Revisiting parallel save/restore
by Jim Fehlig 02 May '24

02 May '24

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 [1] https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/3Y5G… [2] https://gitlab.com/qemu-project/qemu/-/blob/master/docs/devel/migration/map…

[PATCH] docs/about: Automatically deprecate versioned machine types older than 6 years
by Thomas Huth 30 Apr '24

30 Apr '24

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 29 Apr '24

29 Apr '24

[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 .gitlab-ci.d/buildtest.yml | 2 +- MAINTAINERS | 1 - docs/about/deprecated.rst | 51 +- docs/about/removed-features.rst | 103 +++ docs/devel/migration/main.rst | 2 +- hw/core/machine.c | 1 - include/migration/misc.h | 6 - meson.build | 2 - meson_options.txt | 2 - migration/block.c | 1019 ------------------------------ migration/block.h | 52 -- migration/colo.c | 1 - migration/meson.build | 4 - migration/migration-hmp-cmds.c | 97 +-- migration/migration.c | 70 +- migration/migration.h | 7 - migration/options.c | 229 ------- migration/ram-compress.c | 564 ----------------- migration/ram.c | 166 +---- migration/savevm.c | 5 - qapi/migration.json | 205 +----- scripts/meson-buildoptions.sh | 4 - tests/qemu-iotests/183 | 147 ----- tests/qemu-iotests/183.out | 66 -- tests/qemu-iotests/common.filter | 7 - tests/qtest/migration-test.c | 139 ---- 26 files changed, 130 insertions(+), 2822 deletions(-) delete mode 100644 migration/block.c delete mode 100644 migration/block.h delete mode 100644 migration/ram-compress.c delete mode 100755 tests/qemu-iotests/183 delete mode 100644 tests/qemu-iotests/183.out base-commit: a118c4aff4087eafb68f7132b233ad548cf16376 -- 2.35.3
