One annoyance I had with the defaults are the short dhcp lease time configured for dnsmasq, causing repeated dhcp lease logging in the logs. Turns out you can configure the lease time using virsh net-edit. The libvrit docs contain additional useful configuration options. Another small thing but big quality of life improvement is exporting LIBVIRT_DEFAULT_URI='qemu:///system', so that everything you execute uses the correct connection.
