You will see subdirectories for different OS’s. “cd” into the OS that you want to test. centos6.48 is recommended as this is quicker to launch than other OS's.
Now you can start VMs with the following command:

cd centos6.48
cp ~/.vagrant.d/insecure_private_key .
./up.sh <# of VMs to launch>

For example, up.sh 3 starts 3 VMs. 3 seems to be a good number with 16GB of RAM without taxing the system too much.
With the default Vagrantfile, you can specify up to 10 (if your computer can handle it; you can even add more).
VMs will have the FQDN <os-code>[01-10].ambari.apache.org, where <os-code> is c59 (CentOS 5.9), c64 c68 (CentOS 6.48), etc.
E.g., c5901.ambari.apache.org, c6401c6801.ambari.apache.org, etc.
VMs will have the IP address 192.168.<os-subnet>.1[01-10], where <os-subnet> is 59 for CentOS 5.9, 64 68 for CentOS 6.48, etc.
E.g., 192.168.59.101, 192.168.64.101, etc.
Note that up.sh 3 command is equivalent to doing something like: vagrant up c640c680{1..3}

Testing Ambari

If it is your first time running a vagrant command, run:

...

Log into the VM:

vagrant ssh c6401c6801

Note that this logs you in as user vagrant. Once you are logged in, you can run:

...

Once Ambari Server is started, hit http://c6401c6801.ambari.apache.org:8080 (URL depends on the OS being tested) from your browser on your local computer.
Note that Ambari Server can take some time to fully come up and ready to accept connections. Keep hitting the URL until you get the login page.

Once you are at the login page, login with the default username admin and password admin.
On the Install Options page, use the FQDNs of the VMs. For example:

c6401c6801.ambari.apache.org
c6402c6802.ambari.apache.org
c6403c6803.ambari.apache.org

Alternatively, you can use a range expression:

c64c68[01-03].ambari.apache.org

...

vagrant up <vm name>
Starts a specific VM. up.sh is a wrapper for this call.
Note: if you don’t specify the <vm name> parameter, it will try to start 10 VMs
You can run this if you want to start more VMs after you already called up.sh
For example: vagrant up c6406c6806

vagrant destroy -f
Destroys all VMs launched from the current directory (deletes them from disk as well)
You can optionally specify a specific VM to destroy

...

vagrant ssh host
Starts a SSH session to the host. For example: vagrant ssh c6401c6801

vagrant status
Shows which VMs are running, suspended, etc.

...

This enables the “vagrant snapshot” command. Note that the above installs vesion 0.0.2. if you install the latest plugin version 0.0.3 does not allow taking snapshots of the whole cluster at the same time (you have to specify a VM name).
Run vagrant snapshot to see the syntax.
Note that the plugin tries to take a snapshot of all VMs configured in Vagrantfile. If you are always using 3 VMs, for example, you can comment out c64c68[04-10] in Vagrantfile so that the snapshot commands only operate on c64c68[01-03].
Note: Upon resuming a snapshot, you may find that time-sensitive services may be down (e.g, HBase RegionServer is down, etc.)

...

Update /etc/krb5.conf on the KDC host. e.g. if your realm is EXAMPLE.COM and kdc host is c6401c6801.ambari.apache.org

[realms]
  EXAMPLE.COM = {
    admin_server = c6401c6801.ambari.apache.org
    kdc = c6401c6801.ambari.apache.org
  }

Restart Kerberos services. e.g. for Centos/RedHat

...

cd ambari-vagrant/centos6.48
vi Vagrantfile  <- uncomment the line with "dev-bootstrap.sh"
vagrant up c6401c6801
