-----------------------------------------------------------------------------

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
backup;

- 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.
