If an oVirt Engine implementation fails, the installation can be reversed using the utility: ovirt-hosted-engine-cleanup. The utility attempts to undo all tasks undertaken by the deployment script, though it warns the user it may not be able to do so. In addition, because of the reliance on a bridged network, the management network may go down. This is why it is essential to use the tmux interface which allows a reacquisition of the session if disconnected.
