Created a VM instance - This was successful. Assigned a floating IP also. Can see the console of the instantiated VM.

I cannot seem to hit the VM from my laptop, or on nodes other than the network node. Not sure what to do next in terms of troubleshooting. I can ssh and ping from the network node, but not compute, or control.

IP Spaces -

10.21.200.x - Control, Network, Compute Node locations

ens192 - network nic that connects to physical connection this is assigned for example 10.21.200.4 for control .5 for network .6 for compute

ens224 - internal network nic

192.168.11.x - Private network subnet - That I created in neutron

The following is the config from packstack answer file:

CONFIG_NEUTRON_L3_EXT_BRIDGE=provider    
CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vxlan,flat    
CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=vxlan    
CONFIG_NEUTRON_ML2_MECHANISM_DRIVERS=openvswitch    
CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=extnet:br-ex    
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:ens192    
CONFIG_NEUTRON_OVS_BRIDGES_COMPUTE=    
CONFIG_NEUTRON_OVS_EXTERNAL_PHYSNET=extnet    
CONFIG_NEUTRON_OVS_TUNNEL_IF=ens224    
CONFIG_NEUTRON_OVS_TUNNEL_SUBNETS=    
CONFIG_NEUTRON_OVS_VXLAN_UDP_PORT=4789    
CONFIG_PROVISION_OVS_BRIDGE=y

ALso when configuring the public and private networks -

neutron net-create public --provider:network_type flat --provider:physical_network extnet --router:external

neutron subnet-create --gateway 10.21.200.1 --allocation-pool start=10.21.200.35,end=10.21.200.50 --disable-dhcp --name public_subnet public 
10.21.200.0/24

neutron  subnet-create private 192.168.11.0/24 --name private_subnet  --enable-dhcp=True --dns-nameserver 8.8.8.8 --dns-nameserver 8.8.4.4
