I believe the sharp edge is two DHCP servers on the same network. One DHCP server is the one that services your physical network, and the other DHCP server is the one for the virtual network. You don't want the two servers competing to serve addresses. You should use on DHCP server, and setup your VMs to get an address from the DHCP server on the physical network. That's easier said than done because libvirt docs don't provide instructions for the use case. Confer, <https://wiki.libvirt.org/VirtualNetworking.html>. I follow these instructions for setting up a bridge from the virtual network to the physical network, like <https://serverfault.com/q/1003855>. Jeff
