[ovirt-users] nested virtualization and promiscuous mode

I want to run a VM, which will itself be the KVM host of a number of KVM guests. Each of the guests running in that nested environment will have a vNIC with an IP address on the same subnet as the top-level hypervisor (the ovirt node). In VMware vSphere environments I was able to do this by enabling promiscuous mode and forged transmits on the VMware distributed switch port group, as described in this medium article; https://williamlam.com/2013/11/why-is-promiscuous-mode-forged.html I've search a number of old threads here on the ovirt list archives. Many refer to vdsm hooks that don't appear to exist any longer in ovirt 4.5.1. How can I accomplish the same thing in ovirt?
