[libvirt] [PATCH v6 00/23] network: refactor to decouple virt drivers from network driver
by Daniel P. Berrangé 18 Jun '19

18 Jun '19

An update to v1: https://www.redhat.com/archives/libvir-list/2018-December/msg00681.html v2: https://www.redhat.com/archives/libvir-list/2019-February/msg01581.html v3: https://www.redhat.com/archives/libvir-list/2019-March/msg01259.html v4: https://www.redhat.com/archives/libvir-list/2019-April/msg01186.html v5: https://www.redhat.com/archives/libvir-list/2019-May/msg00358.html Currently the network driver registers a set of callbacks with the virt driver in order to handle allocating/releasing network ports associated with guest NICs. This series introduces a virNetworkPortPtr object and associated XML that describes a network port. The virt drivers now call public APIs associated with this new object to create/delete ports for guest NICs. Changed in v6: - Fixed mistakes in RNG schema & example XML - Fix docs typos Changed in v5: - Separately track ports with type=network vs type=bridge to deal with fallout after reverting patches which merged them - Add RNG schema and XML format docs - Change to use classID attr on <bandwidth> isntead of of separate <class id="xx"/> element - Drop obsolete driver deps from RPM spec - Other misc bug fixes found during testing Changed in v4: - Merged the ACKd patches which didn't depend on other un-acked parts - Improve bandwidth error messages - Ensure we set floor sum to zero when starting network - Misc fixes for previous review comments NB, I have not added missing docs for the new XML doc format yet. This is work in progress. Changed in v3: - Remove unused API symbol - Fix dist of test data files Changed in v2: - Fix many bugs related to upgrades with running VMs - Convert over bandwidth controls to the new APIs - Handle reconnecting VIFs to bridges during startup - Much much more that I can't remember Daniel P. Berrangé (23): conf: allow bandwidth parsing / formatting to include class ID conf: introduce virNetworkPortDefPtr struct and XML support network: make networkLogAllocation independent of domain conf conf: add APIs to convert virDomainNetDef to virNetworkPortDef network: convert networkAllocateActualDevice to virNetworkPortDef network: convert networkNotifyActualDevice to virNetworkPortDef network: convert networkReleaseActualDevice to virNetworkPortDef network: convert hook script to take a network port XML network: remove the virDomainNetBandwidthChangeAllowed callback network: introduce networkAllocatePort network: introduce networkNotifyPort network: introduce networkReleasePort network: introduce networkUpdatePortBandwidth network: add public APIs for network port object access: add permissions for network port objects remote: add support for new network port APIs virsh: add support for network port APIs conf: support recording ports against virNetworkObjPtr network: add implementation of network port APIs lxc, libxl: notify network driver of NICs during reconnect lxc, libxl: save domain status after reconnect conf: record a portid against the domain conf conf: switch over to use network port APIs for virt drivers docs/docs.html.in | 1 + docs/formatdomain.html.in | 8 + docs/formatnetworkport.html.in | 212 +++ docs/hooks.html.in | 24 +- docs/schemas/domaincommon.rng | 5 + docs/schemas/networkcommon.rng | 5 + docs/schemas/networkport.rng | 154 +++ include/libvirt/libvirt-network.h | 122 ++ include/libvirt/virterror.h | 3 + libvirt.spec.in | 1 + src/access/genpolkit.pl | 2 +- src/access/viraccessdriver.h | 6 + src/access/viraccessdrivernop.c | 11 + src/access/viraccessdriverpolkit.c | 26 + src/access/viraccessdriverstack.c | 25 + src/access/viraccessmanager.c | 16 + src/access/viraccessmanager.h | 6 + src/access/viraccessperm.c | 6 + src/access/viraccessperm.h | 44 + src/conf/Makefile.inc.am | 2 + src/conf/domain_conf.c | 531 +++++++- src/conf/domain_conf.h | 49 +- src/conf/netdev_bandwidth_conf.c | 30 +- src/conf/netdev_bandwidth_conf.h | 2 + src/conf/network_conf.c | 8 +- src/conf/virnetworkobj.c | 303 +++++ src/conf/virnetworkobj.h | 34 + src/conf/virnetworkportdef.c | 508 +++++++ src/conf/virnetworkportdef.h | 113 ++ src/datatypes.c | 60 + src/datatypes.h | 41 + src/driver-network.h | 41 + src/libvirt-network.c | 444 +++++++ src/libvirt_private.syms | 23 +- src/libvirt_public.syms | 15 + src/libxl/libxl_driver.c | 33 + src/lxc/lxc_process.c | 35 + src/network/bridge_driver.c | 1182 ++++++++++------- src/qemu/qemu_driver.c | 8 +- src/remote/remote_daemon_dispatch.c | 73 + src/remote/remote_driver.c | 69 + src/remote/remote_protocol.x | 124 +- src/remote_protocol-structs | 69 + src/rpc/gendispatch.pl | 18 +- src/util/virerror.c | 9 + src/util/virhook.c | 4 +- src/util/virhook.h | 4 +- tests/Makefile.am | 7 + .../net-virtio-network-portgroup.xml | 6 +- tests/virnetdevbandwidthtest.c | 1 + .../plug-bridge-mactbl.xml | 9 + .../virnetworkportxml2xmldata/plug-bridge.xml | 15 + .../virnetworkportxml2xmldata/plug-direct.xml | 12 + .../plug-hostdev-pci.xml | 12 + .../plug-network.xml | 15 + tests/virnetworkportxml2xmldata/plug-none.xml | 8 + tests/virnetworkportxml2xmltest.c | 104 ++ tests/virschematest.c | 1 + tools/virsh-completer.c | 50 + tools/virsh-completer.h | 4 + tools/virsh-network.c | 399 +++++- tools/virsh-network.h | 5 + 62 files changed, 4499 insertions(+), 658 deletions(-) create mode 100644 docs/formatnetworkport.html.in create mode 100644 docs/schemas/networkport.rng create mode 100644 src/conf/virnetworkportdef.c create mode 100644 src/conf/virnetworkportdef.h create mode 100644 tests/virnetworkportxml2xmldata/plug-bridge-mactbl.xml create mode 100644 tests/virnetworkportxml2xmldata/plug-bridge.xml create mode 100644 tests/virnetworkportxml2xmldata/plug-direct.xml create mode 100644 tests/virnetworkportxml2xmldata/plug-hostdev-pci.xml create mode 100644 tests/virnetworkportxml2xmldata/plug-network.xml create mode 100644 tests/virnetworkportxml2xmldata/plug-none.xml create mode 100644 tests/virnetworkportxml2xmltest.c -- 2.21.0

