[libvirt] [PATCH v6 0/9] Incremental backups, focus on API
by Eric Blake 27 Mar '19

27 Mar '19

I'm fairly confident that these API are ready to go (that is, I've got qemu code in the wings to implement these API for the qemu driver, as demonstrated at last KVM forum, and it shouldn't be too hard to add support in the test driver to get some 'make check' coverage similar to what I recently added for snapshots). I'm hoping the APIs make it in for 5.2, even if I'm still dealing with review churn on the later parts of my v5 series (there has been a lot of rebasing from earlier review comments, so v5 is currently still the most recent version that I was able to run demos with, although I hope to post the rest of v6 soon). The biggest diffs compared to v4/v5 are addressing many of John Ferlan's grammar suggestions, removing some TODO items from the public API (although implementing those changes, such as the new VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE, is still on my todo list), splitting some large patches (checkpoints and backups are now separated), moving the backup APIs into libvirt-domain.c instead of piggybacking on libvirt-domain-checkpoint.c, and adding 2 more API (virDomainSnapshotCreateXML2 to create a checkpoint at the same time as a snapshot; virDomainListJobIds to learn the job ids of all currently running backup jobs [the initial implementation will only ever have job id 1 due to qemu 4.0 limitations, but the API was designed with future expansion in mind]). I've also got some preliminary patches to snapshot in this posting based on things noticed while working checkpoints. 001/9:[down] 'Revert "snapshot: Add virDomainSnapshotObjListParse"' 002/9:[down] 'Revert "snapshot: Add virDomainSnapshotObjListFormat"' 003/9:[down] 'snapshot: Various doc tweaks' 004/9:[0005] [FC] 'backup: Introduce virDomainCheckpointPtr' 005/9:[down] 'backup: Document new XML for checkpoints' 006/9:[0562] [FC] 'backup: Document new XML for backups' 007/9:[0173] [FC] 'backup: Introduce virDomainCheckpoint APIs' 008/9:[0296] [FC] 'backup: Introduce virDomainBackup APIs' 009/9:[0039] [FC] 'backup: Document nuances between different state capture APIs' Eric Blake (9): Revert "snapshot: Add virDomainSnapshotObjListParse" Revert "snapshot: Add virDomainSnapshotObjListFormat" snapshot: Various doc tweaks backup: Introduce virDomainCheckpointPtr backup: Document new XML for checkpoints backup: Document new XML for backups backup: Introduce virDomainCheckpoint APIs backup: Introduce virDomainBackup APIs backup: Document nuances between different state capture APIs include/libvirt/virterror.h | 7 +- src/util/virerror.c | 12 +- include/libvirt/libvirt-domain-checkpoint.h | 161 ++++ include/libvirt/libvirt-domain-snapshot.h | 7 +- include/libvirt/libvirt-domain.h | 59 +- include/libvirt/libvirt.h | 3 +- src/conf/snapshot_conf.h | 7 - src/conf/virdomainmomentobjlist.h | 5 +- src/conf/virdomainsnapshotobjlist.h | 13 - src/datatypes.h | 33 +- src/driver-hypervisor.h | 87 ++- src/qemu/qemu_blockjob.h | 1 + docs/Makefile.am | 3 + docs/apibuild.py | 2 + docs/docs.html.in | 10 +- docs/domainstatecapture.html.in | 313 ++++++++ docs/format.html.in | 2 + docs/formatbackup.html.in | 181 +++++ docs/formatcheckpoint.html.in | 204 +++++ docs/formatsnapshot.html.in | 82 +- docs/index.html.in | 4 +- docs/schemas/domainbackup.rng | 219 ++++++ docs/schemas/domaincheckpoint.rng | 94 +++ examples/object-events/event-test.c | 3 + libvirt.spec.in | 3 + mingw-libvirt.spec.in | 6 + po/POTFILES | 1 + src/Makefile.am | 2 + src/conf/domain_conf.c | 2 +- src/conf/snapshot_conf.c | 2 +- src/conf/virdomainsnapshotobjlist.c | 166 ---- src/datatypes.c | 63 +- src/libvirt-domain-checkpoint.c | 749 +++++++++++++++++++ src/libvirt-domain-snapshot.c | 311 ++++---- src/libvirt-domain.c | 289 ++++++- src/libvirt_private.syms | 4 +- src/libvirt_public.syms | 21 + tests/Makefile.am | 4 + tests/domainbackupxml2xmlin/backup-pull.xml | 9 + tests/domainbackupxml2xmlin/backup-push.xml | 9 + tests/domainbackupxml2xmlin/empty.xml | 1 + tests/domainbackupxml2xmlout/backup-pull.xml | 9 + tests/domainbackupxml2xmlout/backup-push.xml | 9 + tests/domainbackupxml2xmlout/empty.xml | 7 + tests/domaincheckpointxml2xmlin/empty.xml | 1 + tests/domaincheckpointxml2xmlin/sample.xml | 7 + tests/domaincheckpointxml2xmlout/empty.xml | 10 + tests/domaincheckpointxml2xmlout/sample.xml | 16 + tests/virschematest.c | 4 + tools/virsh-domain.c | 8 +- 50 files changed, 2794 insertions(+), 431 deletions(-) create mode 100644 include/libvirt/libvirt-domain-checkpoint.h create mode 100644 docs/domainstatecapture.html.in create mode 100644 docs/formatbackup.html.in create mode 100644 docs/formatcheckpoint.html.in create mode 100644 docs/schemas/domainbackup.rng create mode 100644 docs/schemas/domaincheckpoint.rng create mode 100644 src/libvirt-domain-checkpoint.c create mode 100644 tests/domainbackupxml2xmlin/backup-pull.xml create mode 100644 tests/domainbackupxml2xmlin/backup-push.xml create mode 100644 tests/domainbackupxml2xmlin/empty.xml create mode 100644 tests/domainbackupxml2xmlout/backup-pull.xml create mode 100644 tests/domainbackupxml2xmlout/backup-push.xml create mode 100644 tests/domainbackupxml2xmlout/empty.xml create mode 100644 tests/domaincheckpointxml2xmlin/empty.xml create mode 100644 tests/domaincheckpointxml2xmlin/sample.xml create mode 100644 tests/domaincheckpointxml2xmlout/empty.xml create mode 100644 tests/domaincheckpointxml2xmlout/sample.xml -- 2.20.1

