RHBA-2020:3822 - Bug Fix Advisory

Topic

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

Description

VDSM is a management module that serves as a Red Hat Virtualization Manager agent on Red Hat Virtualization Hosts (RHVH) or Red Hat Enterprise Linux hosts.

Changes to the vdsm component:

• Previously, the partition number was not removed from the disk path, so the disk mapping pointed to an arbitrary partition on the disk, instead of the disk itself. The current release fixes this issue: Disk mapping contains only disk paths. (BZ#1793290)
• Previously, virtual machine (VM) imports from sparse storage assumed the target also used sparse storage. However, block storage does not support sparse allocation. The current release fixes this issue: Imports to block storage for COW image file formats preserve sparse allocation types and work as expected. (BZ#1663135)
• Before this update, when you ran a VM that was previously powered off, the VDSM log contained many uninformative warnings. This update resolves the issue and these warnings no longer appear in the VDSM log. (BZ#1740058)

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
