Not able to connect to sample app 12c linux server

Question

Hello expert

I have installed 12c virtual machine sample app in order to learn OBIEE 12c. I have started virtual machines and started all the BI servers. But the when I am trying to connect to enterprise manager from host machine web browser by http://demo.us.oracle.com:7001/em, then it is failing to connect. Any guess why this is happening.

Thanks in Advance

Certainly I do care of the expert reply. However I try to come to solution by doing some trial and error by myself, by doing some research from internet. May be the solution is not best.

Anyway thanks for providing right information.

Thanks

Apparently you don't really care about replies, but stop doing that, it's a useless step !

Your VM get an IP by your network DHCP, which means it can potentially change IP at every start. So you end up editing your host file all the time.

It is useless, use the IP directly instead of demo.us.oracle.com !

The VM needed that because it's a good practice for the install to have a hostname/domain mapped to the host itself, but you don't need to use that domain yourself when connecting to it.
