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.
