the FLAKY
part.

Yeap.

From the v2 series that I am about to post:
migration-test: Re-enable multifd_cancel test
Why?
- migration/multifd: Protect accesses to migration_threads
this patch fixed the problem about memory corruption
- migration-test: Move serial to GuestState
now we are using guest name as serial file name
In the past there was a conflict between vm "to" and "to2" that used
the same file name.
- migration-test: Wait for first target to finish
Now we wait from vm "to" to finish before launching "to2". So we
avoid similar problems in the future.

We want. If it still fails, we want to know why and fix it.
Later, Juan.
