1. What's Included in This Update

the following user-level tool fixes:
 - managing Containers using the 'vzctl' utility

   cause network problems in the Container.
 - Traffic shaping works incorrectly for bonding devices.

 - It is impossible to move a Container from one Hardware Node to another if the
   disk quota is disabled for the Container.
 - Moving a Container, that was created by migrating a physical server, to
   another Node may fail.

 - Online CT migration fails on a shared NFS storage.
