[PATCH v4 20/22] hw/i386/pc: Remove deprecated pc-i440fx-2.3 machine
by Philippe Mathieu-Daudé
The pc-i440fx-2.3 machine was deprecated for the 8.2
release (see commit c7437f0ddb "docs/about: Mark the
old pc-i440fx-2.0 - 2.3 machine types as deprecated"),
time to remove it.

[PATCH] scripts/meson-dist.py: Git builddir from env too
by Michal Privoznik
When meson runs a dist script it set both MESON_BUILD_ROOT and
MESON_DIST_ROOT envvars [1]. But for some reason, we took the
former as an argument and obtained the latter via env.
Well, obtain both via env.
1: https://mesonbuild.com/Reference-manual_builtin_meson.html#mesonadd_dist_...
Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com>

Another option is to pass both directories as arguments. But this
inconsistent solution bothers me. Especially since I want to copy the
script somewhere else (stay tuned to learn more).

Revisiting parallel save/restore
by Jim Fehlig
Hi All,
While Fabiano has been working on improving save/restore performance in qemu,
I've been tinkering with the same in libvirt. The end goal is to introduce a new
VIR_DOMAIN_SAVE_PARALLEL flag for save/restore, along with a
VIR_DOMAIN_SAVE_PARAM_PARALLEL_CONNECTIONS parameter to specify the number of
concurrent channels used for the save/restore. Recall Claudio previously posted
a patch series implementing parallel save/restore completely in libvirt, using
qemu's multifd functionality [1].
A good starting point on this journey is supporting the new mapped-ram
capability in qemu 9.0 [2]. Since mapped-ram is a new on-disk format, I assume
we'll need a new QEMU_SAVE_VERSION 3 when using it? Otherwise I'm not sure how
to detect if a saved image is in mapped-ram format vs the existing, sequential
stream format.
IIUC, mapped-ram cannot be used with the exiting 'fd:' migration URI and instead
must use 'file:'. Does qemu advertise support for that? I couldn't find it. If
not, 'file:' (available in qemu 8.2) predates mapped-ram, so in theory we could
live without the advertisement.
It's also not clear when we want to enable the mapped-ram capability. Should it
always be enabled if supported by the underlying qemu? One motivation for
creating the mapped-ram was to support direct-io of the migration stream in
qemu, in which case it could be tied to VIR_DOMAIN_SAVE_BYPASS_CACHE. E.g. the
mapped-ram capability is enabled when user specifies
VIR_DOMAIN_SAVE_BYPASS_CACHE && user-provided path results in a seekable fd &&
qemu supports mapped-ram?
Looking ahead, should the mapped-ram capability be required for supporting the
VIR_DOMAIN_SAVE_PARALLEL flag? As I understand, parallel save/restore was
another motivation for creating the mapped-ram feature. It allows multifd
threads to write exclusively to the offsets provided by mapped-ram. Can multiple
multifd threads concurrently write to an fd without mapped-ram?
Regards,
Jim

[PATCH] docs/about: Automatically deprecate versioned machine types older than 6 years
by Thomas Huth
Old machine types often have bugs or work-arounds that affect our
possibilities to move forward with the QEMU code base (see for example
https://gitlab.com/qemu-project/qemu/-/issues/2213 for a bug that likely
cannot be fixed without breaking live migration with old machine types,
or https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04516.html or
commit ea985d235b86). So instead of going through the process of manually
deprecating old machine types again and again, let's rather add an entry
that can stay, which declares that machine types older than 6 years are
considered as deprecated automatically. Six years should be sufficient to
support the release cycles of most Linux distributions.

[PATCH v2 0/6] migration removals & deprecations
by Fabiano Rosas
[respinning because master moved and there were conflicts]
Hi everyone,
Here's some cleaning up of deprecated code. It removes the old block
migration and compression code. Both have suitable replacements in the
form of the blockdev-mirror driver and multifd compression,
respectively.
There's also a deprecation for fd: + file to cope with the fact that
the new MigrationAddress API defines transports instead of protocols
(loose terms) like the old string API did. So we cannot map 1:1 from
fd: to any transport because fd: allows *both* file migration and
socket migration.
v1:
https://lore.kernel.org/r/20240425150939.19268-1-farosas@suse.de
Fabiano Rosas (6):
migration: Remove 'skipped' field from MigrationStats
migration: Remove 'inc' option from migrate command
migration: Remove 'blk/-b' option from migrate commands
migration: Remove block migration
migration: Remove non-multifd compression
migration: Deprecate fd: for file migration
