These tests 188, 189 and 198 use qemu-io with --image-opts with additional

e7a271bee9 tests/qemu-iotests: Restrict test 156 to the 'file' protocol
The test fails completely when you try to use it with a different
protocol, e.g. with "./check -ssh -qcow2 156".
The test uses some hand-crafted JSON statements which cannot work with other

52df1a5b61 qemu-img: Fix Column Width and Improve Formatting in snapshot list
When running the command `qemu-img snapshot -l SNAPSHOT` the output of
VM_CLOCK (measures the offset between host and VM clock) cannot to
accommodate values in the order of thousands (4-digit).

This line [1] hints on the problem. Additionally, the column width for
the VM_CLOCK field was reduced from 15 to 13 spaces in commit b39847a5
in line [2], resulting in a shortage of space.

[1]:
https://gitlab.com/qemu-project/qemu/-/blob/master/block/qapi.c?ref_type=heads#L753
[2]:
https://gitlab.com/qemu-project/qemu/-/blob/master/block/qapi.c?ref_type=heads#L763

This patch restores the column width to 15 spaces and makes adjustments
to the affected iotests accordingly. Furthermore, addresses a potential
source
of confusion by removing whitespace in column headers. Example, VM CLOCK
is modified to VM_CLOCK. Additionally a '--' symbol is introduced when
ICOUNT returns no output for clarity.

e8fce34ecc iotests: Add test for reset/AioContext switches with NBD exports
This replicates the scenario in which the bug was reported.
Unfortunately this relies on actually executing a guest (so that the
firmware initialises the virtio-blk device and moves it to its
configured iothread), so this can't make use of the qtest accelerator
like most other test cases. I tried to find a different easy way to
trigger the bug, but couldn't find one.

cc29c12ec6 iotests: Make 144 deterministic again
Since commit effd60c8 changed how QMP commands are processed, the order
of the block-commit return value and job events in iotests 144 wasn't
fixed and more and caused the test to fail intermittently.

Change the test to cache events first and then print them in a
predefined order.

Waiting three times for JOB_STATUS_CHANGE is a bit uglier than just
waiting for the JOB_STATUS_CHANGE that has "status": "ready", but the
tooling we have doesn't seem to allow the latter easily.

c645bac4e0 iotests: fix leak of tmpdir in dry-run mode
Creating an instance of the 'TestEnv' class will create a temporary
directory. This dir is only deleted, however, in the __exit__ handler
invoked by a context manager.

In dry-run mode, we don't use the TestEnv via a context manager, so
were leaking the temporary directory. Since meson invokes 'check'
5 times on each configure run, developers /tmp was filling up with
empty temporary directories.

effd60c878 monitor: only run coroutine commands in qemu_aio_context
monitor_qmp_dispatcher_co() runs in the iohandler AioContext that is not
polled during nested event loops. The coroutine currently reschedules
itself in the main loop's qemu_aio_context AioContext, which is polled
during nested event loops. One known problem is that QMP device-add
calls drain_call_rcu(), which temporarily drops the BQL, leading to all
sorts of havoc like other vCPU threads re-entering device emulation code
while another vCPU thread is waiting in device emulation code with
aio_poll().

Paolo Bonzini suggested running non-coroutine QMP handlers in the
iohandler AioContext. This avoids trouble with nested event loops. His
original idea was to move coroutine rescheduling to
monitor_qmp_dispatch(), but I resorted to moving it to qmp_dispatch()
because we don't know if the QMP handler needs to run in coroutine
context in monitor_qmp_dispatch(). monitor_qmp_dispatch() would have
been nicer since it's associated with the monitor implementation and not
as general as qmp_dispatch(), which is also used by qemu-ga.

A number of qemu-iotests need updated .out files because the order of
QMP events vs QMP responses has changed.

Solves Issue #1933.

9ee2dd4c22 iotests: port 141 to Python for reliable QMP testing
The common.qemu bash functions allow tests to interact with the QMP
monitor of a QEMU process. I spent two days trying to update 141 when
the order of the test output changed, but found it would still fail
occassionally because printf() and QMP events race with synchronous QMP
communication.

