For reasons of history the qemu driver contains the network driver.
When libvirt connects to the hypervisor it actually makes two
connections -- one (which may be local, not an actual socket) to the
hypervisor you requested, and another (usually over a Unix socket) to
libvirtd for virNetwork* operations.
The network connection is entirely optional[1], which is why you get
the error above but your connection succeeds.
Rich.
[1] Optional unless you want to make virNetwork* calls of course.
