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?

Hm... 'ip a a s' is not working. Do you mean 'ip addr'?
root@vm02-fai:/home/thomas# ip a a s
Error: inet prefix is expected rather than "s".
