Updated xorg-x11-drv-qxl packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
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.
- 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.
- 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.
Users of xorg-x11-drv-qxl are advised to upgrade to these updated packages, which fix these bugs.
