Ethical Considerations Hacking A Virtual Environment?

I am currently finalising my project in Uni and in the project planning section is asks if there are any ethical considerations to be made in my project. I am conducting penetration testing on a VIRTUAL network simulator (GNS3) using Metasploit toolkit. I am guessing I will need permission to download these tools onto the university network, would that count as an ethical consideration? If not, what would I say in this section? note, all of the data I am using in the project was created by myself, and there is no other human participation.
