I intentionally set things up so 'virsh help interface' lists
commands in alphabetical order, but 'man virsh' lists them in
topical order; this matches our practice on some other commands.
* tools/virsh.pod: Document all iface commands.
* tools/virsh.c (ifaceCmds): Sort.

Dan was partially right:
> Though we will be wanting a followup patch for virsh.pod to add docs
> for this
but missed the fact that _none_ of the iface-* commands were
documented, so Laine's initial patch wasn't making the situation
any worse. At any rate, this patch was heavily copy-and-pasted
from existing net-* commands.

+=head1 INTERFACE COMMANDS
+
+The following commands manipulate host interfaces to be used by
+virtual networks. A lot of the commands for host interfaces are
+similar to the ones used for domains, and the way to name an interface
+is either by its name or its MAC address.
+
+=over 4
+
+=item B<iface-define> I<file>
+
+Define a host interface from an XML I<file>, the interface is just defined but
+not started.
+
+=item B<iface-destroy> I<interface>
+
+Destroy a given host interface, such as by running "if-down" to
+disable that interface from active use. This takes effect immediately.
+
+=item B<iface-dumpxml> I<interface> optional I<--inactive>
+
+Output the host interface information as an XML dump to stdout. If
+I<--inactive> is specified, then the output reflects the persistent
+state of the interface that will be used the next time it is started.
+
+=item B<iface-edit> I<interface>
+
+Edit the XML configuration file for a host interface.
+
+This is equivalent to:
+
+ virsh iface-dumpxml iface > iface.xml
+ vi iface.xml (or make changes with your other text editor)
+ virsh iface-define iface.xml
+
+except that it does some error checking.
+
+The editor used can be supplied by the C<$VISUAL> or C<$EDITOR> environment
+variables, and defaults to C<vi>.
+
+=item B<iface-list> optional I<--inactive> or I<--all>
+
+Returns the list of active host interfaces. If I<--all> is specified
+this will also include defined but inactive interfaces. If
+I<--inactive> is specified only the inactive ones will be listed.
+
+=item B<iface-name> I<iface-MAC>
+
+Convert a host interface MAC to interface name.
+
+=item B<iface-name> I<iface-MAC>
+
+Convert a host interface name to MAC address.
+
+=item B<iface-start> I<iface>
+
+Start a (previously defined) host interface.
+
+=item B<iface-undefine> I<iface>
+
+Undefine the configuration for an inactive host interface.
+
+=item B<iface-begin>
+
+Create a snapshot of current host interface settings, which can later
+be committed (I<iface-commit>) or restored (I<iface-rollback>). If a
+snapshot already exists, then this command will fail until the
+previous snapshot has been committed or restored. Undefined behavior
+results if any external changes are made to host interfaces outside of
+the libvirt API between the beginning of a snapshot and its eventual
+commit or rollback.
+
+=item B<iface-commit>
+
+Confirm that all changes since the last I<iface-begin> are working,
+and delete the rollback point. If no interface snapshot has already
+been started, then this command will fail.
+
+=item B<iface-rollback>
+
+Revert all host interface settings back to the state recorded in the
+last I<iface-begin>. If no interface snapshot has already been
+started, then this command will fail. If appropriate netcf init
+scripts are also installed, then rebooting the host may serve as an
+implicit rollback point.
