Yeah, I agree. Start as small as possible and move to more machines
from there if it doesn't solve the issues.
OK. I will use this for Copr machines only for now.

Yeah, I think neutron does use gre tunnels... but I am not fully clear
how.
Yes, it use GRE:
$ grep CONFIG_NEUTRON_OVS_TENANT_NETWORK_TYPE
./files/fedora-cloud/pakstack-controller-answers.txt
CONFIG_NEUTRON_OVS_TENANT_NETWORK_TYPE=gre
# grep tenant_network_types /etc/neutron/plugin.ini
tenant_network_types = gre
