[libvirt] [PATCH v1 00/11] Allow minimal bandwidth guarantee

This is a rework of my one year old patchset [1]. If you are brave enough and start reviewing it, you may want to read the last patch first. The whole magic hidden behind the scene is documented there. For now, the only supported combination where this works is virtual interface connected to virtual network. This network MUST have an inbound average set, at least. This tells how much bandwidth do we have, and how much can we guarantee. If we would miss this info, then we cannot guarantee anything. On the other hand, this is just a very small part of whole problem. Users MUST configure all other devices on traffic path to follow up their setting in libvirt. But that's out of our scope. 1: http://www.redhat.com/archives/libvir-list/2011-December/msg00486.html Michal Privoznik (11): bandwidth: add new 'floor' attribute bandwidth: Create hierarchical shaping classes bandwidth: Create (un)plug functions bandwidth: Create rate update function bandwidth: Create network (un)plug functions network: Create real network status files domain: Keep assigned class_id in domstatus XML network: Update status file on (un)plug network: Allow class ID to be reused bandwidth: Attach sfq to leaf node bandwidth: Add documentation docs/formatdomain.html.in | 20 ++- docs/schemas/networkcommon.rng | 5 + po/POTFILES.in | 1 + src/Makefile.am | 7 +- src/conf/domain_conf.c | 10 +- src/conf/domain_conf.h | 1 + src/conf/netdev_bandwidth_conf.c | 54 ++++++- src/conf/netdev_bandwidth_conf.h | 3 +- src/conf/network_conf.c | 230 ++++++++++++++++++++++----- src/conf/network_conf.h | 6 + src/libvirt_network.syms | 8 + src/libvirt_private.syms | 1 + src/lxc/lxc_process.c | 3 +- src/network/bridge_driver.c | 224 +++++++++++++++++++++++++- src/network/bridge_driver.h | 10 +- src/qemu/qemu_command.c | 35 +++-- src/qemu/qemu_domain.c | 66 +++++++- src/qemu/qemu_driver.c | 2 +- src/qemu/qemu_process.c | 12 ++ src/util/virnetdevbandwidth.c | 326 +++++++++++++++++++++++++++++++++++++- src/util/virnetdevbandwidth.h | 25 +++- src/util/virnetdevmacvlan.c | 2 +- 22 files changed, 956 insertions(+), 95 deletions(-) create mode 100644 src/libvirt_network.syms -- 1.7.8.6
