How to forword firefox running in vagrant machine to local machine? - linux

Question

I am running django project openstack on virtual box. ./run_tests.sh --runserver 0.0.0.0:808. This is responsible to start django project. This is running inside virtual-box, which is created by Vagrant. I want to access this result into my firefox running on the same machine, outside of vagrant.
When I run firefox in virtaul box it gives
Error: no display specified
How I will do that, please check Vagrantfile

# Create a forwarded port mapping which allows access to a specific port

# accessing "localhost:8080" will access port 80 on the guest machine.

If you want to run graphical programs from your vm and forward to your host, its possible. I believe there are different ways but this is what I am using.
Install a X11 program on your host. On mac, you can install xquartz (http://xquartz.macosforge.org/landing/), on windows I am pretty sure there are equivalent but I am not familiar
configure your vm to do x forwarding, add the 2 parameters to your Vagrantfile
config.ssh.forward_agent = true
config.ssh.forward_x11 = true
start vagrant and when you execute firefox it will forward to your host
