Re: [libvirt] [RFC][PATCHv1 2/5] libvirt - new API for getting percpu statistics of VM

Per (host) cpu activity of VMs are very insterested numbers when running VMs on large SMPs. virt-top -1 mode tries to provide the information. (But it's not implemented.) This patch adds a libvirt interface to get per cpu statistics of each nodes. This patch just adds an interface and driver entry points. So,  - doesn't include patches for python.  - doesn't include any driver. Following patches will add some drivers and codes for python.
