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 diff to v1: -Laine's suggestions worked in diff to v2: -again Laine's suggestions worked in (drop libvirt_network.syms, don't check for floor twice, etc.) Michal Privoznik (8): bandwidth: Attach sfq to leaf node bandwidth: add new 'floor' attribute bandwidth: Create hierarchical shaping classes bandwidth: Create (un)plug functions bandwidth: Create rate update function bandwidth: Create network bandwidth (un)plug functions network: Create real network status files domain: Keep assigned class_id in domstatus XML docs/formatdomain.html.in | 23 +++- docs/schemas/networkcommon.rng | 5 + po/POTFILES.in | 1 + src/conf/domain_conf.c | 19 ++- src/conf/domain_conf.h | 1 + src/conf/netdev_bandwidth_conf.c | 67 +++++++-- src/conf/netdev_bandwidth_conf.h | 3 +- src/conf/network_conf.c | 229 +++++++++++++++++++++----- src/conf/network_conf.h | 6 + src/libvirt_private.syms | 4 + src/lxc/lxc_process.c | 3 +- src/network/bridge_driver.c | 242 +++++++++++++++++++++++++++- src/qemu/qemu_command.c | 3 +- src/qemu/qemu_driver.c | 2 +- src/util/virnetdevbandwidth.c | 331 +++++++++++++++++++++++++++++++++++++- src/util/virnetdevbandwidth.h | 25 +++- src/util/virnetdevmacvlan.c | 2 +- 17 files changed, 886 insertions(+), 80 deletions(-) -- 1.7.8.6 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
