virt-viewer bug fix and enhancement update

Type/Severity

Product Enhancement Advisory

Topic

An updated virt-viewer package that fixes several bugs and adds one enhancement
is now available for Red Hat Enterprise Linux 6.

Description

Virtual Machine Viewer (virt-viewer) is a lightweight interface for interacting
with the graphical display of a virtualized quest. It uses libvirt and is
intended as a replacement for traditional VNC clients.

The virt-viewer package has been upgraded to upstream version 0.4.1, which
provides support for The Simple Protocol for Independent Computing Environments
(SPICE) multihead setups. (BZ#680213)

This update also fixes the following bugs:

• Running the virt-viewer utility with the "--verbose" or "-v" option did not
  display verbose information. With this update, additional data has been provided
  so that the command outputs detailed information. (BZ#680331)
  
• Previously, the virt-viewer utility failed to connect to remote displays when
  using SSH tunneling with the SSH server on a non-standard port number. An
  upstream patch has been applied to address this issue and virt-viewer now
  correctly displays remote quests. (BZ#730346)
  
• Previously, running the "virt-viewer --zoom" command with a zoom level
  specified did not work correctly. This update fixes the initial zoom level on a
  display, and the primary window zoom level is now propagated to secondary
  windows. As a result, the zoom option works as expected. (BZ#730901)
  
• Using a wildcard address (for example, 0.0.0.0) as a listen address for the
  graphic server could cause virt-viewer to fail to connect to remote virtual
  machines. If the user used the "virt-viewer --direct --connect" command with a
  remote IP address to connect a virtual machine, virt-viewer connected to the
  graphic server but was not able to connect to the virtual machine. The hostname
  is now used from the libvirt URI and virt-viewer can open remote virtual
  machines successfully. (BZ#730911)
  
• Due to an invalid implementation of the libvirt events API, the virt-viewer
  utility occasionally resulted in a deadlock. To avoid deadlock situations, ff
  callbacks are now invoked from a clean stack instead of being called directly
  from the remote callback. (BZ#731132)
  
• Previously, the window titles for virt-viewer instances did not contain the
  name of the displayed guest, nor did they contain the number of guest displays
  (for multihead setups). The source code has been modified so that the titles now
  contain both the name of the guest and the number of displays. (BZ#739007)
  
• Guests are normally configured with their VNC (Virtual Network Computing)
  server on a TCP socket, but can be also configured to use a UNIX domain socket
  instead. Prior to this update, virt-viewer was unable to connect to such a guest
  and terminated unexpectedly with a segmentation fault when attempting to open
  it. A patch has been applied to address the issue and the virt-viewer utility
  now opens guests successfully and no longer crashes. (BZ#740724)
  
• Due to certain broken key combinations, sending the Ctrl+Alt+F9 and
  Ctrl+Alt+F10 key combinations incorrectly opened the tty4 and tty5 text consoles
  in virt-viewer. This update fixes the broken key combinations and the text
  console no longer opens when sending the aforementioned key combinations.
  (BZ#744370)
  
• Previously, the window title was missing the guestname when waiting for a
  domain to start. To fix this problem, the initial window title is set to the
  "--wait" command line argument while waiting for a virtual machine to start.
  When the machine actually appears, the title is updated to the real name of the
  machine. (BZ#744374)
  
• With the SPICE (Simple Protocol for Independent Computing Environments)
  graphics, the virt-viewer windows did not display the "Press Ctrl+Alt to release
  pointer" information. With this update, VirtViewerDisplaySpice is connected to
  the grab signals in DisplaySpice, which ensures that the release sequence
  message is now displayed. (BZ#744377)
  

Users are advised to upgrade to this updated virt-viewer package, which fixes
these bugs and adds this enhancement.
