Hi all, is it possible to monitor guest's interface's stat which uses SR-IOV virtual function?

I don't know how qemu/libvirt implement monitoring, if functions like interfaceStats are implemented in the host, I think there's little chance to do this due to SR-IOV's nature, is it right?

If i can't use libvirt to monitor SR-IOV interfaces, is there another way to do monitoring except putting agent in the guest OS?
