So, if we donot limit the hypervisor, the behavior shoule not be changed. So we should limit the whole vm. If the hypervisor threads are limited, there is no need to limit the whole vm.
need to tune hypervisor quota to limit vcpu-only quota ? Sounds strange to me.
No, current implemetion is: 1. limit vcpu and hypervisor: vm is not limited 2. limit vcpu only: vm is limited 3. limit hypervisor: vm is not limited 4. vcpu and hypervisor are not limited: vm is not limited.
In 2. vm ----- quota_is_limited |- hypervisor ----- quota is unlimited |- vcpu[0...x] ----- quota is limited Hm...vm is limited. It seems user need to tune vm's quota...can user makes vm's quota to be unlimited and limit *only* vpcus as Xen ? Thanks, -Kame
