The demo server at ON.LAB (IP address 10.254.1.22, login: admin) currently runs XOS, the OpenStack controller services, and a nova-compute node in a VM. For the demo it is also intended to run two ONOS instances but these have not been configured yet.

Each service runs in its own KVM virtual machine. Use virsh list to see a list of the running VMs, each named after the service it hosts:
admin@cordsrv01:~$ virsh list Id Name State---------------------------------------------------- 2 xos running 3 juju running 4 mysql running 5 rabbitmq-server running 6 keystone running 7 glance running 8 nova-cloud-controller running 9 quantum-gateway running 10 openstack-dashboard running 11 ceilometer running 12 nagios running
16 xos running 23 compute-1 running
All of the VMs are attached to bridge virbr0 with private addresses on the 192.168.122.0/24 subnet, and so are not reachable externally. The IP addresses of the VMs are in /etc/hosts, or can be obtained using uvt-kvm ip <VM name>:
admin@cordsrv01:~$ uvt-kvm ip xos
192.168.122.37
Log in to a VM using ssh ubuntu@<VM name>. The default SSH key for the admin user (/home/admin/.ssh/id_rsa.pub) has been added for the ubuntu user inside all the VMs, so this should just work:
admin@cordsrv01:~$ ssh ubuntu@compute-1
Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-49-generic x86_64)
...
ubuntu@compute-1:~$
The existing VMs are created using the uvt-kvm tool. To create a new VM (e.g., for ONOS) run uvt-kvm <VM name> --cpu=<num vCPUs> --memory=<memory MB> --disk=<disk GB>. Be aware that this server has a small disk, though plenty of memory and CPU cores.
The XOS GUI is at http://10.254.1.22:8000. Contact Scott Baker or Andy Bavier for login credentials.
The changes to support vCPE creation are not yet installed in XOS. Information on the vCPE service interface will be added soon.
OpenStack services run in their own VMs. Juju is used to install the services. One feature of Juju is that it generates the OpenStack configuration files automatically – this means that all changes to the OpenStack configuration need to be implemented via Juju, or else they will be overwritten. Contact Andy Bavier to discuss this.
Admin credentials for OpenStack can be found in /home/admin/admin-openrc.sh on the server. The various OpenStack clients are installed and can be run with these credentials. E.g.:
admin@cordsrv01:~$ source admin-openrc.shadmin@cordsrv01:~$ nova service-list+----------------+-----------------------+----------+---------+-------+----------------------------+-----------------+| Binary | Host | Zone | Status | State | Updated_at | Disabled Reason |+----------------+-----------------------+----------+---------+-------+----------------------------+-----------------+| nova-scheduler | nova-cloud-controller | internal | enabled | up | 2015-04-17T19:29:34.000000 | - || nova-cert | nova-cloud-controller | internal | enabled | up | 2015-04-17T19:29:36.000000 | - || nova-conductor | nova-cloud-controller | internal | enabled | up | 2015-04-17T19:29:40.000000 | - || nova-compute | compute-1 | nova | enabled | up | 2015-04-17T19:29:43.000000 | - |+----------------+-----------------------+----------+---------+-------+----------------------------+-----------------+
The installation is automated using Ansible so it's easy to tear down and recreate the OpenStack installation if required. Talk to Andy Bavier about this.
The CMI is running in a VM on the demo headnode. The XML defining the VM is at /etc/libvirt/qemu/cmi.xml. The image is in /var/lib/libvirt/images/cmi.qcow.
The CMI makes use of the following port forwarding rules:
iptables -t nat -I PREROUTING -p tcp --dport 8003 -j DNAT --to-destination 192.168.122.217:8003
iptables -t nat -I PREROUTING -p tcp --dport 8004 -j DNAT --to-destination 192.168.122.217:8004
iptables -t nat -I PREROUTING -p tcp --dport 8140 -j DNAT --to-destination 192.168.122.217:8140
iptables -t nat -I PREROUTING -p tcp --dport 1022 -j DNAT --to-destination 192.168.122.217:1022
iptables -I FORWARD -p tcp --dport 8003 -j ACCEPT
iptables -I FORWARD -p tcp --dport 8004 -j ACCEPT
iptables -I FORWARD -p tcp --dport 8140 -j ACCEPT
iptables -I FORWARD -p tcp --dport 1022 -j ACCEPT
The following should be added to the /etc/hosts on each physical machine

The following should be added to the /etc/hosts on the demo headnode:
