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.

           Indicates that a device was created

       Sys::Virt::NodeDevice::EVENT_DELETED
           Indicates that a device has been deleted
