Uncompressing vm image file

- The filename used for the vm images has changed, and
  the files are now compressed with gzip so after downloading
  they need to be uncompress. Also the filename used to save the
  qcow2 files is programatically determined.

- If a newer vesion of tmate is installed script shoudl not exit
  with error.

 # Instructions
 
+## 0) Pre installation
+
+Enable the appropriate openstack repo. 
+From the output of 
+
+ `sudo yum search release-openstack`
+
+install the desired repositories for the release you want to use. For example: 
+
+ `sudo yum install centos-release-openstack-rocky`
+
+Install openstack client
+
+`sudo yum install python2-openstackclient`
+
+Install git
+
+`sudo yum install git`
+
+Configure stack user to use ansible <2.9 (2.9 does not support he "failed" filter).
+We have to do it at the root level because some of the playbooks apperantly are run 
+under root, so just changing it at the user level will not work. 
+
+`sudo pip uninstall ansible`
+
+`sudo pip install "ansible==2.8.7"`
+
+Then verify that you ansible version is 2.8.7
+
+`ansible --version`
+
+Clone this repository:
+
+`cd <to_wherever_you_want_this_source_code_to_live`
+
+`git clone <this repos address>`
+
+
+CD to repo
+
+`cd ocp-doit`
+
+Get the lastest artifacts hash for the tripleo  if you want to use it, and set it in common.sh
+you can get it from:
+
+` https://trunk.rdoproject.org/centos7/current-tripleo/commit.yaml`
+
+by joining the `commit_hash` with the first 8 characters of the `distro_hash` with a `_`. 
+For example:
+ 
+    commit_hash: 38c4e3104abdeb4699cfbe7a78fa2f37d7a863b4
+    distgit_dir: /home/centos-master-uc/data/puppet-manila_distro/
+    distro_hash: 93bde36c78d20a482068674c1391725cdf89b6d9
+
+then the hash becomes:
+
+`38c4e3104abdeb4699cfbe7a78fa2f37d7a863b4_93bde36c`
+
+Install and configure a dns server on the host machine (The machine with the LOCAL_IP address).  The LOCAL_IP
+address is used as the dns server for the host as well as the forwarder for the Neutron dnsmasq and other dns services. 
+
+example /etc/dnsmasq.conf
+
+    domain-needed
+    bogus-priv
+    server=192.168.122.1
+    conf-dir=/etc/dnsmasq.d,.rpmnew,.rpmsave,.rpmo
+    
 ## 1) Create local config
