Is it possible to have a repository created for Fedora 27?

I would create an enhancement ticket at bugtracker and ask the DEVs to set one up when they find the time.
But if I am correct isn't 27 still in beta? If so then it would probably not be created until after the actual release and tested.

You are correct, it is still in beta. Just thought I would test 2.0 on this machine and forgot I put the beta on it.

At this time others are using the fedora 26 build on 27 and you can do this by downloading the package from https://www.virtualbox.org/wiki/Linux_Downloads and install it yourself instead of using the repo.
