NAME
       Sys::Virt::DomainSnapshot - Represent & manage a libvirt guest domain

DESCRIPTION
       The "Sys::Virt::DomainSnapshot" module represents a guest domain managed by the virtual machine monitor.

METHODS
       my $str = $domss->get_name()
	   Return the name of the snapshot

       my $xml = $domss->get_xml_description($flags)
	   Returns an XML document containing a complete description of the domain's configuration.

       $domss->delete($flags)
	   Deletes this snapshot object & its data. The optional $flags parameter controls what should be deleted via the
	   "Sys::Virt::DomainSnapshot::DELETE_*" constants.

       $domss->revert_to($flags)
	   Revert the domain to the state associated with this snapshot. The optional $flags control the state of the vm after the revert via the
	   "Sys::Virt::DomainSnapshot::REVERT_*" constants.

       $parentss = $domss->get_parent();
	   Return the parent of the snapshot, if any

       $count = $domss->num_of_child_snapshots()
	   Return the number of saved snapshots which are children of this snapshot

       @names = $domss->list_child_snapshot_names()
	   List the names of all saved snapshots which are children of this snapshot . The names can be used with the "lookup_snapshot_by_name"

       @snapshots = $domss->list_child_snapshots()
	   Return a list of all snapshots that are children of this snapshot. The elements in the returned list are instances of the
	   Sys::Virt::DomainSnapshot class.
