1. ABOUT THIS UPDATE

The current update for the Parallels Virtuozzo Containers 4.7 kernel provides a
new kernel based on the Red Hat Enterprise Linux 6.4 kernel
(2.6.32-358.18.1.el6). The updated kernel includes a number of stability fixes.

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

2. UPDATE DESCRIPTION

This update includes the following fixes:

* The file system of a VZFS-based Container could remain frozen after a backup,
  resulting in processes being stuck on disk I/O operations.
  (PCLIN-32011, PCLIN-32055)

* Under certain circumstances, the filesystem freeze operation could still
  pass writes to disk, which could cause online migration failures. (PSBM-22372)

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

3. OBTAINING THE NEW KERNEL

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