Bug Fix(es):

  • The redhat-release-virtualization-host package no longer requires vdsm-hooks. In this release, the installation of vdsm-hooks is not mandatory for the Red Hat Virtualization Host. (BZ#1976095)

  • Previously, rhsmcertd was not enabled by default on the Red Hat Virtualization Host. As a result, the systems did not regularly report to RHSM while the subscription-manager reported no obvious issues and repositories were properly enabled.
    In this release, rhsmcertd is enabled by default in RHVH, and as a result, RHSM now receives reports regularly. (BZ#1958145)

  • In this release, the Red Hat Virtualization Host has been rebased on top of the RHEL 8.4.0 Batch #1 update. For more information, see the RHEL release notes. (BZ#1957242)

  • Red Hat Virtualization Host now includes an updated scap-security-guide-rhv which allows you to apply a PCI DSS security profile to the system during installation, (BZ#1883793)
