I just noticed when HCI setup bult the gluster engine / data / vmstore volumes... it did use correctly the definition of 10Gb "back end" interfaces / hosts.   

But..  oVirt Engine is NOT referencing this.
it lists bricks as 1Gb "managment / host" interfaces.  Is this a GUI issue?  I doubt this and how do I correct it?
