RHBA-2011:1542 - Bug Fix Advisory

Topic

An updated virtio-win package that fixes two bugs is now available for Red Hat
Enterprise Linux 6.

Description

The virtio-win package provides paravirtualized network drivers for most Windows
operating systems.

The RHBA-2011:0782 virtio-win bug fix and enhancement update did not completely
resolve the following issue, which is now fully fixed:

• Previously, the netperf test on the Windows 2008 and Windows 7 guests with

virtio network caused the network to become unresponsive. This update corrects
the Network Interface Card (NIC) driver. Now, the network stays available.
(BZ#706791)

This update also fixes the following bugs:

• Previous versions of virtio-win did not include the QXL driver. As a result,

the QXL driver could not be installed from the same installation media as the
virtio network or block driver. This update adds QXL drivers to the virtio-win
installation media. This allows to install and update QXL drivers without
requiring the MSI installer. (BZ#726883)

• The NetKVM driver included in the previous version of virtio-win had a lower

version number than the same driver in Red Hat Enterprise Virtualization
Manager. It was therefore impossible to update the NetKVM driver when upgrading
from Red Hat Enterprise Virtualization 2.2 to 3.0. The most recent NetKVM
driver, WHQL (Windows Hardware Quality Labs) signed, takes advantage of the new
version numbering scheme, which changed the driver version number to be much
higher that before. Users are now able to upgrade the NetKVM driver flawlessly
when upgrading from Red Hat Enterprise Virtualization 2.2 to 3.0. (BZ#728982)

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