Public bug reported: I have created a base VM (to install rdo queens) with RHEL 7.4 OS, 16 GB RAM, 8 CPU,200 GB HDD, virtualization enabled.
I have installed RDO queens (all-in-one topology) using command below : nohup packstack --allinone --provision-demo=n --os-neutron-ovs-bridge-mappings=extnet:br-ex --os-neutron-ovs-bridge-interfaces=br-ex:ens192 --os-neutron-ml2-type-drivers=vxlan,flat,vlan --os-neutron-ml2-flat-networks=extnet --os-heat-install=y --keystone-admin-passwd=openstack1 & I wanted to configure flat network on this setup.So did below changes in ml2_conf.ini type_drivers = flat,vlan flat_networks = extnet changes in openvswitch_agent.ini : integration_bridge=br-int tenant_network_type = flat,vlan network_vlan_ranges = extnet enable_tunneling = True bridge_mappings = extent:br-ex physical_interface_mappings = extnet:br-ex Created security groups to allow ping/ssh to deployed instances: neutron security-group-rule-create --direction ingress --ethertype IPv4 --protocol tcp --port-range-min 22 --port-range-max 22 defualt neutron security-group-rule-create --direction ingress --ethertype IPv4 --protocol icmp default Created external n/w : neutron net-create external --router:external=True --shared --provider:network_type=flat --provider:physical_network=extnet neutron subnet-create --name ext-subnet external 172.16.82.0/24 --allocation-pool start=172.16.82.30,end=172.16.82.35 (dhcp=enabled) Deployed a cirros image on above created external n/w as admin user in default domain. I also made sure that security group rules created for tcp/icmp are applied while deployment. Note that : ifconfig command inside the deployed cirros instance displayed the IP from the allocation pool but IP can not ping the gateway, it can only ping the controller. I can not ping/ssh the IP assigned to deployed cirros instance from my machine. Note : If I disable the dhcp in subnet, ifconfig command does not display the IP for deployed instance. ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
