[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

The QEMU driver is what we call a 'stateful' driver, which means it only lives within the libvirtd daemon, and applications communicate with the QEMU driver indirectly via the 'remote' driver. 'remote' was probably a bad name for this driver - its really just doing local RPC calls over a UNIX domain socket and is very fast. So the behaviour you see is totally expected & nothing to worry about.
