+Important: The openrc libvirtd init script is now broken up into two
+separate services: libvirtd, that solely handles the daemon, and
+libvirt-guests, that takes care of clients during shutdown/restart of the
+host. In order to reenable client handling, edit /etc/conf.d/libvirt-guests
+and enable the service and start it:
+
+	$ rc-update add libvirt-guests
+	$ service libvirt-guests start
+
+
+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. It
+will pull in required runtime dependencies
+
+
+If you are using dnsmasq on your system, you will have to configure
+/etc/dnsmasq.conf to enable the following settings:
+
+	bind-interfaces
+	interface or except-interface
+
+Otherwise you might have issues with your existing DNS server.
+
+
+For openrc users:
+
+	Please use /etc/conf.d/libvirtd to control the '--listen' parameter for
+	libvirtd.
+
+	Use /etc/init.d/libvirt-guests to manage clients on restart/shutdown of
+	the host. The default configuration will suspend and resume running kvm
+	guests with 'managedsave'. This behavior can be changed under
+	/etc/conf.d/libvirt-guests
+
+
+If you have built libvirt with policykit support, a new group "libvirt" has
+been created. Simply add a user to the libvirt group in order to grant
+administrative access to libvirtd. Alternatively, drop a custom policykit
+rule into /etc/polkit-1/rules.d.
+
+If you have built libvirt without policykit support (USE=-policykit), you
+must change the unix sock group and/or perms in /etc/libvirt/libvirtd.conf
+in order to allow normal users to connect to libvirtd.
+
+
+If libvirt is built with USE=caps, libvirt will now start qemu/kvm VMs
+with non-root privileges. Ensure any resources your VMs use are accessible
+by qemu:qemu.
