Synopsis:          New Parallels Virtuozzo Containers 4.7 tools update provides
                   fixes related to Container management functionality.
Issue date:        05-25-2012
Product:           Parallels Virtuozzo Containers 4.7
Keywords:          "Ubuntu" "EZ template"
--------------------------------------------------------------------------------

1. What's Included in This Update

The new packages for Parallels Virtuozzo Containers 4.7 provide user-level tool
fixes for managing EZ templates and Containers.

2. Problem Description

The new packages introduce the following feature:

- The ability to create and manage Containers based on the Ubuntu 12.04 EZ
  template.

This update contains also fixes for the following issues:

- Unable to create caches for the openSUSE 11.4 EZ template (#PCLIN-30796).

- Containers created via Parallels Operation Automation may fail to start
  (#PCLIN-30853).

- When run on the CentOS 6 host operating system, could return an
  error (#PCLIN-30696).

- Under certain conditions, upgrading the Container template area from VZFS 3
  to VZFS 4 may fail (#PCLIN-30790).

- After upgrade, legacy Containers could run with unlimited physpages
  (#PCLIN-30732).

- A second attempt to migrate a physical server to a Container may fail
  (#PCLIN-30668).

- Removing an IPv6 address from a stopped Container could fail (#PCLIN-30868).

- Online migration of a Container to a node with the SSE4_1 feature could fail
  with an error that the IPv6 module was not loaded on the node (#PCLIN-30480).

All Parallels Containers 4.7 users are advised to update their tools packages.

3. Affected Components

 - "vzctl" is the primary tool for managing Containers. This tool is used
   to create new Containers, start and stop them, configure their parameters,
   etc.

 - "vzmigrate" is a utility for migrating Containers between physical servers.

 - "vzctcalc" is a tool for calculating the disk and memory usage of Containers.

 - "libvznbdmig" is a set of routines that implement the migration of Containers
   to virtual machines.

 - "vzpkgenv*" and "vzpkgenv*x64" are minimal "openSUSE/Debian/Fedora"-like
   environments for executing the Parallels version of the respective package
   manager.

4. Obtaining Update

 You can download and install this tools update using the "vzup2date" utility
 included in the Parallels Containers 4.7 distribution.

5. Installing Update
