From: Hyman Huang <yong.hu...@smartx.com>
This patchset is the prerequisite for the vCPU dirty-limit feature:
https://patchew.org/Libvirt/cover.1703135535.git.yong.hu...@smartx.com/
As suggested by Daniel:
We've generally tried to avoid adding single purpose APIs for
tunable parameters, instead using APIs with virTypedParameter
arrays to allow bulk updates.
I note that we don't appear to have any mechanism currently
to set the VCPU scheduler tunables either
Perhaps we should have a more general
virDomainSetVCPUTuneParameters(virDomainPtr domain,
int vcpu,
virTypedParameterPtr params,
unsigned int params,
unsigned int flags);
Refer the following link to see more details:

We present the qemuDomainSetVcpuTuneParameters API separately
because the patchset is somewhat self-contained.
Please review,
Yong
