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. -- Emerging Technologies, Red Hat - http://et.redhat.com/~rjones/ Registered Address: Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 1TE, United Kingdom.
