Doing an out-of-the-box build on RHEL 5 is the oldest configuration still actively (if marginally) supported, ideally for as long as RHEL 5 remains a live platform (several more years to go). We have build-bots that ensure that we can build on RHEL 5, although I'm not sure if those buildbots are exercising 'make rpm' to test the older parts of the spec file. Historically, RHEL 5.10 is based off of libvirt-0.8.2, and that was the release in use during Fedora 13. So it's _definitely_ worth culling any conditionals older than F13; but stuff between F13 and F18 might be shared with RHEL 5, and therefore more effort to cull the Fedora side while still leaving the RHEL side intact. I could go either way if we were to set some sort of policy (maybe: any fedora release that is unsupported for more than a year is no longer required to be supported in the spec file), and use that to justify cleanups of older parts of the spec file as long as it doesn't break RHEL 5. F16 is definitely more than a year out-of-date, F18 is a bit more borderline on whether we are ready to call it unsupported. Anyone else on the libvirt list have an opinion on how far back we can clean without annoying people that are slow on the upgrade to modern Fedora? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

[libvirt] [PATCH 0/2] Implement interface stats for BSD
by Roman Bogorodskiy 16 Jul '14

16 Jul '14

This series implements support for querying network interface stats on (Free)BSD. It's more of an RFC, because I'm uncertain about few things: - It feels a little strange to have a source file that implements only a single function like this. I am wondering if it would be better to just move it to something like util/virnetdev.c? - FreeBSD stores interface data in the if_data struct and a number of outgoing packet drops is stored in a field 'ifi_oqdrops'. This field was added in -CURRENT and later merged back to 10-STABLE. In order not to break the ABI, it's available only if _IFI_OQDROPS is defined. I've added a configure.ac check which adds -D_IFI_OQDROPS before checking this field and resetting it back if it is not present. This way, this flag will present when the field is available even if the flag is not needed (e.g. on -CURRENT). Is there a better way of doing it? I was thinking about trying to check this field without the flag and if it fails check one more time with the flag, but it looks a little messy. - Did I get it right that the stats reported are from the guest POV, e.g. when downloading a large file from guest, it should look like: vnet0 rx_bytes 731603341 vnet0 rx_packets 518354 vnet0 rx_errs 0 vnet0 rx_drop 0 vnet0 tx_bytes 17577834 vnet0 tx_packets 264226 vnet0 tx_errs 0 vnet0 tx_drop 0 Roman Bogorodskiy (2): util: virstatslinux: make more generic Implement interface stats for BSD configure.ac | 13 ++++- po/POTFILES.in | 2 +- src/Makefile.am | 2 +- src/libvirt_linux.syms | 3 -- src/libvirt_private.syms | 2 + src/lxc/lxc_driver.c | 2 +- src/openvz/openvz_driver.c | 2 +- src/qemu/qemu_driver.c | 16 +----- src/uml/uml_driver.c | 2 +- src/util/{virstatslinux.c => virstats.c} | 93 +++++++++++++++++++++++++------- src/util/{virstatslinux.h => virstats.h} | 12 ++--- src/xen/xen_hypervisor.c | 2 +- tests/statstest.c | 2 +- 13 files changed, 102 insertions(+), 51 deletions(-) rename src/util/{virstatslinux.c => virstats.c} (61%) rename src/util/{virstatslinux.h => virstats.h} (77%) -- 1.9.0

[libvirt] [PATCH v2 00/16] Support for per-guest-node binding
by Martin Kletzander 16 Jul '14

