IMS - Pre Migration for RHEL

This role sets up a Red Hat Enterprise Linux virtual machine for migration:

• It adds rules for network interface naming
• It installs the guest agent for oVirt / Red Hat Virtualization

Role Variables

You can change how this role works using some variables. By default, no variable is set, and the role assumes that RPM repositories are already configured on the host.

If the repositories are not set up yet, you can use the following variables to configure them. You can choose from three methods: RHN (Red Hat Satellite 5 / Spacewalk), RHSM (Red Hat Satellite 6 / Katello), or .repo files for local repositories.

• RHN - This method uses two variables:

  • rhn_config sets up the system to use Red Hat Satellite 5 / Spacewalk. It is a collection of key-value pairs for the rhn_register module.

  • rhn_channels specifies the software channels for the host. If you used an activation key with rhn_config, this may not be needed.

• RHSM - This method also uses two variables:

  • rhsm_config sets up the system to use Red Hat Satellite 6 / Katello. It is a collection of key-value pairs for the redhat_subscription module.

• Ad-hoc repositories - This method uses one variable:

  • yum_repositories is a list of collections, with each collection acting as a wrapper for the yum_repository module.

Example Playbook

The following playbook will register the virtual machine with a Satellite 6 server and enable the rhel-7-server-rpms repository. If no extra information is provided, the playbook will assume that the repositories are already set up and will try to install the agent.
