- Trying to configure Eth1 (FLAT) network on VIRL server but each time we change the IP address, the Eth0 IP address goes back to 127.0.0.1 without any reason (server become unavailable, we had to go in console to manually reconfigure the /etc/network/interface file and reconfigure Eth0, then reload).
- We did the modification using the GUI (UWM).
- After changing the Eth0 back to its normal IP, we can't launch any simulation because the system just say "Failed to start simulation: Openstack call to Network2_0.create_ports received invalid response status 409 (Confilct) with error "IpAddressGenerationFailure: No more IP addresses available on network 6fb8831a-5f6a-45b3-a6da-b4a2d1d74048"
- Why is it mandatory to configure a DHCP pool range in this FLAT network. Disabled the service using command "neutron subnet-update --disable-dhcp flat1", but it should be disabled by default.
