   3 ## Installing OpenStack via Vagrant on Fedora 17 using https://github.com/lorin/openstack-ansible
   4
   5 The great thing about this repo is that it "just works" from Fedora 17 and quite possibly other platforms.
   6
   7 You'll be creating VMs within VMs, but don't worry about that. At the end of `make all` you'll have the following systems:
   8
   9 - **controller**: an Ubuntu box running the following OpenStack components
  10     - Nova: https://github.com/lorin/openstack-ansible/blob/master/playbooks/nova/controller.yaml
  11     - Glance: https://github.com/lorin/openstack-ansible/blob/master/playbooks/glance/setup.yaml
  12     - Keystone: https://github.com/lorin/openstack-ansible/blob/master/playbooks/keystone/setup.yaml
  13 - **compute1**: an Ubuntu box running the following OpenStack components
  14     - Nova: https://github.com/lorin/openstack-ansible/blob/master/playbooks/nova/compute-host.yaml
  15 - **instance-00000001**: a [CirrOS][] VM running on the **compute1** host
  16
  17 [CirrOS]: https://launchpad.net/cirros
  18
  19 ### Install dependencies
  20
  21 (You'll need to install [Vagrant][] and its dependencies, of course.)
  22
  23 [Vagrant]: http://vagrantup.com
  24
  25     yum install ansible
  26     yum install python-nova
  27
  28 (Fedora 17 ships with `python-nova-2012.1.3`)
  29
  30 ### `vagrant up` via `make all`
  31
  32     git clone https://github.com/lorin/openstack-ansible.git
  33     cd openstack-ansible
  34     make all
  35
  36 ### Verify that a "cirros" VM was created
  37
  38     source openrc
  39     nova list
  40
  41 You should see output similar to this:
  42
  43     +--------------------------------------+--------+--------+-----------------------+
  44     |                  ID                  |  Name  | Status |        Networks       |
  45     +--------------------------------------+--------+--------+-----------------------+
  46     | 8b10ed50-70a4-46a5-b69e-989cfe5b91a8 | cirros | ACTIVE | private=192.168.100.2 |
  47     +--------------------------------------+--------+--------+-----------------------+
  48
  49 ### Take a look at the two Openstack hosts that were created ("controller" and "compute1")
  50
  51     cd vms
  52     vagrant status
  53
  54 You should see output like this:
  55
  56     Current VM states:
  57
  58     controller               running
  59     compute1                 running
  60
  61 To ssh to compute1 (from the "vms" directory)
  62
  63     vagrant ssh compute1
  64
  65 Once you're ssh'd in, you can run a `virsh list`:
  66
  67     vagrant@compute1:~$ virsh list
  68      Id Name                 State
  69     ----------------------------------
  70       1 instance-00000001    running
  71
  72 Here's are the ethernet interfaces on the two Ubuntu hosts:
  73
  74 **controller**:
  75
  76     vagrant@controller:~$ ifconfig | grep 'inet addr' -B1

  88
  89 **compute1**:
  90
  91     vagrant@compute1:~$ ifconfig | grep 'inet addr' -B1
  92     br100     Link encap:Ethernet  HWaddr 08:00:27:d2:d2:9e

 107 I tried using a CentOS base box but the network config didn't work... the VMs didn't get the IP addresses from the Vagrantfile. Here is the error:
 108
 109     [controller] Configuring and enabling network interfaces...
 110     The following SSH command responded with a non-zero exit status.
 111     Vagrant assumes that this means the command failed!
 112
 113     /sbin/ifup eth1 2> /dev/null
 114
 115 Other users of CentOS base boxes report similar problems here: https://github.com/mitchellh/vagrant/issues/997
