All rights reserved. 5 VMware Setup These instructions are based on VMware Fusion 7.1.1 Pro, but should apply to other versions of VMware Fusion (Mac) and VMware Workstation (PC). VMware configuration and enablement If you haven’t already done so, download and install VMware Fusion. By default VMware will configure two networks: 1. Shared with my Mac (or PC) (Effectively NAT Overload on the laptop IP) 2. Private to my Mac (Internal L2 segment with no default routing capabilities). There is only a need to have a single interface, specifically the “Shared with my Mac” {or on a PC} NAT network, this being the default NAT network It is necessary to ensure that the Shared with my Mac adapter has the same address as the VM being deployed in order for the VM to function properly. To change the address on a Mac, pull up a terminal window and edit the VMware Fusion network definition file: sudo nano /Library/Preferences/VMware Fusion/networking The file should have a set of VNET_8 clauses that looks like (there may be more config lines as well, but these are the critical ones): •answer VNET_8_DHCP yes •answer VNET_8_HOSTONLY_NETMASK 255.255.255.0 •answer VNET_8_HOSTONLY_SUBNET 192.168.56.0 •answer VNET_8_VIRTUAL_ADAPTER yes •answer VNET_8_NAT yes To change the address on a PC, changing the network address for the “NAT” interface can be done via the User Interface:

All rights reserved. 7 VirtualBox Setup If you do not have VirtualBox installed, the software components have been provided for your convenience in the VirtualBox Installation directory. Note that in addition to the installer itself (.exe, .dmg, .rpm or .deb), there is an extension pack that should be installed after the base VirtualBox platform is installed, but prior to starting any virtual machines. Additional information is available at: http://virtualbox.org. Virtualbox configuration and enablement If you haven’t already, leverage the appropriate installer on the USB stick, and install Virtual Box, followed by the Virtual Box extension pack. For this system, you will need to associate 2 networks with your imported OVA (the next step is to import the OVA): Adapter 1: HostOnly network with or with DHCP with a base address space of 192.168.56.0/24, and if DHCP is enabled the range should start above 20 (e.g. 192.168.56.20-‐192.168.56.100). Adapter 2: NAT network, this being the default NAT network If you don’t have host only networks defined, or the networks you have do not match the addresses listed above, you can create new networks from the systems level preferences. On a Mac, you should see screen shots like this:

All rights reserved. 9 Overall Objectives The lab will be segmented into logical tasks, each having several steps to be completed to help you become familiar with DevStack installation and usage. 1. Task 1 – Bring up Ubuntu VM 2. Task 2 – Install DevStack from stable Kilo branch 3. Task 3 – Bring up DevStack Horizon 4. Task 4 – Configure demo tenant network 5. Task 5 – Configure demo tenant router 6. Task 6 – Configure demo tenant instance 7. Task 7 – Add access rules to allow ping/ssh to instance 8. Task 8 – Add floating IP to instance 9. Task 8 – Much fanfare and hoopla

10. CiscoLive 2015 © Cisco and/or its affiliates. All rights reserved. 10 Task 1 – Bring up Ubuntu VM Prerequisite: Have either VirtualBox or VMware Fusion installed on laptop 1. On the USB stick, locate the Ubuntu 14.04.2 image for either VirtualBox or VMware Fusion, depending on your configuration: USB -‐> CiscoLive -‐> Ubuntu-‐14.04 -‐> [VMware or VirtualBox] 2. Import the Ubuntu OVA file into Fusion or VirtualBox 3. Start the Ubuntu VM

12. CiscoLive 2015 © Cisco and/or its affiliates. All rights reserved. 12 Task 2 – Install DevStack from stable Kilo branch 1. Bring up Terminal window in Ubuntu VM 2. cd /home/demo/CiscoLive 3. edit (vi or emacs) localrc, comment out this line: # Logging LOGFILE=$DEST/logs/stack.sh.log VERBOSE=True #OFFLINE=True ßadd # in front of this line LOG_COLOR=False SCREEN_LOGDIR=$DEST/logs/screen 4. cd /home/demo 5. git clone –b stable/kilo https://github.com/openstack-‐dev/devstack.git 6. cp /home/demo/CiscoLive/localrc /home/demo/devstack 7. cd /home/demo/devstack 8. ./stack.sh 9. Get a cup of coffee, make a few phone calls ….
