TODO:
1. We create sub directory for each vcpu in cpu subsystem. So
we should recalculate cpu.shares for each vcpu.
Changelog:
v3: fix some small bugs
implement the simple way
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 (6):
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
qemu: Implement cfs_period and cfs_quota's modification
