47b2c3d4f6 tests/qtest/migration: Add a wrapper to print test names
Our usage of gtest results in us losing the very basic functionality
of "knowing which test failed". The issue is that gtest only prints
test names ("paths" in gtest parlance) once the test has finished, but
we use asserts in the tests and crash gtest itself before it can print
anything. We also use a final abort when the result of g_test_run is
not 0.

Depending on how the test failed/broke we can see the function that
trigged the abort, which may be representative of the test, but it
could also just be some generic function.

We have been relying on the primitive method of looking at the name of
the previous successful test and then looking at the code to figure
out which test should have come next.

Add a wrapper to the test registration that does the job of printing
the test name before running.

086d8dc142 tests/qtest: Add a test for fixed-ram with passing of fds
Add a multifd test for fixed-ram with passing of fds into QEMU. This
is how libvirt will consume the feature.

There are a couple of details to the fdset mechanism:

- multifd needs two distinct file descriptors (not duplicated with
  dup()) on the outgoing side so it can enable O_DIRECT only on the
  channels that write with alignment. The dup() system call creates
  file descriptors that share status flags, of which O_DIRECT is one.

  the incoming side doesn't set O_DIRECT, so it can dup() fds and
  therefore can receive only one in the fdset.

- the open() access mode flags used for the fds passed into QEMU need
  to match the flags QEMU uses to open the file. Currently O_WRONLY
  for src and O_RDONLY for dst.

O_DIRECT is not supported on all systems/filesystems, so run the fdset
test without O_DIRECT if that's the case. The migration code should
still work in that scenario.

4b6eeb2335 migration: Add support for fdset with multifd + file
Allow multifd to use an fdset when migrating to a file. This is useful
for the scenario where the management layer wants to have control over
the migration file.

By receiving the file descriptors directly, QEMU can delegate some
high level operating system operations to the management layer (such
as mandatory access control).

The management layer might also want to add its own headers before the
migration stream.

Enable the "file:/dev/fdset/#" syntax for the multifd migration with
fixed-ram. The fdset should contain two fds on the source side of
migration and 1 fd on the destination side. The two fds should not be
duplicates between themselves.

Multifd enables O_DIRECT on the source side using one of the fds and
keeps the other without the flag. None of the fds should have the
O_DIRECT flag already set.

The fdset mechanism also requires that the open() access mode flags be
the same as what QEMU uses internally: WRONLY for the source fds and
RDONLY for the destination fds.

2cb56cb34e monitor: fdset: Match against O_DIRECT
We're about to enable the use of O_DIRECT in the migration code and
due to the alignment restrictions imposed by filesystems we need to
make sure the flag is only used when doing aligned IO.

The migration will do parallel IO to different regions of a file, so
we need to use more than one file descriptor. Those cannot be obtained
by duplicating (dup()) since duplicated file descriptors share the
file status flags, including O_DIRECT. If one migration channel does
unaligned IO while another sets O_DIRECT to do aligned IO, the
filesystem would fail the unaligned operation.

The add-fd QMP command along with the fdset code are specifically
designed to allow the user to pass a set of file descriptors with
different access flags into QEMU to be later fetched by code that
needs to alternate between those flags when doing IO.

Extend the fdset matching function to behave the same with the
O_DIRECT flag.

4478aef543 monitor: Honor QMP request for fd removal immediately
We're currently only removing an fd from the fdset if the VM is
running. This causes a QMP call to "remove-fd" to not actually remove
the fd if the VM happens to be stopped.

While the fd would eventually be removed when monitor_fdset_cleanup()
is called again, the user request should be honored and the fd
actually removed. Calling remove-fd + query-fdset shows a recently
removed fd still present.

The runstate_is_running() check was introduced by commit ebe52b592d
("monitor: Prevent removing fd from set during init"), which by the
shortlog indicates that they were trying to avoid removing an
yet-unduplicated fd too early.

I don't see why an fd explicitly removed with qmp_remove_fd() should
be under runstate_is_running(). I'm assuming this was a mistake when
adding the parenthesis around the expression.

Move the runstate_is_running() check to apply only to the
QLIST_EMPTY(dup_fds) side of the expression and ignore it when
mon_fdset_fd->removed has been explicitly set.

db401f5302 migration/multifd: Support incoming fixed-ram stream format
For the incoming fixed-ram migration we need to read the ramblock
headers, get the pages bitmap and send the host address of each
non-zero page to the multifd channel thread for writing.

To read from the migration file we need a preadv function that can
read into the iovs in segments of contiguous pages because (as in the
writing case) the file offset applies to the entire iovec.

