RHBA-2013:1650 - Bug Fix Advisory

Topic

Updated xorg-x11-drv-qxl packages that fix two bugs are now available for Red
Hat Enterprise Linux 6.

Description

The xorg-x11-drv-qxl packages provide an X11 video driver for the QEMU QXL video
accelerator. This driver makes it possible to use Red Hat Enterprise Linux 6 as
a guest operating system under the KVM kernel module and the QEMU multi-platform
emulator, using the SPICE protocol.

This update fixes the following bugs:

• When the user tried to start a guest with Red Hat Enterprise Linux 6 on a host

with Red Hat Enterprise Linux 5, the QEMU QXL video accelerator failed with a
segmentation fault. As a consequence, the guest was not able to start the system
GUI. This update applies a patch to fix this bug and the guest now starts
correctly. (BZ#929037)

• When using multiple QXL devices with the Xinerama extension, or multiple QXL

devices while each being a separate screen, an attempt to set a resolution
higher than 1024 x 768 pixels in the xorg.conf file failed with an error. With
this update, the underlying source code has been modified and the resolution can
now be set as expected. (BZ#951000)

Users of xorg-x11-drv-qxl are advised to upgrade to these updated packages,
which fix these bugs.
