    Installing Openstack (conjure-up) on Ubuntu

The guide explains how to install OpenStack on available resource and make VMs available for medium and large-scale projects. OpenStack is deployed using Ubuntu Conjure-up charm on single workstation.
Hardware Available


2 x Intel Xeon(R) CPU E5-2620 - 2.4 GHz
128 GB RAM
2 x 1000 Mbps LAN port
2 TB Storage with RAID

Software Requirement


Ubuntu 14.04 LTS

Network Configuration

Subnet Available

CIDR : 172.16.18.0/ 23
Default Gateway : 172.16.19.254
Broadcast Domain : 172.16.19.255
DNS Server : 172.16.2.34
Static Ip range : 172.16.18.1 - 172.16.18.25
IP range for Neutron DHCP - 172.16.18.14 - 172.16.18.24

Network configuration

Current machine has two network interfaces - eth0 and eth1. Hence we assign two static IPs two each of them namely - 172.16.18.11 and 172.16.18.12
eth0*


Add following to /etc/network/interfaces file to make static ip on eth0

auto eth0
iface eth0 inet static
address 172.16.18.11
netmask 255.255.254.0
network 172.16.18.0
gateway 172.16.19.254
dns-nameserver 172.16.2.34

eth1**


Add following to /etc/network/interfaces file to make static ip on eth1

auto eth1
iface eth1 inet static
address 172.16.18.12
netmask 255.255.254.0
network 172.16.18.0
gateway 172.16.19.254
dns-nameserver 172.16.2.34

Installation Procedure

1. Installlling conjure-up

$ sudo apt-get install snapd
$ sudo groupadd lxd && sudo usermod -a -G lxd $USER
$ sudo reboot
$ sudo snap install conjure-up --classic

2. Conjuring Openstack

$ conjure-up


On terminal GUI press Tab and Enter to  Select install Openstack using LXD
Set the name of the implementation
Deploy all the systems
Download all the glance images
Set up the SSH key
Set up neutron
Set up horizon dashboard


3. Restart network

$ sudo service networking restart
$ sudo service network-manager restart

4. If  eth0 and eth1 interfaces are down


Copy the eth0 and eth1 interface details from (*) and (**)

$ sudo service networking restart
$ sudo service network-manager restart
$ sudo ifdown eth0
$ sudo ifdown eth1
$ sudo ifup eth0
$ sudo ifup eth1

5. Alter the conjureup0 bridge details


Add following to /etc/network/interfaces file.

auto conjureup0
iface conjureup0 inet static
        address 172.16.18.11
        network 172.16.18.0
        netmask 255.255.254.0
        broadcast 172.16.19.255
        gateway 172.16.19.254
        dns-nameservers 8.8.8.8
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
        bridge_maxwait 0


Then restart the network

$ sudo service networking restart
$ sudo service network-manager restart
$ sudo ifdown eth0
$ sudo ifdown eth1
$ sudo ifup eth0
$ sudo ifup eth1
$ sudo ifdown conjureup0
$ sudo ifup conjureup0

6. To access horizon dashboard accross the network


As horizon dashboard is accessible at 10.0.8.245 add /etc/hosts file

10.0.8.245	localhost


Forwarding the requests from external network to access horizon dashboard via iptables command

$ sudo iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80
 -j DNAT --to-destination 10.0.8.245:80

7. Log into horizon dashbaord to configure network


Log on to horizzon dashbaord at 172.16.18.12/horizon or localhost/horizon(if on same system) using u: admin and p: openstack
Delete all the previous network, subnets and routers
Click on create new network on networks tab named ext-net
Select local for Provider Network Type and make the network external network
Add subnet with network configuration above Subnet Available
Now create a new network local and add a sub-net with 10.X.X.X/24 ip.
Create a net router and interface it with both 'ext-net' and 'local'.


8. Launching VM


While launching VM make sure that the VM are launched on local or equivalent internal network and then floating ip from ext-net is assgined.