[libvirt] [dockerfiles PATCH] Add Dockerfile for i686 cross-compilation
by Andrea Bolognani 27 Mar '19

27 Mar '19

We didn't add this until now because i686 cross-compilation requires special care and lcitool was known to produce broken Dockerfiles, but that's been fixed as of libvirt-jenkins-ci commit f72d09153905 so we can finally go ahead and complete our coverage of non-x86_64 architectures.

[libvirt] [PATCH] spec: Move ldconfig calls from -client to -libs
by Andrea Bolognani 27 Mar '19

27 Mar '19

ldconfig needs to be called after installing or uninstalling shared libraries. For a very long time, libvirt didn't have a separate package containing just the shared libraries, and so it shipped them in the same one as the clients. Since commit 70b4f0e719cd, however, shared libraries have been moved from -client to their own -libs package; unfortunately, the corresponding ldconfig calls were not moved at the same time, which is what this commit takes care of.

[libvirt] [PATCH v5 00/20] Incremental Backup API additions
by Eric Blake 26 Mar '19

26 Mar '19

The following is the latest version of my API proposal for incremental backups, and follows along from the demo I presented as part of my KVM Forum 2018 talk: https://kvmforum2018.sched.com/event/FzuB/facilitating-incremental-backup-e… The patches are also available via https://repo.or.cz/libvirt/ericb.git at the tag backup-v5. Depends on my earlier bulk redefine for snapshots, which is pending review at v3: https://www.redhat.com/archives/libvir-list/2019-March/msg00144.html I haven't finished addressing all of John Ferlan's review comments from v4 (including the fact that several of these larger patches need to be split for easier reviews, and the fact that I want virDomainSnapshotObj and virDomainCheckpointObj to share a common base class); but I'm posting this now because I _have_ completed: - push mode backups mostly work (event notification is still not polished, but the fact that I can now do both push and pull modes is nice) - bulk mode list/redefine, accessible via 'virsh dumpxml --checkpoints' and 'virsh snapshot-create --redefine-list' - move virDomainBackup() into libvirt-domain.h (libvirt-domain-checkpoint.h is now JUST about standalone checkpoint objects; then both virDomainBackup() and virDomainSnapshotCreateXML() will be able to create a checkpoint in parallel) - rebase to master (5.2 now instead of 5.1, start using VIR_AUTOFREE in more places, ...) I'm still debating about making <domaincheckpoint> a sub-element of <domainbackup> (in which case I can reuse virDomainSnapshotCreateXML() to create a backup) or keeping it as a separate XML argument (in which case I need to add an API for virDomainSnapshotCreateXMLWithSnapshot()). I also need to work out an API for listing all currently running jobs (even if the current backup code can only run one job at a time, we know we want support in the future for parallel backup jobs). So there WILL be a v6. Hopefully, though, we can start trimming off the front of the series, and at least now the tail of the series currently compiles (John gave up review on v4 when he ran into rebase issues - although with our current rate of VIR_AUTOFREE conversions, there may again be rebase issues soon...) since v4: 001/20:[----] [-C] 'domain_conf: Expose virDomainStorageNetworkParseHost' 002/20:[down] 'qemu:

[libvirt] [PATCH v2 00/14] qemu_hotplug: refactor device detach functions to fix one serious and other minor bugs
by Laine Stump 26 Mar '19

26 Mar '19

V1: https://www.redhat.com/archives/libvir-list/2019-March/msg01455.html I pushed patches 01-12, since they were acked, and pushing them leaves the code in no worse state than it was before (all tests still pass). There are 4 new patches in V2, created as a result of Peter asking for patches to be split, or for further refactoring. Still to be done: Peter pointed out that qemuDomainUpdateDeviceLlist() really shouldn't be called until after qemu has sent the DEVICE_DELETED event. That is on my list of followups, but the patches here are still a valid improvement even without that (After his comment, I noticed that we are also calling virDomainSaveStatus too soon - it also shouldn't be called until after DEVICE_DELETED).
