OVE installation fails when cluster-managed networking is used. The installation eventually times out and transitions from installing-in-progress to error state.

1. Boot the Agent OVE ISO.
2. Make sure to select cluster-managed networking on the network page.
3. Wait for the error in the disconnected UI, it usually occurs after the process times out (about 1 hour).   

updated status from installing-in-progress to error (Host failed to install because its installation stage Waiting for control plane took longer than expected 1h0m0s) 

The installation should be successful

In the case of user-managed networking, it works fine. It appears there is a one hour condition that prevents installation when using cluster-managed networking, as real baremetal typically takes more than an hour to copy the ISO from virtual media to local storage.
The installation works when using dev-scripts because the VM takes less time to copy, since the ISO is already present locally in the libvirt environment.
