RHEA-2016:1671 - Product Enhancement Advisory

Topic

Updated vdsm packages that fix several bugs and add various enhancements are now available.

Description

VDSM is a management module that serves as a Red Hat Enterprise Virtualization Manager agent on Red Hat Virtualization Host or Red Hat Enterprise Linux hosts.

Changes to the vdsm component:

• Previously, package dependencies were not set correctly, preventing deployment of ppc64le hosts. These dependencies have now been corrected. (BZ#1339464)
• Previously, incorrect handling of internal status updates in VDSM caused API calls to fail with unexpected exceptions. This triggered insufficient error handling in MOM, causing the MOM process to crash. Now, the internal status update handling of VDSM has been improved, reducing the impact of MOM crashes. The complete fix requires improvements in MOM, tracked in a different bug. (BZ#1318550)
• Previously, when creating snapshots the backing volume reference included an image directory component. Each time a snapshot was merged, the image directory component of the backing volume reference was duplicated until the backing volume reference became too long. In this state the image could not be used. Now, since all volumes of an image always reside in the same directory the image directory component has been removed from new backing volume references. Now the backing volume references do not grow in length after snapshots are merged. (BZ#1333627)
