An updated xorg-x11-drv-qxl package that fixes various bugs is now available.
xorg-x11-qxl-drv is 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 KVM and QEMU, using the SPICE protocol.
This updated xorg-x11-drv-qxl package includes fixes for the following bugs:
When using the xql driver, only a limited number of resolution choices were available for use inside the guest, none of which exceeded 1024x768 in size unless the xorg.conf configuration file was (first created, and then) manually edited. This update ensures that larger resolutions are available for guests with appropriate hardware without needing to manually change xorg.conf.
When using the qxl driver, after connecting to a virtual guest over the SPICE protocol and logging into a desktop session from the GDM display manager, attempting to switch to a virtual console using a key combination caused the X server to crash, and GDM to respawn. This update fixes this issue so that, in the aforementioned situation, switching to a virtual console and back to the graphical desktop works as expected.
All users of KVM-based virtualization are advised to upgrade to this updated package, which fixes these issues.
