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

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.

Returns a string with a locally unique name of the device
Returns a string with a locally unique name of the parent of the device, or undef if there is no parent
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
$dev->create($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.
Return a list of all capabilities in the device.

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

EVENT ID CONSTANTS

Node device lifecycle events
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.

Indicates that a device was created
Indicates that a device has been deleted
Indicates that a device configuration has been created
Indicates that a device configuration has been deleted
