I am deploying juno on ubuntu server 14.04 cluster in virtual box.

Right now all nova, neutron, and other needed services are running.

The Network Configuration is as specified here http://docs.openstack.org/icehouse/training-guides/content/building-training-cluster.html (http://docs.openstack.org/icehouse/tr...) with a little variant since Im using other private networks.

My network interface on each node are:

#Controller Node

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface - NAT connection
auto eth0
iface eth0 inet dhcp

# vboxnet0 - OpenStack management network
auto eth1
iface eth1 inet static
address 10.0.0.11
netmask 255.255.255.0

# vboxnet2 - OpenStack API network
auto eth2
iface eth2 inet static
address 203.0.113.11
netmask 255.255.255.0

#Network Node # The loopback network interface auto lo iface lo inet loopback

# The primary network interface - NAT network
auto eth0
iface eth0 inet dhcp

# vboxnet0 - OpenStack management network
auto eth1
iface eth1 inet static
address 10.0.0.21
netmask 255.255.255.0

# vboxnet2 - OpenStack data/communication network
auto eth2
iface eth2 inet static
address 10.0.1.21
netmask 255.255.255.0

#vboxnet3 - For exposing external network
auto eth3
iface eth3 inet manual
up ifconfig $IFACE 0.0.0.0 up
up ip link set $IFACE promisc on
down ip link set $IFACE promisc off
down ifconfig $IFACE down

#For giving access to network node via the external network
auto br-ex 
iface br-ex inet static
address 203.0.113.21
netmask 255.255.255.0

#Compute Node # The loopback network interface auto lo iface lo inet loopback

# The primary network interface - NAT connection
auto eth0
iface eth0 inet dhcp

# vboxnet0 - OpenStack management network
auto eth1
iface eth1 inet static
address 10.0.0.31
netmask 255.255.255.0

# vboxnet2 - OpenStack VM data/communication network
auto eth2
iface eth2 inet static
address 10.0.1.31
netmask 255.255.255.0

All nodes can ping each other.

The host only networks are configured as follows:

vboxnet0 = 10.0.0.1 (255.255.255.0)
vboxnet1 = 10.0.1.1 (255.255.255.0)
vboxnet2 = 203.0.113.1 (255.255.255.0)

There is an instance active, running with a floatin ip associated:
