Procedure

1. Enable the Red Hat Virtualization Manager 4.2, Red Hat Virtualization Tools, and Ansible Engine repositories:

   # subscription-manager repos --enable=rhel-7-server-rhv-4.2-manager-rpms
   # subscription-manager repos --enable=rhel-7-server-rhv-4-manager-tools-rpms
   # subscription-manager repos --enable=rhel-7-server-ansible-2-rpms

   Important

   Red Hat Virtualization Manager 4.2 requires Red Hat JBoss Enterprise Application Platform (JBoss EAP) 7.1 to be installed on the Manager machine. Ensure that the jb-eap-7-for-rhel-7-server-rpms repository is enabled, and that the jb-eap-7.0-for-rhel-7-server-rpms repository is disabled. Run subscription-manager repos --list to check which repositories are enabled.

2. Update the setup packages:

   # yum update ovirt\*setup\*

3. Run engine-setup and follow the prompts to upgrade the Red Hat Virtualization Manager:

   # engine-setup

4. Remove or disable the Red Hat Virtualization Manager 4.1 repositories to ensure the system does not use any 4.1 packages:

   # subscription-manager repos --disable=rhel-7-server-rhv-4.1-rpms
   # subscription-manager repos --disable=rhel-7-server-rhv-4.1-manager-rpms
   # subscription-manager repos --disable=rhel-7-server-rhv-4-tools-rpms

5. Update the base operating system:

   # yum update

   Important

   If any kernel packages were updated, reboot the system to complete the update.

6. If Data Warehouse is installed on a separate machine, log in to that machine and restart the ovirt-engine-dwhd service:

   # systemctl restart ovirt-engine-dwhd
