docs: document iface-* commands
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.

=head1 INTERFACE COMMANDS
|
||||||
|
|
||||||
|
The following commands manipulate host interfaces. Often, these host
|
||||||
|
interfaces can then be used by name within domain <interface> elements
|
||||||
|
(such as a system-created bridge interface), but there is no
|
||||||
|
requirement that host interfaces be tied to any particular guest
|
||||||
|
configuration XML at all.
|
||||||
|
|
||||||
|
Many 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. However, using a MAC address for an I<iface>
|
||||||
|
argument only works when that address is unique (if an interface and a
|
||||||
|
bridge share the same MAC address, which is often the case, then using
|
||||||
|
that MAC address results in an error due to ambiguity, and you must
|
||||||
|
resort to a name instead).
|
||||||
|
|
||||||
|
=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, if the I<iface-MAC> is
|
||||||
|
unique among the host's interfaces.
|
||||||
|
|
||||||
|
=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, such as by running "if-up".
|
||||||
|
|
||||||
|
=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>
|
||||||
|
|
||||||
|
Declare all changes since the last I<iface-begin> as 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. Rebooting the host also serves
|
||||||
|
as an implicit rollback point.
