1. ABOUT THIS RELEASE

The current update for the Virtuozzo Containers 4.7 kernel provides a new
kernel based on the Red Hat 6.1 kernel (2.6.32-131.21.1.el6). The updated
kernel includes stability fixes and provides support for the openSUSE 12.1 OS
template.

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

2. UPDATES DESCRIPTION

This update contains fixes for the following issues:

* Under certain conditions, a kernel panic could occur while processing network
  traffic in bridged mode. (PSBM-10853)

* When creating a new user, PostgreSQL could get stuck in the step of confirming
  the user name if running inside a Container based on the openSUSE 12.1 template.
  (PCLIN-30612)

* A Container backup process could cause a kernel panic if the /vz partition
  was previously shrunk. (PCLIN-30610)

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

3. OBTAINING NEW KERNEL

You can download and install this kernel update using the vzup2date utility
included in the Parallels Virtuozzo Containers 4.7 distribution set.

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

4. INSTALLING NEW KERNEL

To install the update, do the following:

I. Use the "rpm -ihv" command to install the new kernel and Virtuozzo modules.

# rpm -ivh vzkernel-2.6.32-042stab044.17.i686.rpm \
vzmodules-2.6.32-042stab044.17.i686.rpm
Preparing...                ################################# [100%]
    1:vzkernel               ################################# [50%]
    2:vzmodules              ################################# [100%]

    DO NOT USE the "rpm -Uhv" command to install the kernel. If you do,
    all previously installed kernels on your system may be removed from
    the Hardware Node.

II. You can adjust your boot loader configuration file so that the new kernel
    is loaded by default. If you use the LILO bootloader, do not forget to
    execute the "lilo" command to write the changes to the boot sector:

     # lilo
     Added Virtuozzo2 *
     Added Virtuozzo1
     Added linux
     Added linux-up

III. Reboot your computer with the "shutdown -r now" command to boot the new
     kernel.
