RHBA-2014:0482 - Bug Fix Advisory

Topic

Updated virt-viewer packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

Description

The virt-viewer packages provide Virtual Machine Viewer, which is a lightweight
interface for interacting with the graphical display of a virtualized guest.
Virtual Machine Viewer uses libvirt and is intended as a replacement for
traditional VNC or SPICE clients. The Simple Protocol for Independent Computing
Environments (SPICE) is a remote display protocol designed for virtual
environments.

This update fixes the following bugs:

• Prior to this update, SPICE determined the scaling of windows incorrectly by

using the original desktop size instead of the host screen size. As a
consequence, when a guest window was open in SPICE, the screen could, under
certain circumstances, become blurry. With this update, the guest window scaling
has been fixed and this problem no longer occurs. (BZ#1081376)

• Previously, the SPICE two-monitor setting did not function as intended.

Consequently, when the guest was set up for two monitors, both of them used only
a single screen while in fullscreen mode. With this update, a fix for the SPICE
two-monitor setting has been implemented and the guest monitors now correctly
appear on their own respective screens when in fullscreen mode. (BZ#1088921)

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