Usage on HMP is:

(qemu) migrate_set_capability multifd on
(qemu) migrate_set_capability fixed-ram on
(qemu) migrate_set_parameter max-bandwidth 0

ed95cd0446 migration/multifd: Support outgoing fixed-ram stream format
The new fixed-ram stream format uses a file transport and puts ram
pages in the migration file at their respective offsets and can be
done in parallel by using the pwritev system call which takes iovecs
and an offset.

Add support to enabling the new format along with multifd to make use
of the threading and page handling already in place.

This requires multifd to stop sending headers and leaving the stream
format to the fixed-ram code. When it comes time to write the data, we
need to call a version of qio_channel_write that can take an offset.

Usage on HMP is:

(qemu) stop
(qemu) migrate_set_capability multifd on
(qemu) migrate_set_capability fixed-ram on
(qemu) migrate_set_parameter max-bandwidth 0

d5bce67e17 migration/ram: Ignore multifd flush when doing fixed-ram migration
Some functionalities of multifd are incompatible with the 'fixed-ram'
migration format.

The MULTIFD_FLUSH flag in particular is not used because in fixed-ram
there is no sinchronicity between migration source and destination so
there is not need for a sync packet. In fact, fixed-ram disables
packets in multifd as a whole.

Make sure RAM_SAVE_FLAG_MULTIFD_FLUSH is never emitted when fixed-ram
is enabled.

6822813ae9 migration/multifd: Allow receiving pages without packets
Currently multifd does not need to have knowledge of pages on the
receiving side because all the information needed is within the
packets that come in the stream.

We're about to add support to fixed-ram migration, which cannot use
packets because it expects the ramblock section in the migration file
to contain only the guest pages data.

Add a data structure to transfer pages between the ram migration code
and the multifd receiving threads.

We don't want to reuse MultiFDPages_t for two reasons:

a) multifd threads don't really need to know about the data they're
   receiving.

b) the receiving side has to be stopped to load the pages, which means
   we can experiment with larger granularities than page size when
   transferring data.

to be able to accept an iovec array with non-contiguous data.

Add a pwritev and preadv version that splits the array into contiguous

Since iovs can be non contiguous, we'd need a separate array on the
side to carry an extra file offset for each of them, so I'm relying on
the fact that iovs are all within a same host page and passing in an
encoded offset that takes the host page into account.

enabling the fixed-ram migration stream format which expects a
seekable transport.

The QIOChannel read and write methods will use the preadv/pwritev

reuse the fd without re-opening for every channel.

Note that this is just setup code and multifd cannot yet make use of

ffd3e56398 migration/multifd: Allow multifd without packets
For the upcoming support to the new 'fixed-ram' migration stream
format, we cannot use multifd packets because each write into the
ramblock section in the migration file is expected to contain only the
guest pages. They are written at their respective offsets relative to
the ramblock section header.

There is no space for the packet information and the expected gains
from the new approach come partly from being able to write the pages
sequentially without extraneous data in between.

The new format also doesn't need the packets and all necessary
information can be taken from the standard migration headers with some
(future) changes to multifd code.

Use the presence of the fixed-ram capability to decide whether to send
packets. For now this has no effect as fixed-ram cannot yet be enabled
with multifd.

43ad5422c9 migration/ram: Add support for 'fixed-ram' outgoing migration
Implement the outgoing migration side for the 'fixed-ram' capability.

A bitmap is introduced to track which pages have been written in the
migration file. Pages are written at a fixed location for every
ramblock. Zero pages are ignored as they'd be zero in the destination
migration as well.

The migration stream is altered to put the dirty pages for a ramblock
after its header instead of having a sequential stream of pages that
follow the ramblock headers. Since all pages have a fixed location,
RAM_SAVE_FLAG_EOS is no longer generated on every migration iteration.

Without fixed-ram (current):        With fixed-ram (new):

07acf019b1 migration/ram: Introduce 'fixed-ram' migration capability
Add a new migration capability 'fixed-ram'.

The core of the feature is to ensure that each RAM page has a specific
offset in the resulting migration stream. The reasons why we'd want
such behavior are:

 - The resulting file will have a bounded size, since pages which are
   dirtied multiple times will always go to a fixed location in the
   file, rather than constantly being added to a sequential
   stream. This eliminates cases where a VM with, say, 1G of RAM can
   result in a migration file that's 10s of GBs, provided that the
   workload constantly redirties memory.

 - It paves the way to implement O_DIRECT-enabled save/restore of the
   migration stream as the pages are ensured to be written at aligned
   offsets.

 - It allows the usage of multifd so we can write RAM pages to the
   migration file in parallel.

