RHBA-2015:1322 - Bug Fix Advisory

Topic

Updated virt-viewer and spice-gtk packages that fix several bugs and add various
enhancements 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.

The spice-gtk packages provide a GIMP Toolkit (GTK+) widget for SPICE (Simple
Protocol for Independent Computing Environments) clients. Both Virtual Machine
Manager and Virtual Machine Viewer can make use of this widget to access virtual
machines using the SPICE protocol.

The virt-viewer packages have been upgraded to upstream version 2.0, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#1179477)

The spice-gtk packages have been upgraded to upstream version 0.26, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#1185434)

This update also fixes the following bugs:

• When using an emulated smart card on a virtual machine, the smart card was not

properly re-initialized after disconnecting and reconnecting the guest. As a
consequence, the smart card became unusable. With this update, the smart card
state is set properly after reconnecting the guest, and no longer becomes
unusable after the operation. (BZ#1205171)

• The first guest display was re-enabled after a guest reboot even when it was

previously disabled on the guest. This update removes the fixed association
between the the main guest window and a specific guest display number, which
prevents the problem from occurring. (BZ#1032936)

• In some monitor configurations, after removing a guest display, the display in

some cases unintendedly reappeared when the virt-viewer tool was started. The
guest now updates its geometry every time a guest display is enabled or
disabled, and guest displays now correctly stay removed. (BZ#1111425)

• When the agent terminated unexpectedly or was disconnected and reconnected

again, virt-viewer did not update the information about windows geometry and the
guest resolution was not restored accordingly. With this update, the function
responsible for updating the displays geometry is called, thus fixing the bug.
(BZ#1021841)

• Using remote-viewer with SSH and the Xming display server caused remote-viewer

to terminate unexpectedly. With this update, an assertion no longer triggers in
the described circumstances, which prevents the crash from occurring.
(BZ#1158086)

• In multi-display guest setups, the mouse input in some cases affected an

incorrect guest display. With this update, displays are properly reordered when
their coordinates change, and mouse input reliably affects the appropriate guest
display. (BZ#1206216)

In addition, this update adds the following enhancements:

• The libgovirt and librest packages have been added to this version of Red Hat

Enterprise Linux, which allows the remote-viewer tool to connect to the oVirt
and Red Hat Enterprise Virtualization virtual machines (VMs). To make it
possible to access these VMs, the new ovirt:// URI scheme has also been added to
remote-viewer. (BZ#981678, BZ#981677, BZ#806925)

• Using the remote-viewer tool to connect to an ovirt:// URI now displays a menu

that allows the user to change the CD image inserted in the virtual machine
(VM). This makes it possible to change the inserted CD while the VM is running
without the need to use Red Hat Enterprise Virtualization or the oVirt portal.
(BZ#975834)

• It is now possible to configure the position in which guest displays in

multi-monitor setups. To do so, edit the ~/.config/virt-viewer/settings file.
For more information about this feature, refer to the CONFIGURATION section of
the remote-viewer(1) manual page. (BZ#1129479)

Users of virt-viewer and spice-gtk are advised to upgrade to these updated
packages, which fix these bugs and add these enhancements.
