Guest OS is Debian 9 with this network configuration: thomas@vm02-fai:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5).

# The loopback network interface auto lo iface lo inet loopback

So, to answer your question: yes, 1st interface is doing DHCP.
Well, this doesn't prove it. ens3 might actually be the one that's connected to the 'internal' network. What's the output of 'ip a a s' ran from within the guest? What's the output of 'virsh domifaddr --source agent $domain'? BTW: if you sniff on virbr0 while the domain is starting up do you see any DHCP traffic? Michal
