v8: two new bug cleanup commits, move major()/minor() handling out of domain_conf.c into cgroup.c, and fix behavior when more than one device is listed, add a test for xml parsing. v7 was here (1-3 are already applied, 4-5 of that series are now 3-4): https://www.redhat.com/archives/libvir-list/2011-November/msg00317.html Eric Blake (2): API: prevent query of --live and --config at once qemu: fix blkiotune --live --config Hu Tao (2): blkiotune: add interface for blkiotune.device_weight blkiotune: add qemu support for blkiotune.device_weight docs/formatdomain.html.in | 29 +++- docs/schemas/domaincommon.rng | 26 ++- include/libvirt/libvirt.h.in | 10 + src/conf/domain_conf.c | 99 +++++++++- src/conf/domain_conf.h | 14 ++ src/libvirt.c | 36 +++- src/libvirt_private.syms | 2 + src/qemu/qemu_cgroup.c | 20 ++ src/qemu/qemu_driver.c | 223 +++++++++++++++++++- src/util/cgroup.c | 51 +++++ src/util/cgroup.h | 4 + .../qemuxml2argv-blkiotune-device.args | 4 + .../qemuxml2argv-blkiotune-device.xml | 36 +++ tests/qemuxml2argvtest.c | 1 + tests/qemuxml2xmltest.c | 1 + tools/virsh.c | 43 +++- tools/virsh.pod | 8 +- 17 files changed, 576 insertions(+), 31 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-blkiotune-device.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-blkiotune-device.xml -- 1.7.7.1
