Title:
Unable to ssh/ping IP assigned to VM deployed on flat network
Status in neutron:
Expired
Bug description:
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.
