RHBA-2012:0888 - Bug Fix Advisory

Topic

Updated spice-client packages that fix several bugs and add multiple
enhancements are now available for Red Hat Enterprise Linux 6.

Description

The spice-client package provides the Simple Protocol for Independent Computing
Environments (SPICE) client application. SPICE is a remote display protocol
designed 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 KVM hypervisor or on Red Hat Enterprise Virtualization Hypervisors.

Bug fixes:

• The SPICE client did not pass the volume multimedia keys events to the guest

operating system. Therefore, it was not possible to change the guest's volume
with these keys. Usage of the multimedia keys is now correctly caught by the
client and passed to the guest system. (BZ#552539)

• In certain special multiscreen setups, after switching to full-screen mode and

then quitting the SPICE client, the physical client screen turned off due to a
bug in the code handling resolution switching. This updates fixes the code and
the problem no longer occurs. (BZ#693431)

• The SPICE client did not properly support the Xinerama extension in

full-screen mode on multi-screen setups. Therefore, if the user switched to
full-screen mode while using Xinerama, SPICE client windows failed to cover all
physical screens used by the guest. This update improves Xinerama support and
the SPICE client now behaves correctly in full-screen mode. (BZ#695323)

• Sound recording in the guest failed when another application was accessing the

recording device on the SPICE client start-up. The client now uses the
PulseAudio sound server, which allows multiple applications to access the
recording device at the same time. (BZ#711810)

• The Red Hat Enterprise Virtualization console accessible from User Portal

failed to open and returned error code 1032. This occurred on certain
non-English locales as the value of the localized keyboard modifier was not
considered a legal value of the hot-keys property. With this update, the hot-key
value is parsed correctly even if unrecognized by the parser and falls back to
its default value in such case. (BZ#750030)

• USB Auto-Share did not work on the initial full-screen of a SPICE session and

a USB device could remain inaccessible unless the user switched focus to a
different application and then back to the SPICE-client window. This occurred
due to a race condition in the underlying code. The code has been modified and
the problem no longer occurs. (BZ#791269)

• The SPICE context (right-click) menu was not always available in the client.

The context menu was not displayed on clients where the USB Redirector Service
was installed but not started and the user switched to window mode. The SPICE
client has been updated and the context menu is now always available in window
mode. (BZ#791271)

• Starting the SPICE client from the Red Hat Enterprise Virtualization portal

failed when the local username was too long. With this update, the code has been
modified and they are no longer constrains on the username length. (BZ#804561)

Enhancements:

• Support for receiving a controller message telling the client to enable

smart-card support has been added. (BZ#696075)

• The SPICE client is now able to handle requests from the Red Hat Enterprise

Virtualization portal to enable or disable passing of the Ctrl+Alt+Delete key
combination to the guest operating system. (BZ#750856)

All users of spice-client are advised to upgrade to these updated packages,
which fix these bugs and add these enhancements.
