RHBA-2017:3431 - redhat-virtualization-host bug fix, and enhancement update for RHV 4.1.8

Synopsis

redhat-virtualization-host bug fix, and enhancement update for RHV 4.1.8

Type/Severity

Bug Fix Advisory None

Topic

Updated redhat-virtualization-host packages are now available.

Description

The ovirt-node-ng packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.

Changes to the imgbased component:

  • Previously, the self-hosted engine setup failed if the system clock was set to a time zone that was behind UTC during the installation. This is due to the fact that the Red Hat Virtualization Host generates VDSM certificates at the first boot and if the clock is incorrect, the chronyd or ntpd processes resynchronized the clock. This lead to an invalid certificate if the time zone was behind UTC.

Now, Red Hat Virtualization Host generates the certificates after the chronyd or ntpd processes, and waits two seconds for the clock to synchronize.

Note that if the Red Hat Virtualization Host is configured after the installation, or if the NTP server is too slow, the self-hosted engine setup may fail. (BZ#1455441)

Changes to the ovirt-host component:

  • The ipa-client package is now installed on hosts, and is included in the Red Hat Virtualization Host image. This enables Cockpit certificate signing and SSO with Red Hat IdM, and adding the host to an IdM realm. (BZ#1516194)

Changes to the ovirt-node-ng component:

  • Previously, RHVH migrated all files in /etc to /etc on new layers, with an attempt to catch files which were incorrectly removed. Network configuration files which were deleted in an intermediate layer were erroneously copied from older layers. Now, network configuration files are no longer remediated, so deleted network files no longer reappear. (BZ#1501047)
