RHBA-2013:0308 - Bug Fix Advisory

Topic

Updated xorg-x11-drv-qxl packages that fix multiple bugs and add various
enhancements 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.

The xorg-x11-drv-qxl packages have been upgraded to upstream version 0.1.0,
which adds support for multiple monitors and continuous resolution. It aslo
provides a number of bug fixes and enhancements over the previous version.
(BZ#835249, BZ#787160)

This update also fixes the following bugs:

Due to overlapping memory areas, remote-viewer became unresponsive after a
migration of a guest playing a video. This update adjusts the monitors_config
pointer to fix this issue, and migration of a guest, which is displaying video,
works as expected. (BZ#883578)

This update disables "surfaces" by default due to a performance regression with
the rendering support. (BZ#896005)

All users of xorg-x11-drv-qxl are advised to upgrade to these updated packages,
which fix these bugs and add these enhancements.
