NAME

Sys::Virt::NodeDevice - Represent & manage a libvirt storage pool

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(): Returns an XML document containing a complete description of the storage dev's configuration
$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->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.

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::NodeDevice::LIST_CAP_NET: Include devices with the network capability

Sys::Virt::NodeDevice::LIST_CAP_SCSI: Include devices with the SCSI capability
Sys::Virt::NodeDevice::LIST_CAP_SCSI_HOST: Include devices with the SCSI host capability
Sys::Virt::NodeDevice::LIST_CAP_SCSI_TARGET: Include devices with the SCSI target capability
Sys::Virt::NodeDevice::LIST_CAP_STORAGE: Include devices with the storage capability
Sys::Virt::NodeDevice::LIST_CAP_SYSTEM: Include devices with the system capability
Sys::Virt::NodeDevice::LIST_CAP_USB_DEV: Include devices with the USB device capability
Sys::Virt::NodeDevice::LIST_CAP_USB_INTERFACE: Include devices with the USB interface capability
Sys::Virt::NodeDevice::LIST_CAP_FC_HOST: Include devices with the fibre channel host capability
Sys::Virt::NodeDevice::LIST_CAP_VPORTS: Include devices with the NPIV vport capability
Sys::Virt::NodeDevice::LIST_CAP_SCSI_GENERIC: Include devices with the SCSI generic capability
Sys::Virt::NodeDevice::LIST_CAP_DRM: Include devices with the DRM capability

EVENT ID CONSTANTS

Sys::Virt::NodeDevice::EVENT_ID_LIFECYCLE: Node device lifecycle events
Sys::Virt::NodeDevice::EVENT_ID_UPDATE: Node device config update events

LIFECYCLE CHANGE EVENTS

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
