RHBA-2013:1037 - Bug Fix Advisory

Topic

Updated spice-server packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

The Simple Protocol for Independent Computing Environments (SPICE) is a remote
display protocol for virtual environments. SPICE users can access a virtualized
desktop or server from the local system or any system with network access to the
server. SPICE is used in Red Hat Enterprise Linux for viewing virtualized guests
running on the Kernel-based Virtual Machine (KVM) hypervisor or on Red Hat
Enterprise Virtualization Hypervisors.

This update fixes the following bug:

• Previously, qemu-kvm terminated with the following error message,

"((null):3635): SpiceWorker-CRITICAL **: red_worker.c:9306:red_create_surface:
Untested path stride >= 0." The spice-server did not allow creation of a surface
with "stride >= 0," as this path of code was untested, and no qxl driver did
this before. On some systems, spice-server terminated when the qxl driver tried
creating a surface with the "stride >= 0" path. With this update, spice-server
no longer checks for the "stride >=0" path, and VMs with qxl devices are able to
run and use their qxl driver. (BZ#973703)

Users of spice-server are advised to upgrade to these updated packages, which
fix this bug.
