Hi,

After rebasing to latest master, fedora 26, I can't run engine setup on a fresh engine root and empty database if I select 'yes' for ovn setup:

Please note we are not committed to support Fedora 26 for 4.2/master

I suspected 596c3fb
packaging: Require OVN
    
    Make the engine require OVN pacakges, as setup defaults to configuring
    it.
    
    Make setup require the OVN packages that provide firewalld services, so
    that engine-setup can have their content during customization stage.

Moving to 596c3fb gives the same error. Moving to 596c3fb^1 (51d474d engine: update vdc_option values) gives a different error:

[ INFO  ] Stage: Environment customization

          Install and configure ovirt-provider-ovn? Please note that this will cause an immediate installation

[ INFO  ] Generating answer file '/home/greg/ovirt-engine/var/lib/ovirt-engine/setup/answers/20170928095333-setup.conf'


And there I gave up. Selecting "no" to ovn setup allows setup to succeed.

Anyone know if I need to update something, or is this a bug?

Best wishes,
Greg
