Verify OpenStack and Floodlight Installation

Verify the Installation with nova and quantum commands:

Shown below is a snapshot of a session immediately after installing devstack:

~/quantum-restproxy$ source openrc demo demo
~/quantum-restproxy$ quantum net-list

~/quantum-restproxy$ quantum net-create net1
Created a new network:

~/quantum-restproxy$ quantum subnet-create 9c1cca24-3b7c-456d-afdd-55bc178b1c83 10.2.2.0/24
Created a new subnet:

~/devstack$ IMG_ID=`nova image-list | grep cirros | grep -v kernel | grep -v ram | awk -F "|" '{print $2}'`
~/devstack$ nova boot --image $IMG_ID --flavor 1 --nic net-id=9c1cca24-3b7c-456d-afdd-55bc178b1c83 vm1

~/devstack$ nova list

Creating Networks, Tenants, VMs

Now we have a working OpenStack server, we can launch a number of VMs on it and associate them with different virtual networks via the Quantum API.

odd_even_essex.sh creates two networks,each for two VMs.  If the nodes are created successfully, a number of tables will be printed, but make sure you WAIT PATIENTLY for the nodes to complete their boot process.  With four VMs nested inside a VM, the execution tends to be slow.  If you want to check whether the boot has completed, you can do, for example, 'sudo tail /opt/stack/nova/instances/instance-00000001/console.log' from time to time until you see the "CIRROS" welcom logo is printed at the end of the console log.

Note that pre-generated key pairs are specified in the script so that later logging into the created nodes does not need a password (with default username cirros).

odd_even_list_essex.sh lists all created networks and hosts by odd_even_essex.sh.

You can log into the OpenStack GUI by browsing the VM host-only adapter address (http://192.168.56.10x).  The login and password is as specified in odd_even_essex.sh (odd user/oddpass, even user/evenpass)

Ping Test

First, from the OpenStack server VM, ssh to one of the created VM

$ ssh cirros@10.4.4.2
(no password would be asked since we configured a key at installation time, and the key resides in .ssh/)
$ ping 10.4.4.3
(should work)
$ ping 10.5.5.2
(should still work, since the VMs have IP routing enabled)
$ sudo ifconfig eth0 netmask 255.0.0.0

In a second terminal on the OpenStack server VM, ssh to one of the created VM

$ ssh cirros@10.5.5.3
$ sudo ifconfig eth0 netmask 255.0.0.0
$ ping 10.4.4.2
(should not work -- Network Unreachable due to VNF)
$ ping 10.5.5.2
(should work - local network)