[libvirt] [PATCH RFC 0/1] mdevctl: further config for vfio-ap
by Cornelia Huck 18 Jun '19

18 Jun '19

This patch adds a very rough implementation of additional config data for mdev devices. The idea is to make it possible to specify some type-specific key=value pairs in the config file for an mdev device. If a device is started automatically, the device is stopped and restarted after applying the config. The code has still some problems, like not doing a lot of error handling and being ugly in general; but most importantly, I can't really test it, as I don't have the needed hardware. Feedback welcome; would be good to know if the direction is sensible in general. Also available at https://github.com/cohuck/mdevctl conf-data Cornelia Huck (1): allow to specify additional config data mdevctl.libexec | 25 ++++++++++++++++++++++ mdevctl.sbin | 56 ++++++++++++++++++++++++++++++++++++++++++++++++- 2 files changed, 80 insertions(+), 1 deletion(-) -- 2.20.1

[libvirt] [PATCH 0/4] docs: Use CDNJS, update JavaScript libraries
by Andrea Bolognani 18 Jun '19

18 Jun '19

We're carrying around embedded copies of a few JavaScript libraries for use in our homepage, and we've been unforgivably bad at keeping them up to date. Instead of serving JavaScript from libvirt.org, use CDNJS so that users will get better performance and the load on our Web server will decrease (win-win!); at the same time, move from the positively ancient versions we're currently using to the freshest ones available.

[libvirt] [PATCH 0/5] docs: drvqemu: Clean up documentation regarding XML<->native conversion
by Peter Krempa 18 Jun '19

18 Jun '19

This is a follow up to the series for dropping qemu command line parsing. This fixes the qemu driver documentation. Note that the patches removing the outdated examples can be skipped if we wish to keep them around. I did not see a point in doing so though.

[libvirt] [PATCH v3] Produce more verbose error if cppi not found
by Michal Privoznik 18 Jun '19

18 Jun '19

It's fairly easy (especially for new contributors) to not spot the 'cppi not installed' line in the syntax-check output. Turn it into a banner that is more visible and at the same time add it as a build dependency. Unfortunately, RHEL doesn't ship cppi so we can add the dependency only for Fedora. Since it's v1 this has effectively became code copied over from Andrea's review suggestions.
