Network Manager, using static addressing. So no DHCP.

I assume you mean the kea dhcp4 server. Well, I see a lot of stuff.

I wasn't able to start it from the command line, even with su. So I
edited the service to add the -d. Searching on 'interface' I see:

Aug 27 16:41:28 hawk kea-dhcp4[29687]: DEBUG DHCP4_CONFIG_RECEIVED
received configuration { … "interfaces-config": { "interfaces": [
"enp3s0/192.168.100.6" ] }, … .
…
Aug 27 16:41:28 hawk kea-dhcp4[29687]: INFO  DHCPSRV_CFGMGR_USE_ADDRESS
listening on address 192.168.100.6, on interface enp3s0

and that's it. It doesn't appear to claim any others, probably because
I shut down the virtual network. But the virtual network refuses to
start.

I ran 'journalctl -f', and tried to start up the virtual network.
Nothing in the trace indicating that kea tried to grab the virtual
interface.

The network's definition has the following:

  <dnsmasq:options>
    <dnsmasq:option value="interface=virbr0"/>
    <dnsmasq:option value="except-interface=lo,enp3s0"/>
  </dnsmasq:options>

If I don't get any satisfaction here I will try those two.
