Re: [libvirt] [PATCH v4 0/7] Add support for setting QoS

This patch series add support for setting traffic shaping and policing on both domain's interface and network's virtual bridge. Basically, this is done via 'tc' from iproute2 package. For shaping is HTB used, for policing we need u32 match selector. Both should be available in RHEL-6 kernel. How this works: On an virtual interface which has limits defined a root qdisc are replaced. Ingress root for outbound traffic shaping and egress for inbound. Basically, in inbound traffic policing is applied, on outbound shaping. New qdiscs are set to limit the traffic to rate set in XML. For shaping it is possible to set the size of buffer. Accepted values for rate, peak and burst are integer numbers. Units are kilobytes per second for rate or kilobytes for size. Supported devices are VIR_DOMAIN_NET_TYPE_NETWORK, VIR_DOMAIN_NET_TYPE_BRIDGE and VIR_DOMAIN_NET_TYPE_DIRECT. diff to v3: -Laine's review included diff to v2: -Jirka's review included diff to v1: -rebase to current HEAD -add support for macvtap devices Michal Privoznik (7): bandwidth: Define schema and create documentation bandwidth: Declare internal structures bandwidth: Add parsing and free functions bandwidth: Create format functions bandwidth: Implement functions to enable and disable QoS bandwidth: Add test cases for network bandwidth: Add domain schema test suite configure.ac | 4 + docs/formatdomain.html.in | 34 +++ docs/formatnetwork.html.in | 30 ++ docs/schemas/domain.rng | 3 + docs/schemas/network.rng | 3 + docs/schemas/networkcommon.rng | 48 +++ libvirt.spec.in | 2 +- src/conf/domain_conf.c | 8 + src/conf/domain_conf.h | 1 + src/conf/network_conf.c | 10 + src/conf/network_conf.h | 1 + src/libvirt_private.syms | 5 + src/network/bridge_driver.c | 18 ++ src/qemu/qemu_command.c | 11 +- src/util/macvtap.c | 12 +- src/util/macvtap.h | 3 +- src/util/network.c | 380 +++++++++++++++++++++++++ src/util/network.h | 22 ++ tests/domainschemadata/domain-bandwidth.xml | 72 +++++ tests/networkxml2xmlin/bandwidth-network.xml | 16 + tests/networkxml2xmlout/bandwidth-network.xml | 16 + tests/networkxml2xmltest.c | 1 + 22 files changed, 696 insertions(+), 4 deletions(-) create mode 100644 tests/domainschemadata/domain-bandwidth.xml create mode 100644 tests/networkxml2xmlin/bandwidth-network.xml create mode 100644 tests/networkxml2xmlout/bandwidth-network.xml
