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. It does not change the behavior if the cpu bandwidth for hypervisor
is unlimited.
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
