It's not necessary to have the dcagent keystone user present on system controller. Its presence can cause problems during upgrade as it would be necessary for the dcagent user in the subcloud to have the same password as system controller upon creation (before dcdbsync synching upon managing the subcloud). Test plan: - PASS: Build a developer ISO. Deploy a DC system with 2 system controllers and 1 subcloud. Verify the dcagent user is created only on the subcloud. - PASS: Manage the subcloud and verify the dcagent service is working as expected. - PASS: Perform a network reconfiguration on the subcloud. Verify the operation finishes successfully. Story: 2011106 Task: 50747 Change-Id: I13deb83f2e8b602fd8d733b999cf579d4db05034 Signed-off-by: Victor Romano <victor.gluzromano@windriver.com>
