I did the following to make sure that the installation is right and to test neutron:

#do not update with ### yum update ### it will upgrade the RHEL 7 to 7.6 Maipo if you want to keep 7.0 on your VM
yum install -y openstack-packstack --skip-broken

then I installed and configured using:

packstack --answer-file=/root/answer.txt --timeout=9999999999999 --debug

and it worked now the installation is complete for sure now:

[root@localhost amer]# packstack --answer-file=/root/answer.txt --timeout=99999999999999 --debug
