My main goal is to have a vm pre-installed with the webapplication I have developed. The web app sits on a tomcat server. So I would like to access it through port 8080. I also wanna use ssh for remote control of this. I have linux users who demand for these things. But before i package the vm, just wanted to explicitly confirm that the system can be accessed through a host OS.

I tried playing around with the options(Enforcing and Disable), i was still unable to ssh into the guest CentOS. I opened port 8080, but still failed. Am using a virtual appliance that only provides me with a command line interface. I liked the advice.
