Synopsis: New Virtuozzo 3.0.0 tools update provides fixes related to
  Virtual Environments networking and package management
Issue date: 2007-11-09
Product: Virtuozzo 3.0.0
Keywords: vzctl vznetcfg vztt ez

1. Topic:

 Updated packages for Virtuozzo 3.0.0 providing user-level tools fixes for
 VE networking and package management functionality.

2. Problems description:

 - Starting a VE in the wait mode takes a lot of time, if no hostname for this
  VE has been specified.

 - It is impossible to use the ipt_owner iptables module inside VEs.

 - It is impossible to start a VE with the resolvconf package installed.

 - If a physical interface is attached to a bridge where one or more VETH
  interfaces are already attached, all of them will be detached from the

 - Attaching a bonding interface to a bridge leads to a network connection

 - VEs based on a Debian EZ template can be unusable after the migration to
  another Hardware Node, because vzpkg repair might not return a proper error
  code during the migration and some VZFS magic symlinks are pointing nowhere.

 - It is impossible to use EZ templates on the Nodes with vzt-3.0.0-61 installed
  and Red Hat Enterprise Linux 3.0 host OS.

 - It is impossible to use the SuSE 10.2 and 10.3 OS EZ templates because of no
  support for BuiltinLuaScripts in the current chroot environment.

 All Virtuozzo 3.0.0 users are advised to update their tools packages.

3. Affected components description:

 - vzctl is the primary tool for Virtual Environment management. This tool is
  used to create new VEs, start and stop them, configure their parameters, etc.

 - vznetcfg is a utility used to manage Virtuozzo networks and VLANs on the
  Hardware Node.

 - vztt is a set of tools for managing EZ (easy) templates. This type of
  templates was first introduced in Virtuozzo 3.0.0 and is supposed to be more
  flexible and easy to manage than standard templates.

4. Bug fixes:

 #93219 - slow VE creation

 #93451 - ipt_owner mask should be added to vzctl

 #83936 - VETH is dropped from the bridge after physical interface is added to

 #92872 - broken 'br attach' of bonding interface

 #78794 - broken 'vzpkg repair' for debian-based templates

 #93691 - fixed mirrorlist processing on redhat-as3
