}


=item my $uuid = $net->get_uuid()

Returns a 16 byte long string containing the raw globally unique identifier
(UUID) for the network.

=item my $uuid = $net->get_uuid_string()

Returns a printable string representation of the raw UUID, in the format
'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'.

=item my $name = $net->get_name()

Returns a string with a locally unique name of the network

=item my $xml = $net->get_xml_description()

Returns an XML document containing a complete description of
the network's configuration

=item $net->create()

Start a network whose configuration was previously defined using the
C<define_network> method in L<Sys::Virt>.

=item $net->undefine()

Remove the configuration associated with a network previously defined
with the C<define_network> method in L<Sys::Virt>. If the network is
running, you probably want to use the C<shutdown> or C<destroy>
methods instead.

=item $net->destroy()

Immediately terminate the machine, and remove it from the virtual
machine monitor. The C<$net> handle is invalid after this call
completes and should not be used again.

=item $net->get_bridge_name()

Return the name of the bridge device associated with the virtual
network

=item $flag = $net->get_autostart();

Return a true value if the virtual network is configured to automatically
start upon boot. Return false, otherwise

=item $net->set_autostart($flag)

Set the state of the autostart flag, which determines whether the
virtual network will automatically start upon boot of the host OS.
