[libvirt] remote driver?

Hi, I am connecting to libvirtd with virsh using qemu:///system connection type. However, it seems virsh uses "remote" driver for all the action on the VM. So this means qemu:///system considers all the action is done "remotely" even if it is on the same physical machine? I really expected that it uses "QEMU" driver, but that is not the case. So I wonder in which case "QEMU" driver is used? Many thanks, Jun
