B<cpu> (sort by %CPU used),
-B<mem> (sort by memory used),
+B<mem> (sort by total memory),
B<time> (sort by total time),
B<id> (sort by domain ID),
B<name> (sort by domain name),

Note that in the current implementation, options specified in
the init file override options specified on the command line.
This is a bug and this behaviour may change in the future.
+=head1 NOTES

+=head2 NETWORK RX BYTES AND PACKETS
+
+Libvirt/virt-top has no way to know that a packet transmitted to a
+guest was received (eg. if the guest is not listening). In the
+network RX stats, virt-top reports the packets transmitted to the
+guest, on the basis that the guest might receive them.
+
+In particular this includes broadcast packets. Because of the way
+that Linux bridges work, if the guest is connected to a bridge, it
+will probably see a steady "background noise" of RX packets even when
+the network interface is idle or down. These are caused by STP
+packets generated by the bridge.

=item 3. Get version of virt-top and version of libvirt.
-In virt-top, press the I<h> (help) key, and write down the version of
-virt-top and the version of libvirt. They are shown in the first
-line.
+Use:
+
+ virt-top --version
+
+If you can get the precise version of libvirt you are using
+then that too is helpful.
