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.
