[libvirt RFCv10 00/32] multifd save restore prototype
by Claudio Fontana 15 May '22

15 May '22

This is v10 of the multifd save prototype, which improves the DIRECT I/O APIs and makes changes to the on disk format backward and forward compatible, avoiding the need to alter the QEMU_SAVE_VERSION. This series demonstrates the DIRECT I/O friendly read/write code working by using the block-friently multifd streams supplied by the multifd helper, but could also work with block-aware QEMU streams if ever available in the future. KNOWN ISSUES: a) still applies only to save/restore (no managed save etc) b) multifd: saves to multiple files instead of just one file --- changes from v9: * exposed virFileDirectAlign * separated the >= 2 QEMU_SAVE_VERSION change in own patch * reworked the write code to add the alignment padding to the data_len, making the on disk format compatible when loaded from an older libvirt. * reworked the read code to use direct I/O APIs only for actual direct I/O file descriptors, so as to make old images work with newer libvirt. --- changes from v8: * rebased on master * reordered patches to add more upstreamable content at the start * split introduction of virQEMUSaveFd, so the first part is multifd-free * new virQEMUSaveDataRead as a mirror of virQEMUSaveDataWrite * introduced virFileDirect API, using it in virFileDisk operations and for virQEMUSaveRead and virQEMUSaveWrite --- changes from v7: * [ base params API and iohelper refactoring upstreamed ] * extended the QEMU save image format more, to record the nr of multifd channels on save. Made the data header struct packed. * removed --parallel-connections from the restore command, as now it is useless due to QEMU save image format extension. * separate out patches to expose migration_params APIs to saveimage, including qemuMigrationParamsSetString, SetCap, SetInt. * fixed bugs in the ImageOpen patch (missing saveFd init), removed some whitespace, and fixed some convoluted code paths for return value -3. --- changes from v6: * improved error path handling, with error messages and especially cancellation of qemu process on error during restore. * split patches more and reordered them to keep general refactoring at the beginning before the --parallel stuff is introduced. * improved multifd compression support, including adding an enum and extending the QEMU save image format to record the compression used on save, and pick it up automatically on restore. --- changes from v4: * runIO renamed to virFileDiskCopy and rethought arguments * renamed new APIs from ...ParametersFlags to ...Params * introduce the new virDomainSaveParams and virDomainRestoreParams without any additional parameters, so they can be upstreamed first. * solved the issue in the gendispatch.pl script generating code that was missing the conn parameter. --- changes from v3: * reordered series to have all helper-related change at the start * solved all reported issues from ninja test, including documentation * fixed most broken migration capabilities code (still imperfect likely) * added G_GNUC_UNUSED as needed * after multifd restore, added what I think were the missing operations: qemuProcessRefreshState(), qemuProcessStartCPUs() - most importantly, virDomainObjSave() The domain now starts running after restore without further encouragement * removed the sleep(10) from the multifd-helper --- changes from v2: * added ability to restore the VM from disk using multifd * fixed the multifd-helper to work in both directions, assuming the need to listen for save, and connect for restore. * fixed a large number of bugs, and probably introduced some :-) --- Claudio Fontana (32): virfile: introduce virFileDirect APIs virfile: use virFileDirect API in runIOCopy qemu: saveimage: rework image read/write to be O_DIRECT friendly qemu: saveimage: assume future formats will also support compression virfile: virFileDiskCopy: prepare for O_DIRECT files without wrapper qemu: saveimage: introduce virQEMUSaveFd qemu: saveimage: convert qemuSaveImageCreate to use virQEMUSaveFd qemu: saveimage: convert qemuSaveImageOpen to use virQEMUSaveFd tools: prepare doSave to use parameters tools: prepare cmdRestore to use parameters libvirt: add new VIR_DOMAIN_SAVE_PARALLEL flag and parameter qemu: add stub support for VIR_DOMAIN_SAVE_PARALLEL in save qemu: add stub support for VIR_DOMAIN_SAVE_PARALLEL in restore multifd-helper: new helper for parallel save/restore qemu: saveimage: add virQEMUSaveFd APIs for multifd qemu: saveimage: wire up saveimage code with the multifd helper qemu: capabilities: add multifd to the probed migration capabilities qemu: saveimage: add multifd related fields to save format qemu: migration_params: add APIs to set Int and Cap qemu: migration: implement qemuMigrationSrcToFilesMultiFd for save qemu: add parameter to qemuMigrationDstRun to skip waiting qemu: implement qemuSaveImageLoadMultiFd for restore tools: add parallel parameter to virsh save command tools: add parallel parameter to virsh restore command qemu: add migration parameter multifd-compression libvirt: add new VIR_DOMAIN_SAVE_PARAM_PARALLEL_COMPRESSION qemu: saveimage: add parallel compression argument to ImageCreate qemu: saveimage: add stub support for multifd compression parameter qemu: migration: expose qemuMigrationParamsSetString qemu: saveimage: implement multifd-compression in parallel save qemu: saveimage: restore compressed parallel images tools: add parallel-compression parameter to virsh save command docs/manpages/virsh.rst | 39 +- include/libvirt/libvirt-domain.h | 29 + po/POTFILES.in | 1 + src/libvirt_private.syms | 9 + src/qemu/qemu_capabilities.c | 4 + src/qemu/qemu_capabilities.h | 2 + src/qemu/qemu_driver.c | 146 ++-- src/qemu/qemu_migration.c | 160 ++-- src/qemu/qemu_migration.h | 16 +- src/qemu/qemu_migration_params.c | 71 +- src/qemu/qemu_migration_params.h | 15 + src/qemu/qemu_process.c | 3 +- src/qemu/qemu_process.h | 5 +- src/qemu/qemu_saveimage.c | 793 ++++++++++++++---- src/qemu/qemu_saveimage.h | 71 +- src/qemu/qemu_snapshot.c | 6 +- src/util/meson.build | 16 + src/util/multifd-helper.c | 247 ++++++ src/util/virfile.c | 316 ++++++- src/util/virfile.h | 11 + src/util/virthread.c | 5 + src/util/virthread.h | 1 + .../caps_4.0.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_4.0.0.ppc64.xml | 1 + .../caps_4.0.0.riscv32.xml | 1 + .../caps_4.0.0.riscv64.xml | 1 + .../qemucapabilitiesdata/caps_4.0.0.s390x.xml | 1 + .../caps_4.0.0.x86_64.xml | 1 + .../caps_4.1.0.x86_64.xml | 1 + .../caps_4.2.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_4.2.0.ppc64.xml | 1 + .../qemucapabilitiesdata/caps_4.2.0.s390x.xml | 1 + .../caps_4.2.0.x86_64.xml | 1 + .../caps_5.0.0.aarch64.xml | 2 + .../qemucapabilitiesdata/caps_5.0.0.ppc64.xml | 2 + .../caps_5.0.0.riscv64.xml | 2 + .../caps_5.0.0.x86_64.xml | 2 + .../qemucapabilitiesdata/caps_5.1.0.sparc.xml | 2 + .../caps_5.1.0.x86_64.xml | 2 + .../caps_5.2.0.aarch64.xml | 2 + .../qemucapabilitiesdata/caps_5.2.0.ppc64.xml | 2 + .../caps_5.2.0.riscv64.xml | 2 + .../qemucapabilitiesdata/caps_5.2.0.s390x.xml | 2 + .../caps_5.2.0.x86_64.xml | 2 + .../caps_6.0.0.aarch64.xml | 2 + .../qemucapabilitiesdata/caps_6.0.0.s390x.xml | 2 + .../caps_6.0.0.x86_64.xml | 2 + .../caps_6.1.0.x86_64.xml | 2 + .../caps_6.2.0.aarch64.xml | 2 + .../qemucapabilitiesdata/caps_6.2.0.ppc64.xml | 2 + .../caps_6.2.0.x86_64.xml | 2 + .../caps_7.0.0.aarch64.xml | 2 + .../qemucapabilitiesdata/caps_7.0.0.ppc64.xml | 2 + .../caps_7.0.0.x86_64.xml | 2 + .../caps_7.1.0.x86_64.xml | 2 + tools/virsh-domain.c | 101 ++- 56 files changed, 1718 insertions(+), 404 deletions(-) create mode 100644 src/util/multifd-helper.c -- 2.35.3

