Note that support for Skylake-Server is already in oVirt 4.2.2, once you’re running on a hypervisor which supports that(e.g. RHEL 7.5 beta) it should work, when you run on the exsiting 7.4 it just won’t work (the option is there though, and we separated the generic former “Skylake” to Skylake-Client and Skylake-Server)
