2. create vm as per your usecase like os flavour/family can be RHEL or CentOS .

[root@ansible packstack-ansible]# ls -lrt
total 4
-rw-r--r-- 1 root root 3166 Mar 15 01:49 README.md
drwxr-xr-x 3 root root   86 Mar 17 11:04 redhat

drwxr-xr-x 3 root root   75 Mar 17 11:05 uninstall
[root@ansible packstack-ansible]# 

4. Change the "ip_addr" in the env_variables file with the IP address of your created vm.

[root@fyreansible packstack-ansible]# cd redhat/	### folder may vary according to OS family e.g. redhat / centos
[root@fyreansible redhat]# ls -lrt
total 12
-rw-r--r-- 1 root root 198 Mar 15 01:49 setup_packstack.yml

5. provide your vm ip in inventory file along with your user and password in below format. Note: Below is just a sample IP, may be vary.

   10.20.30.40 ansible_ssh_user=root ansible_ssh_pass=Passw0rd@1234

6. check once whether your vm is accessible from ansible server with below command , if you get pong response like "pong" this mean your vm is accessible.

   ansible all -m ping
   
   10.20.30.40 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
    }

7. Run the following command to start the installation.

   http://<vm_ip>/dashboard

9. at the end of execution of above ansible playbook , you will get the username and password as well.
10. After completion of installation you can login to packsack instance and access the rc file with below commands and validate your installation.
