NAME

6       Sys::Virt::NodeDevice - Represent & manage a libvirt storage pool
7

DESCRIPTION

9       The "Sys::Virt::NodeDevice" module represents a storage pool managed by
10       libvirt. There are a variety of storage pool implementations for LVM,
11       Local directories/filesystems, network filesystems, disk partitioning,
12       iSCSI, and SCSI.
13

METHODS

15       my $name = $dev->get_name()
16           Returns a string with a locally unique name of the device
17
18       my $parentname = $dev->get_parent()
19           Returns a string with a locally unique name of the parent of the
20           device, or undef if there is no parent
21
22       my $xml = $dev->get_xml_description()
23           Returns an XML document containing a complete description of the
24           storage dev's configuration
25
26       $dev->reattach()
27           Rebind the node device to the host OS device drivers.
28
29       $dev->dettach()
30           Unbind the node device from the host OS device driver
31
32       $dev->reset()
33           Reset the node device. The device must be unbound from the host OS
34           drivers for this to work
35
36       $dev->create($flags=0)
37           Start a node device whose configuration was previously defined
38           using the "define_node_device" method in Sys::Virt. The $flags
39           parameter is currently unused and defaults to zero.
40
41       $dev->undefine($flags=0)
42           Delete a node device whose configuration was previously defined
43           using the "define_node_device" method in Sys::Virt. The $flags
44           parameter is currently unused and defaults to zero.
45
46       $flag = $dev->get_autostart();
47           Return a true value if the node device is configured to
48           automatically start upon boot. Return false, otherwise
49
50       $dev->set_autostart($flag)
51           Set the state of the autostart flag, which determines whether the
52           node device will automatically start upon boot of the host OS.
53
54       $dev->is_active()
55           Returns a true value if the node device is currently running
56
57       $dev->is_persistent()
58           Returns a true value if the node device has a persistent
59           configuration file defined
60
61       $dev->destroy()
62           Destroy the virtual device releasing any OS resources associated
63           with it.
64
65       my @caps = $dev->list_capabilities()
66           Return a list of all capabilities in the device.