I gave up and ported 141 to the existing Python API for QMP tests. The
Python API is less affected by the order in which QEMU prints output
because it does not print all QMP traffic by default.

The next commit changes the order in which QMP messages are received.
Make 141 reliable first.

23c983c8f6 block: remove outdated AioContext locking comments
The AioContext lock no longer exists.

There is one noteworthy change:

  - * More specifically, these functions use BDRV_POLL_WHILE(bs), which
  - * requires the caller to be either in the main thread and hold
  - * the BlockdriverState (bs) AioContext lock, or directly in the
  - * home thread that runs the bs AioContext. Calling them from
  - * another thread in another AioContext would cause deadlocks.

I am not sure whether deadlocks are still possible. Maybe they have just
moved to the fine-grained locks that have replaced the AioContext. Since
I am not sure if the deadlocks are gone, I have kept the substance
unchanged and just removed mention of the AioContext.

We have a few test cases that include tests for corner case aspects of
internal snapshots, but nothing that tests that they actually function
as snapshots or that involves deleting a snapshot. Add a test for this
kind of basic internal snapshot functionality.

3b7094fe83 iotests: fix default machine type detection
The machine type is being detected based on "-M help" output, and we're
searching for the line ending with " (default)".  However, in downstream
one of the machine types s marked as deprecated might become the
default, in which case this logic breaks as the line would now end with
" (default) (deprecated)".  To fix potential issues here, let's relax
that requirement and detect the mere presence of " (default)" line
instead.

8f37120383 iotests: Test two stream jobs in a single iothread
This tests two parallel stream jobs that will complete around the same
time and run on two different disks in the same iothreads. It is loosely
based on the bug report at https://issues.redhat.com/browse/RHEL-1761.

For me, this test hangs reliably with the originally reported bug in
blk_remove_bs(). After fixing it, it intermittently hangs for the bugs
fixed after it, missing AioContext unlocking in bdrv_graph_wrunlock()
and in stream_prepare(). The deadlocks seem to happen more frequently
when the test directory is on tmpfs.

900e7d413d iotests: add test for changing mirror's copy_mode
One part of the test is using a throttled source to ensure that there
are no obvious issues when changing the copy_mode while there are
ongoing requests (source and target images are compared at the very
end).

The other part of the test is using a throttled target to ensure that
the change to active mode actually happened. This is done by hitting
the throttling limit, issuing a synchronous write and then immediately
verifying the target side. QSD is used, because otherwise, a
synchronous write would hang there.

76cb2f2491 mirror: return mirror-specific information upon query
To start out, only actively-synced is returned.

For example, this is useful for jobs that started out in background
mode and switched to active mode. Once actively-synced is true, it's
clear that the mode switch has been completed. Note that completion of
the switch might happen much earlier, e.g. if the switch happens
before the job is ready, once all background operations have finished.
It's assumed that whether the disks are actively-synced or not is more
interesting than whether the mode switch completed. That information
can still be added if required in the future.

In presence of an iothread, the actively_synced member is now shared
between the iothread and the main thread, so turn accesses to it
atomic.

Requires to adapt the output for iotest 109.

87fe52ceca iotests: add tests for "qemu-img rebase" with compression
The test cases considered so far:

314 (new test suite):

1. Check that compression mode isn't compatible with "-f raw" (raw
   format doesn't support compression).
2. Check that rebasing an image onto no backing file preserves the data
   and writes the copied clusters actually compressed.
3. Same as 2, but with a raw backing file (i.e. the clusters copied from the
   backing are originally uncompressed -- we check they end up compressed
   after being merged).
4. Remove a single delta from a backing chain, perform the same checks
   as in 2.
5. Check that even when backing and overlay are initially uncompressed,
   copied clusters end up compressed when rebase with compression is
   performed.

271:

1. Check that when target image has subclusters, rebase with compression
   will make an entire cluster containing the written subcluster
   compressed.
