Sys::Virt::Network(3pm) User Contributed Perl Documentation 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 @port = $net->list_all_ports($flags=0) List all ports associated with the network. The return array elements are instances of the "Sys::Virt::NetworkPort" class. $port = $net->create_port($xml, $flags=0) Create a new network port from the given $xml description. The $flags parameter can optionally taken one or more of the network port creation constants. The returned $port object is an instance of the "Sys::Virt::NetworkPort" class. $port = $net->get_port_by_uuid($uuid); Lookup a network port from a raw or printable UUID. The returned $port object is an instance of the "Sys::Virt::NetworkPort" class. CONSTANTS This section documents constants that are used with various APIs described above NETWORK CREATION CONSTANTS When creating networks zero or more of the following constants may be used Sys::Virt::Network::CREATE_VALIDATE Validate the XML document against the XML schema LIST FILTERING The following constants are used to filter object lists Sys::Virt::Network::LIST_ACTIVE Include networks which are active Sys::Virt::Network::LIST_INACTIVE Include networks which are not active Sys::Virt::Network::LIST_AUTOSTART Include networks which are set to autostart Sys::Virt::Network::LIST_NO_AUTOSTART Include networks which are not set to autostart Sys::Virt::Network::LIST_PERSISTENT Include networks which are persistent Sys::Virt::Network::LIST_TRANSIENT Include networks which are transient NETWORK DEFINE The following constants can be used to control the behaviour of network define operations Sys::Virt::Network::DEFINE_VALIDATE Validate the XML document against the XML schema XML CONSTANTS The following constants are used when querying XML Sys::Virt::Network::XML_INACTIVE Request the inactive XML, instead of the current possibly live config. XML SECTION CONSTANTS The following constants are used to refer to sections of the XML document Sys::Virt::Network::SECTION_BRIDGE The bridge device element Sys::Virt::Network::SECTION_DNS_HOST The DNS host record section Sys::Virt::Network::SECTION_DNS_SRV The DNS SRV record section Sys::Virt::Network::SECTION_DNS_TXT The DNS TXT record section Sys::Virt::Network::SECTION_DOMAIN The domain name section Sys::Virt::Network::SECTION_FORWARD The forward device section Sys::Virt::Network::SECTION_FORWARD_INTERFACE The forward interface section Sys::Virt::Network::SECTION_FORWARD_PF The forward physical function section Sys::Virt::Network::SECTION_IP The IP address section Sys::Virt::Network::SECTION_IP_DHCP_HOST The IP address DHCP host section Sys::Virt::Network::SECTION_IP_DHCP_RANGE The IP address DHCP range section Sys::Virt::Network::SECTION_PORTGROUP The port group section Sys::Virt::Network::SECTION_NONE The top level domain element XML UPDATE FLAGS Sys::Virt::Network::UPDATE_AFFECT_CURRENT Affect whatever the current object state is Sys::Virt::Network::UPDATE_AFFECT_CONFIG Always update the config file Sys::Virt::Network::UPDATE_AFFECT_LIVE Always update the live config XML UPDATE COMMANDS Sys::Virt::Network::UPDATE_COMMAND_NONE No update Sys::Virt::Network::UPDATE_COMMAND_DELETE Remove the matching entry Sys::Virt::Network::UPDATE_COMMAND_MODIFY Modify the matching entry Sys::Virt::Network::UPDATE_COMMAND_ADD_FIRST Insert the matching entry at the start Sys::Virt::Network::UPDATE_COMMAND_ADD_LAST Insert the matching entry at the end EVENT ID CONSTANTS Sys::Virt::Network::EVENT_ID_LIFECYCLE Network lifecycle events LIFECYCLE CHANGE EVENTS The following constants allow network lifecycle change events to be interpreted. The events contain both a state change, and a reason though the reason is currently unused. Sys::Virt::Network::EVENT_DEFINED Indicates that a persistent configuration has been defined for the network. Sys::Virt::Network::EVENT_STARTED The network has started running Sys::Virt::Network::EVENT_STOPPED The network has stopped running Sys::Virt::Network::EVENT_UNDEFINED The persistent configuration has gone away AUTHORS Daniel P.
