NAME

6       Sys::Virt::Network - Represent & manage a libvirt virtual network
7

DESCRIPTION

9       The "Sys::Virt::Network" module represents a virtual network managed by
10       the virtual machine monitor.
11

METHODS

13       my $uuid = $net->get_uuid()
14           Returns a 16 byte long string containing the raw globally unique
15           identifier (UUID) for the network.
16
17       my $uuid = $net->get_uuid_string()
18           Returns a printable string representation of the raw UUID, in the
19           format 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'.
20
21       my $name = $net->get_name()
22           Returns a string with a locally unique name of the network
23
24       $net->is_active()
25           Returns a true value if the network is currently running
26
27       $net->is_persistent()
28           Returns a true value if the network has a persistent configuration
29           file defined
30
31       my $xml = $net->get_xml_description()
32           Returns an XML document containing a complete description of the
33           network's configuration
34
35       $net->create()
36           Start a network whose configuration was previously defined using
37           the "define_network" method in Sys::Virt.
38
39       $net->undefine()
40           Remove the configuration associated with a network previously
41           defined with the "define_network" method in Sys::Virt. If the
42           network is running, you probably want to use the "shutdown" or
43           "destroy" methods instead.
44
45       $net->destroy()
46           Immediately terminate the machine, and remove it from the virtual
47           machine monitor. The $net handle is invalid after this call
48           completes and should not be used again.
49
50       $net->update($command, $section, $parentIndex, $xml, $flags=0)
51           Update the network configuration with $xml. The $section parameter,
52           which must be one of the XML SECTION CONSTANTS listed later,
53           indicates what schema is used in $xml. The $command parameter
54           determines what action is taken. Finally, the $flags parameter can
55           be use to control which config is affected.
56
57       $net->get_bridge_name()
58           Return the name of the bridge device associated with the virtual
59           network
60
61       $flag = $net->get_autostart();
62           Return a true value if the virtual network is configured to
63           automatically start upon boot. Return false, otherwise
64
65       $net->set_autostart($flag)
66           Set the state of the autostart flag, which determines whether the
67           virtual network will automatically start upon boot of the host OS.
68
69       @leases = $net->get_dhcp_leases($mac=undef, $flags=0)
70           Get a list of all active DHCP leases. If $mac is undefined than
71           leases for all VMs are returned, otherwise only leases for the
72           matching MAC address are returned. The $flags parameter is
73           currently unused and defaults to zero.
74
75           The elements in the returned array are hash references with the
76           following fields
77
78           "iface"
79               Network interface name
80
81           "expirytime"
82               Seconds since the epoch until the lease expires
83
84           "type"
85               One of the Sys::Virt IP address type constants
86
87           "mac"
88               The MAC address of the lease
89
90           "iaid"
91               The IAID of the client
92
93           "ipaddr"
94               The IP address of the lease
95
96           "prefix"
97               The IP address prefix
98
99           "hostname"
100               The optional hostname associated with the lease
101
102           "clientid"
103               The client ID or DUID
104
105       @port = $net->list_all_ports($flags=0)
106           List all ports associated with the network. The return array
107           elements are instances of the "Sys::Virt::NetworkPort" class.
108
109       $port = $net->create_port($xml, $flags=0)
110           Create a new network port from the given $xml description. The
111           $flags parameter can optionally taken one or more of the network
112           port creation constants. The returned $port object is an instance
113           of the "Sys::Virt::NetworkPort" class.
114
115       $port = $net->get_port_by_uuid($uuid);
116           Lookup a network port from a raw or printable UUID.  The returned
117           $port object is an instance of the "Sys::Virt::NetworkPort" class.
