RHV: How to manually upgrade RHEL 8 Host to 8.3

Environment

• Red Hat Virtualization 4.4.2
  • Red Hat Enterprise Linux Host 8.2

Issue

• How to upgrade RHEL 8.2 Host to RHEL 8.3 Host

Resolution

• Note the recommended way of upgrading is via the Administration Portal, please see Upgrade Guide -
  Updating Individual Hosts. Manual upgrades lack additional operations done by RHV-M and may produce problems.

Enable the 8.3 Stream for Advanced Virtualization, and then upgrade manually:

1. Ensure the correct repositories are enabled. You can check which repositories are currently enabled by running dnf repolist.

# subscription-manager repos \
    --enable=rhel-8-for-x86_64-baseos-rpms \
    --enable=rhel-8-for-x86_64-appstream-rpms \
    --enable=rhv-4-mgmt-agent-for-rhel-8-x86_64-rpms \
    --enable=ansible-2.9-for-rhel-8-x86_64-rpms \
    --enable=advanced-virt-for-rhel-8-x86_64-rpms \
    --enable=fast-datapath-for-rhel-8-x86_64-rpms

2. In the Administration Portal, click Compute → Hosts and select the host to be updated.
3. Click Management → Maintenance.
4. Update the host:

# dnf module reset virt -y; dnf module enable virt:8.3 -y
# dnf upgrade

5. Reboot the host to ensure all updates are correctly applied.

Root Cause

• The documentation does not contain steps about the switch of the Advanced Virtualization Stream to 8.3
• The documentation update is being tracked in This content is not included.Bug 1886721 - "Manually Updating Hosts" document is not working for updating RHEL-AV.

Diagnostic Steps

The Advanced Virt module is still set to the 8.2 Stream
