[libvirt] [PATCHv2 0/9] support to set cpu bandwidth for hypervisor threads

Currently, we only can set cpu bandwidth for vcpu. If the hypervisor threads consume too much cpu time, it may affect the vcpu. This patchset allows the user to control the cpu bandwidth for hypervisor threads. Changes: v2: - rename qemuSetupCgroupVcpuBW to qemuSetupCgroupCpuBandwidth - limit cpu bandwidth only for vcpus - update doc about hypervisor_period/hypervisor_quota - add virCgroupMoveTask to libvirt_private.syms Hu Tao (3): rename qemuSetupCgroupVcpuBW to qemuSetupCgroupCpuBandwidth limit cpu bandwidth only for vcpus update doc about hypervisor_period/hypervisor_quota Wen Congyang (6): Introduce the function virCgroupForHypervisor introduce the function virCgroupMoveTask() create a new cgroup and move all hypervisor threads to the new cgroup Update XML Schema for new entries qemu: Implement hypervisor's period and quota tunable XML configuration and parsing qemu: Implement hypervisor_period and hypervisor_quota's modification docs/schemas/domaincommon.rng | 10 ++ include/libvirt/libvirt.h.in | 16 ++++ src/conf/domain_conf.c | 25 +++++- src/conf/domain_conf.h | 2 + src/libvirt_private.syms | 2 + src/qemu/qemu_cgroup.c | 107 ++++++++++++++++------ src/qemu/qemu_cgroup.h | 8 +- src/qemu/qemu_driver.c | 201 +++++++++++++++++++++++++++-------------- src/qemu/qemu_process.c | 4 + src/util/cgroup.c | 96 ++++++++++++++++++++ src/util/cgroup.h | 6 ++ tools/virsh.pod | 11 ++- 12 files changed, 381 insertions(+), 107 deletions(-) -- 1.7.4.4
