RHBA-2012:0380 - Bug Fix Advisory

Topic

An updated xorg-x11-drv-qxl package that fixes two bug is now available for Red
Hat Enterprise Linux 6.

Description

The xorg-x11-drv-qxl package provides 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:

• The QXL driver for Red Hat Enterprise Linux 6.2 did not contain the

compatibility layer. As a consequence, updating a Red Hat Enterprise Linux 6
guest running on a Red Hat Enterprise Linux 5 host in the Red Hat Enterprise
Virtualization 2.2 environment caused the SPICE client window to become black
after the update, and therefore unusable. A patch has been applied to ensure
proper compatibility and the driver now works correctly in the described
scenario. (BZ#794877)

• The QXL driver for Red Hat Enterprise Linux 6.2 was not able to cache images

on the client side. This led to visible and significant impact on user
experience (users could have experienced delays when loading images contained in
web presentations or slideshows). With this update, images can be optionally
cached on the client side. (BZ#799524)

All users of xorg-x11-drv-qxl are advised to upgrade to this updated package,
which fixes these bugs.
