The libvirtd config defaults to TLS, so you need to explicitly
turn that off by editing /etc/libvirt/libvirtd.conf and set
listen_tls=0 and listen_tcp=1

Even though you "trust" your network, I'd still advise doing
some level of auth. If you configure SASL with TCP, and use
the Digest-MD5 protocol for SASL you'll get reasonably
strong password auth + channel encryption.
