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.

CONSTANTS

This section documents constants that are used with various APIs described above

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

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 unsed.

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
