EVENTIDCONSTANTS
Sys::Virt::NodeDevice::EVENT_ID_LIFECYCLE
Node device lifecycle events
Sys::Virt::NodeDevice::EVENT_ID_UPDATE
Node device config update events
LIFECYCLECHANGEEVENTS
The following constants allow node device lifecycle change events to be interpreted. The events contain
both a state change, and a reason though the reason is currently unused.
Sys::Virt::NodeDevice::EVENT_CREATED
Indicates that a device was created
Sys::Virt::NodeDevice::EVENT_DELETED
Indicates that a device has been deleted
Sys::Virt::NodeDevice::EVENT_DEFINED
Indicates that a device configuration has been created
Sys::Virt::NodeDevice::EVENT_UNDEFINED
Indicates that a device configuration has been deleted
NODEDEVICECREATION
Sys::Virt::NodeDevice::CREATE_XML_VALIDATE
Validate the XML document against schema
NODEDEVICEDEFINE
Sys::Virt::NodeDevice::DEFINE_XML_VALIDATE
Validate the XML document against schema
NODEDEVICEUPDATE
Sys::Virt::NodeDevice::UPDATE_AFFECT_CURRENT
Affect live if node device is active, config if it's not active
Sys::Virt::NodeDevice::UPDATE_AFFECT_LIVE
Affect live state of node device only
Sys::Virt::NodeDevice::UPDATE_AFFECT_CONFIG
Affect persistent config only
XMLDUMPOPTIONS
The following constants are used to control the information included in the XML configuration dump
Sys::Virt::NodeDevice::XML_INACTIVE
Report the persistent inactive configuration for the node device.

Description
The "Sys::Virt::NodeDevice" module represents a storage pool managed by libvirt. There are a variety of
storage pool implementations for LVM, Local directories/filesystems, network filesystems, disk
partitioning, iSCSI, and SCSI.

Methods
my $name = $dev->get_name()
Returns a string with a locally unique name of the device
my $parentname = $dev->get_parent()
Returns a string with a locally unique name of the parent of the device, or undef if there is no
parent
my $xml = $dev->get_xml_description($flags=0)
Returns an XML document containing a complete description of the node device's configuration. The
optional $flags parameter controls generation of the XML document, defaulting to 0 if omitted. It can
be one or more of the XML DUMP constants listed later in this document.
$dev->reattach()
Rebind the node device to the host OS device drivers.
$dev->dettach()
Unbind the node device from the host OS device driver
$dev->reset()
Reset the node device. The device must be unbound from the host OS drivers for this to work
$dev->create($flags=0)
Start a node device whose configuration was previously defined using the "define_node_device" method
in Sys::Virt. The $flags parameter is currently unused and defaults to zero.
$dev->undefine($flags=0)
Delete a node device whose configuration was previously defined using the "define_node_device" method
in Sys::Virt. The $flags parameter is currently unused and defaults to zero.
$flag = $dev->get_autostart();
Return a true value if the node device is configured to automatically start upon boot. Return false,
otherwise
$dev->set_autostart($flag)
Set the state of the autostart flag, which determines whether the node device will automatically
start upon boot of the host OS.
$dev->is_active()
Returns a true value if the node device is currently running
$dev->is_persistent()
Returns a true value if the node device has a persistent configuration file defined
$dev->destroy()
Destroy the virtual device releasing any OS resources associated with it.
my @caps = $dev->list_capabilities()
Return a list of all capabilities in the device.
$dev->update($xml, $flags=0)
Update the definition of an existing node device with $xml. The $flags parameter can be use to
control which config is affected (see XML UPDATE FLAGS) and defaults to zero (affect current state of
the node device).
