down vote I was having the exact same issue, cannot hit the CM login using public DNS or IP on port 7180. Following steps will help you : iptables stopped (service iptables stop)
SELinux disabled (got to /etc/selinux/config and disbaled the selinux)
curl/wget localhost:7180 works (check the curl status)
ufw allow 7180
service httpd status should be running.
check va/log/cloudera-scm-server log : if any error found then troubleshoot the error
cloudera-scm-server status (should be running state)
netstat -nap | grep 7180 returns (if running other service then kill it) telnet localhost 7180 (should be connected)

I downloaded the virtualbox version of the 5.12 Quickstart VM to double check your results. After unzipping the download the OVF file was present so perhaps you had a corrupted download.
While I have you, I would suggest checking out our community article How to setup Cloudera Quickstart Virtual Machine for instructions on installing the VM as well as common issues people run into.
I hope this helps get you started. 🙂
