I am trying to get a vagrant box up and running, but I keep getting network collide errors. This box is a fresh download of trusty64. I have been searching every file and folder
I had the same challenge, and did the following to solve it:
In VirtualBox, go to File -> Host Network Manager
Take note of the IPv4 address in this window. In your Vagrantfile, use any IP in the reserved private IPv4 network range. Let's say your VirtualBox IPv4 address is 192.168.56.1/24. In your Vagrantfile you could then add
config.vm.network "private_network", ip: "192.168.56.5"
Remember to configure your hosts file accordingly, should that be required.
