NAME

       Sys::Virt::Network - Represent & manage a libvirt virtual network

DESCRIPTION

       The "Sys::Virt::Network" module represents a virtual network managed by the virtual
       machine monitor.

METHODS

       my $uuid = $net->get_uuid()
           Returns a 16 byte long string containing the raw globally unique identifier (UUID) for
           the network.

       my $uuid = $net->get_uuid_string()
           Returns a printable string representation of the raw UUID, in the format
           'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'.

       my $name = $net->get_name()
           Returns a string with a locally unique name of the network

       $net->is_active()
           Returns a true value if the network is currently running

       $net->is_persistent()
           Returns a true value if the network has a persistent configuration file defined

       my $xml = $net->get_xml_description()
           Returns an XML document containing a complete description of the network's
           configuration

       $net->create()
           Start a network whose configuration was previously defined using the "define_network"
           method in Sys::Virt.

       $net->undefine()
           Remove the configuration associated with a network previously defined with the
           "define_network" method in Sys::Virt. If the network is running, you probably want to
           use the "shutdown" or "destroy" methods instead.

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

       $net->update($command, $section, $parentIndex, $xml, $flags=0)
           Update the network configuration with $xml. The $section parameter, which must be one
           of the XML SECTION CONSTANTS listed later, indicates what schema is used in $xml. The
           $command parameter determines what action is taken. Finally, the $flags parameter can
           be use to control which config is affected.

       $net->get_bridge_name()
           Return the name of the bridge device associated with the virtual network

       $flag = $net->get_autostart();
           Return a true value if the virtual network is configured to automatically start upon
           boot. Return false, otherwise

       $net->set_autostart($flag)
           Set the state of the autostart flag, which determines whether the virtual network will
           automatically start upon boot of the host OS.

       @leases = $net->get_dhcp_leases($mac=undef, $flags=0)
           Get a list of all active DHCP leases. If $mac is undefined than leases for all VMs are
           returned, otherwise only leases for the matching MAC address are returned. The $flags
           parameter is currently unused and defaults to zero.

           The elements in the returned array are hash references with the following fields

           "iface"
               Network interface name

           "expirytime"
               Seconds since the epoch until the lease expires

           "type"
               One of the Sys::Virt IP address type constants

           "mac"
               The MAC address of the lease

           "iaid"
               The IAID of the client

           "ipaddr"
               The IP address of the lease

           "prefix"
               The IP address prefix

           "hostname"
               The optional hostname associated with the lease

           "clientid"
               The client ID or DUID
