8.203. spice-gtk

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

Note

The spice-gtk packages have been upgraded to upstream version 0.19, which provides a number of bug fixes and enhancements over the previous version, including support tunneling through the HTTP proxy server, improved multi-monitor support, and various USB redirection fixes. (BZ#961452)

Bug Fixes

BZ#980400
The polkit utility is built against newer GTK+ and GLib versions, thus it has a runtime dependency on these versions. Previously, upgrading spice-gtk without upgrading GTK+ and GLib at the same time caused applications using polkit to terminate unexpectedly on startup. With this update, the RPM dependencies have been adjusted so that spice-gtk RPMs require new enough versions of GTK+ and GLib. As a result, spice-gtk cannot be installed unless the GTK+ and GLib versions it requires are installed as well.
BZ#879352
Prior to this update, spice-gtk connected to the server plain port by default and succeeded only if the server provided the port. However, this prevented spice-gtk from connecting to a secure port by default. With this update, spice-gtk can connect to secure port instead of always trying plain ports first.
BZ#906558
Previously, if the combination of Shift+CTRL+V keys was pressed on a message window in Microsoft Outlook, the spice-gtk client terminated unexpectedly. To fix this bug, cache palettes of unrendered bitmaps have been applied and the client no longer crashes in the aforementioned scenario.
BZ#998529
When the mouse pointer was placed over a PuTTY session with Microsoft Windows guests, the mouse pointer appeared black. The cursor contrast has been improved and the cursor is now clearly visible when hovering over PuTTY sessions.
BZ#885101
When spice-gtk was connecting to an unreachable host, a connection timeout error took about 2 minutes to occur. With this update, spice-gtk waits for 10 seconds only before reporting an unreachable host error.
BZ#815639
Previously, spice-gtk did not handle correctly an indication that software Smartcard support had already been initialized. Consequently, software Smartcard support stopped working after migration or restarting a guest. As a workaround, do not disable software Smartcard support at spice-gtk connection time if libcacard reports that software Smartcard support is already initialized. Pursuing this workaround, software Smartcard support keeps working across guest reboots or migrations.

Enhancements

BZ#948618
HTTP proxy server support is now available for SPICE clients. The SPICE client now establishes the connection to the remote server by the proxy server specified by the environment SPICE_PROXY=host:port variable, or by the controller.
BZ#752350
Red Hat Enterprise Linux and Microsoft Windows operating systems use different end of line sequences. With this update, a new feature has been implemented, which translates end of line sequences to the target operating system during copy and paste, if the SPICE guest agent has support for this feature.
BZ#978405
Due to high latency and limited bandwidth, a video could become very poorly watchable. With this update, adaptive video streaming with adjusted bandwidth and latency has been implemented, which allows improved video experience over low speed networks.
Users of spice-gtk are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
