If I try to setup hosted engine with the option to use Ansible it eventually fails on me.  See https://lists.ovirt.org/archives/list/users@ovirt.org/thread/LPK7OGFALSQFAN4UMEIHOION4BS2HJLN/

However if I run hosted-engine --deploy --noansible the setup does complete.  There is further trouble though,  it seems the networks are not being configured properly.  If I browse to Compute>Hosts>Hostname and click on the Setup Host Networks button I am presented with a new window that contains an unassigned logical network of "oivrtmgmt"   On the left side pane there are two columns for Interfaces and Assigned Logical Networks.  Both of those columns are completely empty.  I think if I understand correctly the interfaces column should at least have some info in it.

So my best guess is that for some unknown reason (at least to me) the Engine doesn't '"know how to get setup properly"  either with or without Ansible.  That's about as well as I can describe it.  I hope it makes sense....  Anyone have ideas on what is going wrong here?  Thanksfor any troubleshooting advice you can provide!
