# start openvswitch on both controller-0 and compute-0
systemctl start openvswitch

make /etc/hosts blank in controller-0 and compute-0
otherwise ansible-ssh-config step will fail

set controller-0 and compute-0 hostnames to contrroler-0 and compute-0 (don't add any domain), otherwise ansible--shc-onfig generation will fail


Must set netmask to unique ip address like https://github.com/venkataanil/osp_templates/blob/master/deployed_servers/uc/virt/network/saravanan_netmask_file
otherwise u have to manullay add unique netwmasks in below files
tripleo-config/ControllerDeployedServer/compute-0/NetworkDeployment and tripleo-config/ControllerDeployedServer/controller-0/NetworkDeployment, in both of them ip_netmask for InternalApiIpSubnet and for any other subnets shouldn't be null. Update them to proper values for example "172.17.1.9/24". It has to be a string.
If not then update tripleo-config/ControllerDeployedServer/compute-0/NetworkDeployment from tripleo-config/ControllerDeployedServer/compute-0/ControllerDeployedServerDeployment. Same with compute
Also add undercloud's dns_servers(/etc/resolv.conf) to compute and controllers tripleo-config/ControllerDeployedServer/compute-0/NetworkDeployment dns-servers field

Add vlan interfaces on undercloud as well, I think this is not needed
[stack@undercloud-0 ~]$ sudo ovs-vsctl add-br br-ex
[stack@undercloud-0 ~]$ sudo ovs-vsctl add-port br-ex eth2
[stack@undercloud-0 ~]$ sudo ovs-vsctl add-port br-ex vlan10 tag=10 -- set interface vlan10 type=internal
[stack@undercloud-0 ~]$ ip a a 10.0.0.104/24 brd 10.0.0.255 dev vlan10 
RTNETLINK answers: Operation not permitted
[stack@undercloud-0 ~]$ sudo ip a a 10.0.0.104/24 brd 10.0.0.255 dev vlan10 
[stack@undercloud-0 ~]$ sudo ip l set vlan10 up

Debugging tips:
If you want to download and replly netconfig, remove this file in controller node
sudo rm -f /var/lib/heat-config/deployed/43ef6dd9-396a-42e9-adbb-65a2946cea7b.json

Some other config files for debugging
