DOC_CONTENTS="For the basic networking support (bridged and routed networks)
you don't need any extra software. For more complex network modes
including but not limited to NATed network, you can enable the
'virt-network' USE flag.\n\n
If you are using dnsmasq on your system, you will have
to configure /etc/dnsmasq.conf to enable the following settings:\n\n
 bind-interfaces\n
 interface or except-interface\n\n
Otherwise you might have issues with your existing DNS server."