16 Jul '14

Currently we are only able to bind the whole domain to some host nodes using the /domain/numatune/memory element. Numerous requests were made to support host<->guest numa node bindings, so this series tries to implement that using /domain/numatune/memnode elements. That is incompatible with automatic numa placement (numad) since that makes no sense. Some of these patches were ACK'd in the previous round, but this version completely rewrites the parsing and formatting of the numatune XML element and places it into a separate file. Hence the repost of all the patches even with those ACK'd ones. Patches 1-3 move some code around, patch 4 adds cell id specification into the XML (which is used later on). Then patches 5-7 rework the numatune handling, which clears out some odd things, but mostly cleans the parsing code. Patch 8 adds the support for memnode elements in the XML conf code and together with patch 9 enables the use of it outside numatune_conf.c. After that, I needed to probe qemu for 2 capabilities; for one of them patch 10 adds the possibility to probe for it, then two following patches 11 and 12 add the probing data. One of the capabilities tells us that we can use disjoint ranges (not necessarily for the cpus= param) with qemu, so patch 13 makes a use of it. Finally patch 14 uses the memnode data to tell qemu which host nodes should be used for the allocations of memory blocks. Patch 15 does almost nothing, but the next patch looks better with it. And the last patch, number 16, fixes a bug with KVM and cgroups. One last note, APIs for handling the memnode settings will be added later. I'm sending this to prepare the ground for Michal's work with hugepages. Martin Kletzander (16): qemu: purely a code movement qemu: remove useless error check conf: purely a code movement conf, schema: add 'id' field for cells numatune: create new module for numatune numatune: unify numatune struct and enum names numatune: Encapsulate numatune configuration in order to unify results conf, schema: add support for memnode elements numatune: add support for per-node memory bindings in private APIs qemu: allow qmp probing for cmdline options without params qemu: memory-backend-ram capability probing qemu: newer -numa parameter capability probing qemu: enable disjoint numa cpu ranges qemu: pass numa node binding preferences to qemu qemu: split out cpuset.mems setting qemu: leave restricting cpuset.mems after initialization docs/formatdomain.html.in | 26 +- docs/schemas/domaincommon.rng | 22 + po/POTFILES.in | 1 + src/Makefile.am | 3 +- src/conf/cpu_conf.c | 39 +- src/conf/cpu_conf.h | 3 +- src/conf/domain_conf.c | 203 ++----- src/conf/domain_conf.h | 10 +- src/conf/numatune_conf.c | 589 +++++++++++++++++++++ src/conf/numatune_conf.h | 108 ++++ src/libvirt_private.syms | 24 +- src/lxc/lxc_cgroup.c | 20 +- src/lxc/lxc_controller.c | 5 +- src/lxc/lxc_native.c | 15 +- src/parallels/parallels_driver.c | 7 +- src/qemu/qemu_capabilities.c | 16 +- src/qemu/qemu_capabilities.h | 2 + src/qemu/qemu_cgroup.c | 52 +- src/qemu/qemu_cgroup.h | 4 +- src/qemu/qemu_command.c | 98 +++- src/qemu/qemu_driver.c | 84 ++- src/qemu/qemu_monitor.c | 6 +- src/qemu/qemu_monitor.h | 3 +- src/qemu/qemu_monitor_json.c | 8 +- src/qemu/qemu_monitor_json.h | 3 +- src/qemu/qemu_process.c | 12 +- src/util/virnuma.c | 61 +-- src/util/virnuma.h | 28 +- tests/qemucapabilitiesdata/caps_1.6.50-1.caps | 1 + tests/qemucapabilitiesdata/caps_1.6.50-1.replies | 5 + tests/qemumonitorjsontest.c | 20 +- .../qemuxml2argv-cpu-numa-disjoint.args | 6 + .../qemuxml2argv-cpu-numa-disjoint.xml | 28 + tests/qemuxml2argvdata/qemuxml2argv-cpu-numa1.xml | 6 +- tests/qemuxml2argvdata/qemuxml2argv-cpu-numa2.xml | 6 +- tests/qemuxml2argvdata/qemuxml2argv-cpu-numa3.xml | 25 + .../qemuxml2argv-numatune-auto-prefer.xml | 29 + .../qemuxml2argv-numatune-memnode-no-memory.args | 8 + .../qemuxml2argv-numatune-memnode-no-memory.xml | 30 ++ .../qemuxml2argv-numatune-memnode-nocpu.xml | 25 + .../qemuxml2argv-numatune-memnode.args | 11 + .../qemuxml2argv-numatune-memnode.xml | 33 ++ .../qemuxml2argv-numatune-memnodes-problematic.xml | 31 ++ tests/qemuxml2argvtest.c | 12 + .../qemuxml2xmlout-cpu-numa1.xml | 28 + .../qemuxml2xmlout-cpu-numa2.xml | 28 + .../qemuxml2xmlout-numatune-auto-prefer.xml | 29 + .../qemuxml2xmlout-numatune-memnode.xml | 33 ++ tests/qemuxml2xmltest.c | 8 + 49 files changed, 1467 insertions(+), 387 deletions(-) create mode 100644 src/conf/numatune_conf.c create mode 100644 src/conf/numatune_conf.h create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-cpu-numa-disjoint.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-cpu-numa-disjoint.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-cpu-numa3.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-numatune-auto-prefer.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode-no-memory.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode-no-memory.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode-nocpu.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-numatune-memnodes-problematic.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-cpu-numa1.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-cpu-numa2.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-numatune-auto-prefer.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-numatune-memnode.xml -- 2.0.0
