Chapter 2. RHEA-2017:1114 Red Hat Virtualization Host 4.1 GA Enhancement

imgbased

BZ#1364040

Previously, the Red Hat Virtualization Host (RHVH) may have repeatedly prompted for upgrades, even when running the most recent version. This was caused by a placeholder package in the  image, which was made obsolete in order to perform the upgrade. However, the package that was used to upgrade was not propagated to the the RPM database on the new image.
This release now includes the missing update package in the RPM database on the new image, when upgrading the RHVH.

BZ#1432385

Previously, running imgbase layout took a very long time to complete on Red Hat Virtualization Hosts (RHVH) that had a very large number of LUNs or other LVM devices attached, due to the fact that it did not filter LVM commands with known tags. In this release, the LVM devices are filtered, which dramatically improves the performance for systems with a large number of LUNs.

ovirt-node-ng

BZ#1380797

Previously, a bug might have enabled services that were disabled when upgrading Red Hat  Virtualization Host (RHVH). With this update, the bug was fixed. As a result, when upgrading RHVH, disabled services remain disabled.

BZ#1382833

Previously, the crond service was not enabled in the default configuration of Red Hat Virtualization Host (RHVH) 4.x. As a result, the log rotation functionality was not triggered, resulting in very large log files which could potentially fill the disk. In this release, the bug was fixed. As a result, the crond service is now enabled in the default configuration and log rotation functions as required.

BZ#1382843

With this update, the Red Hat Virtulaization Host includes sysstat as part of the base image.

BZ#1389324

Previously, the 'Networking' tab in Cockpit was disabled in Red Hat Virtualization Host (RHVH) images. This is now enabled, meaning that system networking can be configured through Cockpit in RHVH.

BZ#1417534

Previously, imgbased copied /etc from old layers into new layers in order to keep configuration changes between upgrades. This behavior differed from that of RPM, in that unmodified configuration files would be preserved across imgbased upgrades rather than being replaced.

In this release, imgbased  compares the sums of files to the originals that are kept per-layer in /usr/share/factory/etc. As a result, the unmodified configuration files are now handled as required.

BZ#1436172

Previously, imgbased did not add groups that were present on the new image but not the old one. As a result, systemd-tmpfiles-clean.service failed. In this release, imgbased adds groups from new layers and systemd-tmpfiles-clean.service is functioning properly.

BZ#1422024

With this release, the net-snmp package is part of the Red Hat Virtualization Host image by default.

BZ#1432359

Previously, Anaconda created a small metadata logical volume that was smaller than . As a result, the logical volume could reach 100% capacity. In this release, during upgrades, if the metadata logical volume is less than 1 GB, it is resized to 1 GB.

BZ#1379763

The "screen" package is now available as part of the base RHVH image.

rhev-hypervisor-ng

BZ#1364978

Previously, Red Hat Virtualization Host (RHVH) was shipped without an End User License Agreement (EULA). In this release, this bug has been fixed and RHVH now includes an EULA.

BZ#1419483

Previously, Red Hat Virtualization Host (RHVH) was shipped with a for version 4.0 certificate and as a result 4.0 appeared in the Subscription page instead of 4.1. In this release, the correct certificate has been shipped, and RHVH now displays 4.1 in the Subscription page.

BZ#1422743

Previously, Red Hat Virtualization Host (RHVH) placed several requisite files (initrd, kernel) in a subdirectory under /boot. As a result, some system utilities, including kdump, were unable to locate the files in the subdirectory, regardless of the BOOT_IMAGE settings.
In this release, the boot files are copied to /boot on startup and kdump is functioning properly.

BZ#1429288

Previously, VDSM was not configured after upgrading Red Hat Virtualization Host (RHVH). As a result RHVH could not run together with a Manager that was running an earlier version. In this release, by running  vdsm-tool configure --force on boot, the VDSM is configured successfully.
