RHBA-2019:3009 - Bug Fix 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 Virtualization Manager agent on Red Hat Virtualization Hosts or Red Hat Enterprise Linux hosts.

Changes to the vdsm component:

• Previously, v2v was reporting the wrong disk type when using the -o rhv and -o vdsm option; copying disks created by virt-v2v failed with: InvalidParameterException: Invalid parameter: 'DiskType=1'. Although the issue of assigning the wrong disk type was fixed in virt-v2v upstream, we must be able to copy disks created using the "broken" version of virt-v2v. The current release enables us to do this by adding support for that incorrect disk type, "1". (BZ#1748395)
• Previously, trying to enable virtual functions (VFs) on a Broadcom network card generated a "Failed to change the number of virtual functions" error. The current release fixes this issue. (BZ#1691760)
• The current release rebuilds Red Hat Virtualization (4.3.6) for the current version of Red Hat Enterprise Linux 7. (BZ#1734619)
• Previously, while VDSM service was starting, the nwfilter configuration removed and recreated the 'vdsm-no-mac-spoofing' network filter definition to ensure the filter was up to date. If many vNICs were using the filter, that operation took longer than expected and caused the VDSM startup to timeout. The current release fixes this issue by updating the filter, which takes less than a second independent of how many vNICs are using the filter. (BZ#1740498)
• Previously, while powering off a virtual machine, the RHV Manager occasionally displayed an error message that the VDSM Get Host Statistics command failed due to an Internal JSON-RPC error: {'reason': '[Errno 19] vnet111 is not present in the system'}. This error occurred because an interface disappeared while the host statistics were being gathered. The current release fixes this issue by suppressing this error under these conditions. (BZ#1744572)
• Previously, some virtual machine operations unnecessarily blocked other VM operations. This led to some problems with monitoring while shutting down large virtual machines. The current release fixes these issues: It relaxes some conditions for blocking virtual machine operations and makes blocking safer. This should reduce monitoring problems experienced in some scenarios. (BZ#1660451)
• vdsm now requires a host kernel with fix for CVE-2019-14835 (BZ#1753116)
• Previously, the gluster fencing policy check failed due to a non-iterable object and threw an exception. The code also contained a minor typo. The current release fixes these issues. (BZ#1746718)
