I'm mostly sure that if you want to run dhcpd, you just need to turn off the "default" network and use bridged networking instead. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/5/html/Virtualization/sect-Virtualization-Network_Configuration-Bridged_networking_with_libvirt.html (Hasn't really changed) Under virt-manager, connect to the local host, then right-click on the local host and open "Details." Switch to the Virtual Networks tab, and uncheck the Autostart: On Boot option. Guests will get dhcp from the bridged network, and will be on the same broadcast domain as the KVM host.
