Xenstore: Guests can create orphaned Xenstore nodes By creating multiple
nodes inside a transaction resulting in an error, a malicious guest can
create orphaned nodes in the Xenstore data base, as the cleanup after the
error will not remove all nodes already created. When the transaction is
committed after this situation, nodes without a valid parent can be made
permanent in the data base.