[libvirt RFCv9 00/31] multifd save restore prototype
by Claudio Fontana 15 May '22

15 May '22

This is v9 of the multifd save prototype, which splits things up more in order to hopefully offer more upstreamable code, and adds DIRECT I/O APIs and changes to the save/restore format to be more block friendly, potentially removing the need of an iohelper completely. This is demonstrated in this case using the multifd streams supplied by the multifd helper, but could also work with block-aware QEMU streams if ever available in the future. KNOWN ISSUES: a) still applies only to save/restore (no managed save etc) b) multifd: saves to multiple files instead of just one file --- changes from v8: * rebased on master * reordered patches to add more upstreamable content at the start * split introduction of virQEMUSaveFd, so the first part is multifd-free * new virQEMUSaveDataRead as a mirror of virQEMUSaveDataWrite * introduced virFileDirect API, using it in virFileDisk operations and for virQEMUSaveRead and virQEMUSaveWrite --- changes from v7: * [ base params API and iohelper refactoring upstreamed ] * extended the QEMU save image format more, to record the nr of multifd channels on save.

[PATCH 00/37] qemu: Improve 'qemuFDPass' usability and refactor interface code to use it
by Peter Krempa 13 May '22

13 May '22

This series modifies qemuFDPass to be a bit more convenient to use by e.g. remembering the maximum fd set index currently used across libvirtd restarts so that we can avoid having to pass the FDs before actually constructing the device properties. Along with that this code refactors the handling of FDs used for network interfaces. There was a substantial amount of duplicated code with plethora of helper variables and such. By converting to qemuFDPass stored in the private data we can simplify the functions.

This series fixes routed networks when a newer firewalld (>= 1.0.0) is present [1]. Firewalld 1.0.0 included a change that disallows implicit forwarding between zones [2]. libvirt was relying on this behavior to allow routed networks to function. New firewalld policies are added. This is done to use common rules between NAT and routed networks. Policies have been supported since firewalld 0.9.0.
