Synopsis: New Virtuozzo 3.0.0 tools update provides fixes related to
  backup functionality and Debian-based EZ templates
Issue date: 2007-05-31
Product: Virtuozzo 3.0.0
Keywords: vzbackup vzctl ez

1. Topic:

 Updated packages for Virtuozzo 3.0.0 providing user-level tools fixes
 for backup functionality, a number of minor fixes for existing vzctl issues,
 and an updated package environment for Debian-based EZ templates.

2. Problem description:

 - Restoring a VE fails if the VE_PRIVATE path was customized;

 - Backing up a VE fails if the vzfs tracker stops running;

 - VEs backed up on a Node with disabled disk quotas cannot be restored on
  Nodes having these quotas enabled;

 - When more than one VE are backed up simultaneously, the backup-related
  parameters from the configuration file of the first VE to be backed up
  are applied to all the successive VEs;

 - vzbackup does not handle an error from 'hostname -f';

 - vzrestore can't find archive, if there are symlinks in the path to the VE

 - It is possible to set UBC limits if the SLMMODE parameter in the VE
  configuration file is set to 'slm';

 - If it has been granted access to a number of devices via --devnodes or
  --devices, a VE can access only the first one of them;

 - It is impossible to install some recent Debian packages into a VE.

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

3. Affected components description:

 - vzbackup is a tool for backing up and restoring Virtual Environments.

 - 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.