For now, enabling the capability has no effect. The next couple of
patches implement the core functionality.

indicated by $TMPC.
Python virtual environments and the build process
-------------------------------------------------
An important step in ``configure`` is to create a Python virtual
environment (venv) during the configuration phase. The Python interpreter
comes from the ``--python`` command line option, the ``$PYTHON`` variable
from the environment, or the system PATH, in this order. The venv resides
in the ``pyvenv`` directory in the build tree, and provides consistency
in how the build process runs Python code.
At this stage, ``configure`` also queries the chosen Python interpreter
about QEMU's build dependencies. Note that the build process does *not*
look for ``meson``, ``sphinx-build`` or ``avocado`` binaries in the PATH;
likewise, there are no options such as ``--meson`` or ``--sphinx-build``.
This avoids a potential mismatch, where Meson and Sphinx binaries on the
PATH might operate in a different Python environment than the one chosen
by the user during the build process. On the other hand, it introduces
a potential source of confusion where the user installs a dependency but
``configure`` is not able to find it. When this happens, the dependency
was installed in the ``site-packages`` directory of another interpreter,
or with the wrong ``pip`` program.
If a package is available for the chosen interpreter, ``configure``
prepares a small script that invokes it from the venv itself[#distlib]_.
If not, ``configure`` can also optionally install dependencies in the
virtual environment with ``pip``, either from wheels in ``python/wheels``
or by downloading the package with PyPI. Downloading can be disabled with
``--disable-download``; and anyway, it only happens when a ``configure``
option (currently, only ``--enable-docs``) is explicitly enabled but
the dependencies are not present[#pip]_.
.. [#distlib] The scripts are created based on the package's metadata,
specifically the ``console_script`` entry points. This is the
same mechanism that ``pip`` uses when installing a package.
Currently, in all cases it would be possible to use ``python -m``
instead of an entry point script, which makes this approach a
bit overkill. On the other hand, creating the scripts is
future proof and it makes the contents of the ``pyvenv/bin``
directory more informative. Portability is also not an issue,
because the Python Packaging Authority provides a package
``distlib.scripts`` to perform this task.
.. [#pip] ``pip`` might also be used when running ``make check-avocado``
if downloading is enabled, to ensure that Avocado is
available.
The required versions of the packages are stored in a configuration file
``pythondeps.toml``. The format is custom to QEMU, but it is documented
at the top of the file itself and it should be easy to understand. The
requirements should make it possible to use the version that is packaged
that is provided by supported distros.
When dependencies are downloaded, instead, ``configure`` uses a "known
good" version that is also listed in ``pythondeps.toml``. In this
scenario, ``pythondeps.toml`` behaves like the "lock file" used by
``cargo``, ``poetry`` or other dependency management systems.
Bundled Python packages
-----------------------
Python packages that are **mandatory** dependencies to build QEMU,
but are not available in all supported distros, are bundled with the
QEMU sources. Currently this includes Meson (outdated in CentOS 8
and derivatives, Ubuntu 20.04 and 22.04, and openSUSE Leap) and tomli
(absent in Ubuntu 20.04).
If you need to update these, please do so by modifying and rerunning
``python/scripts/vendor.py``. This script embeds the sha256 hash of
package sources and checks it. The pypi.org web site provides an easy
way to retrieve the sha256 hash of the sources.

Fixed-ram format
----------------
When the ``fixed-ram`` capability is enabled, a slightly different
stream format is used for the RAM section. Instead of having a
sequential stream of pages that follow the RAMBlock headers, the dirty
pages for a RAMBlock follow its header. This ensures that each RAM
page has a fixed offset in the resulting migration file.
The ``fixed-ram`` capability must be enabled in both source and
destination with:
``migrate_set_capability fixed-ram on``
Since pages are written to their relatives offsets and out of order
(due to the memory dirtying patterns), streaming channels such as
sockets are not supported. A seekable channel such as a file is
required. This can be verified in the QIOChannel by the presence of
the QIO_CHANNEL_FEATURE_SEEKABLE. In more practical terms, this
migration format requires the ``file:`` URI when migrating.

usually expose real issues that are rarely seen on developer machines
due to the constraints of the CI environment. If you encounter a
similar situation then raise a bug and then mark the test as shown on
the code snippet below:

A number of tests are flagged to not run on the GitLab CI. Usually because
they proved to the flaky or there are constraints on the CI environment which
would make them fail. If you encounter a similar situation then use that
variable as shown on the code snippet below to skip the test:

This machine is a little unusual compared to others as QEMU just acts
as an IOREQ server to register/connect with Xen Hypervisor. Control of
the VMs themselves is left to the Xen tooling.
When TPM is enabled, this machine also creates a tpm-tis-device at a user input
tpm base address, adds a TPM emulator and connects to a swtpm application
running on host machine via chardev socket. This enables xenpvh to support TPM
functionalities for a guest domain.

user input tpm base address, adds a TPM emulator and connects to a

More information about TPM use and installing swtpm linux application
can be found in the :ref:`tpm-device` section.
More information about TPM use and installing swtpm linux application can be

Example for starting swtpm on host machine:
