1. ABOUT THIS RELEASE

The current update for the Parallels Server Bare Metal 5.0 kernel provides
a new kernel based on the Red Hat Enterprise Linux 6.3 kernel
(2.6.32-279.14.1.el6). The updated kernel includes a number of security and
stability fixes.

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

2. UPDATES DESCRIPTION

This update contains fixes for the following issues:

* The libc:getlogin() function could return a wrong UID for processes that were
  executed with "vzctl exec" or "vzctl enter" inside a Container running Ubuntu
  12.04. (OVZ 2402)

* The devtmpfs file system permissions were changed to 0755 when mounted
  inside a Container. (PCLIN-31293, OVZ 2397)

* The net interface indexes could be renumbered on a Container shutdown.
  (OVZ 2414)

* When performing an online migration of a Container, a kernel panic could
  occur in the delayfs_preopen() function if an NFS volume was mounted inside
  the Container. (PCLIN-31310)

* When performing an online migration of a Container, a kernel panic could
  occur under heavy network traffic. (OVZ 2407)

* Support for the online migration of POSIX timers was added. This is needed
  in particular to migrate Containers with the running "ntpd" service.
  (PCLIN-31230, OVZ 2324)

* The "perf" package is now built for the Parallels Server Bare Metal 5.0
  kernel. The packages are available for download on the OpenVZ website at
  http://wiki.openvz.org.
