RHBA-2013:0740 - Bug Fix Advisory

Topic

An updated xenpv-win package that fixes multiple bugs is now available for Red
Hat Enterprise Linux 5.

Description

The xenpv-win package contains installation images for para-virtualized drivers
for guests running Microsoft Windows XP or later on Red Hat Enterprise Linux
hosts. Para-virtualized drivers provide significant network and disk I/O
performance improvements for fully virtualized guests over the same guests
running with fully virtualized drivers.

This update fixes the following bugs:

• If a locked Windows 2003 guest with the xenpv-win driver installed was shut

down or rebooted by executing the "xm shutdown" or "xm reboot" command, the
commands became invalid when attempting to execute them again after the machine
was unlocked. The underlying source code has been modified so that Windows 2003
guests can be shut down and rebooted repeatedly regardless of whether the guest
has been locked or not. (BZ#770633)

• Due to a hard-coded 0 index in the code that manipulates the event channel

pending mask, the xenpv-win driver could become unresponsive during boot on EC2
Large Instances. This problem has been fixed, and xenpv-win no longer hangs in
this scenario. (BZ#805669)

• This version of xenpv-win has been certified through the Microsoft Server

Virtualization Validation Platform (SVVP) program. (BZ#844903)

All users of are advised to upgrade to this updated package, which fixes these
bugs.
