Limit the CPU usage of KVM

Hi KVM experts, Our user case needs to run KVM and application on host together. To reserve some CPU resource for application, we want to limit the CPU usage of KVM. Without KVM CPU usage limitation, the idle CPU of host OS becomes 0% in peak time. I have searched this topic on internet, but
