Comment 2 for bug 1810966

Failure 1:
Ok I cleanly installed again Centos 7 on Baremetal and restarted the installation.

Followed the steps in below :
https://docs.openstack.org/tripleo-quickstart/latest/basic-usage.html#tripleo-quickstart

Create a superuser and login to the superuser user

su - user
    1 export VIRTHOST=127.0.0.2
    2 echo $VIRTHOST
    3 bash quickstart.sh --install-deps
    4 curl -O https://raw.githubusercontent.com/openstack/tripleo-quickstart/master/quickstart.sh
    5 screen
    6 bash quickstart.sh --install-deps
Error :
/home/user/.quickstart/playbooks/teardown-provision.yml
SSH Error: data could not be sent to remote host "127.0.0.2". Make sure this host can be reached over ssh
Resolution :

 7 ssh-keygen
    8 echo $VIRTHOST
 127.0.0.2
    9 ssh-copy-id root@$VIRTHOST
   10 rm -rf _quickstart.log
   11 rm -rf ./.quickstart/

Restarted the installation again:
 12 bash quickstart.sh --tags all $VIRTHOST

Got Error again :

the _quickstart log attached. Now trying to find the overcloud_deploy.log and will share shortly.
