RHBA-2016:1536 - Bug Fix Advisory

Topic

Updated virt-viewer and libgovirt packages that fix several bugs and add one enhancement are now available for Red Hat Enterprise Linux 7.

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 libgovirt packages contain a library that allows applications to use the oVirt Representational State Transfer (REST) API to list virtual machines (VMs) managed by an oVirt instance. The library is also used to get the connection parameters needed to establish a connection to the VMs using Simple Protocol For Independent Computing Environments (SPICE) or Virtual Network Computing (VNC).

This update fixes the following bugs:

• Prior to this update, closing a virt-viewer console by using the checkbox in the View -> Displays menu in some cases caused virt-viewer to terminate unexpectedly. This update fixes the underlying code, and thus prevents the described problem from occurring. (BZ#1354283)
• Using the remote-viewer console to connect to a remote guest machine on Red Hat Enterprise Virtualization 4.0 in some cases failed because the state of the guest was not detected accurately. This update corrects a syntax error in the REST API that was causing this problem, and remote-viewer now opens the described guests more reliably. (BZ#1354286)
• Previously, opening a remote guest console with the remote-viewer utility in the Red Hat Enterprise Virtualization Manager caused the event log to be flooded with the "Refresh image list succeeded for domain(s)" message. This update significantly lowers the frequency of displaying messages about refreshing image list, so that they no longer flood the guest event log. (BZ#1353627)

In addition, this update adds the following enhancement:

• The virt-viewer and libgovirt packages have been updated to adjust to authentication changes in Red Hat Enterprise Virtualization 4.0. This ensures that the foreign menu continues working correctly on Red Hat Enterprise Virtualization 4.0 when starting the remote-viewer utility using the web portal interface. Note, however, that the menu does not work when starting remote-viewer from the command line. (BZ#1344633, BZ#1344635)

Users of virt-viewer and libgovirt are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
