This is a basic verification scenario. It will eventually include three methods for verification:

• Horizon
• OpenStack CLI API
• OpenStack ReSTful API

In some cases a combination of these is necessary as noted below.

• https://blogs.oracle.com/ronen/entry/diving_into_openstack_network_architecture3
• http://docs.openstack.org/user-guide/dashboard_create_networks.html
• Bare-metal Multi-node single-NIC install using Foreman

1) On your test driver node browse to, and verify that these services are active:

• the Foreman UI at https://192.168.1.202 (login: admin/octopus)
• the Horizon UI at http://192.168.1.204 (login: admin/octopus)
• the DLUX UI at http://192.168.1.204:8181/dlux/index.html (login: admin/admin)

2) On controller, setup CLI environment for access to OpenStack APIs

• http://docs.openstack.org/user-guide/common/cli_set_environment_variables_using_openstack_rc.html
• Horizon: select Project / Access & Security / Download OpenStack RC File
• open the file and copy the contents to the clipboard
• SSH to the controller (root/Op3nStack) and create the API access resource file

[root@oscontroller1 ~]# vi admin-openrc.sh
# (paste admin-openrc.sh contents downloaded)
[root@oscontroller1 ~]# source  admin-openrc.sh

2) Create image cirros-0.3.3-x86_64

• Horizon: From Project / Compute / Images, select "Create Image". Set options Name "cirros-0.3.3-x86_64", Image Location "http://download.cirros-cloud.net/0.3.3/cirros-0.3.3-x86_64-disk.img", Format "QCOW2", Architecture "x86_64", (leave other options as-is or blank), and select "Create Image".
• CLI:

3) Verify that an external network and subnet exists (subnet "192.168.1.0/24", no DHCP) in Project / Network / Networks. For base-metal single-NIC non-HA install, you may need to create the external network via the CLI, if not already created as in Bare-metal Multi-node single-NIC install using Foreman.

• Horizon: apparently no current (Juno) option to designate a new network as "external". Have to do this via the CLI
• CLI:

[root@oscontroller1 ~]# neutron net-create external1 -- --router:external=true --provider:network_type=flat --provider:physical_network=physnet1
Created a new network:

• CLI:

6) Add internal network interface to the router.

• Horizon: From Project / Network / Routers, select router "external", and select "Add Interface". Select Subnet "internal", and select "Add Interface" (leave other options as-is or blank). Note: you may get disconnected fromt the Controller node for a short time
• CLI:

7) Launch images

• Horizon: From Project / Compute / Images, select "Launch" for image "cirros-0.3.3-x86_64". Select Name "cirros-1", network "internal", and "Launch". Leave other options as-is or blank. Repeat for instance "cirros-2".
• CLI:

8) Verify connectivity from VMs.

• Horizon: From Project / Compute / Instances, select "cirros-1" and "Console", and login with account "cirros" / "cubswin:)". Ping address of cirros-2 as shown in Horizon, 192.168.1.1 (external router), and opnfv.org (to validate DNS operation).
