TODO:
1. We create sub directory for each vcpu in cpu subsystem. So
we should recalculate cpu.shares for each vcpu.
Changelog:
v2: almost rewrite the patchset to support to control each vcpu's
bandwidth.
Limit quota to [-1, 2^64/1000] at the schemas level. We will
check it at cgroup level.
Wen Congyang (10):
Introduce the function virCgroupForVcpu
cgroup: Implement cpu.cfs_period_us and cpu.cfs_quota_us tuning API
Update XML Schema for new entries
qemu: Implement period and quota tunable XML configuration and
parsing.
support to pass VIR_DOMAIN_AFFECT_CURRENT to virDomainGetVcpusFlags()
vcpubandwidth: introduce two new libvirt APIs
vcpubandwidth: implement the code to support new API for the qemu
driver
vcpubandwidth: implement the remote protocol to address the new API
vcpubandwidth: Implement virsh support
doc: Add documentation for new cputune elements period and quota
