Vagrant network collides with a non-hostonly network

Question

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 dealing with vagrant trying to find something specifying an IP I can't. I am running vagrant on a windows 7 machine. Here is my Vagrantfile:

C:\Users\.vagrant\boxes...\Vagrantfile

Vagrant::Config.run do |config|
  # This Vagrantfile is auto-generated by 'vagrant package' to contain
  # the MAC address of the box. Custom configuration should be placed in
  # the actual 'Vagrantfile' in this box.
  config.vm.base_mac = "0800278493DB"
end

# Load include vagrant file if it exists after the auto-generated
# so it can override any of the settings
include_vagrantfile = File.expand_path("../include/_Vagrantfile", __FILE__)
load include_vagrantfile if File.exist?(include_vagrantfile)

This is the error I receive from a vagrant up command:

Bringing machine 'default' up with 'virtualbox' provider...
==> default: Clearing any previously set network interfaces...
The specified host network collides with a non-hostonly network!
This will cause your specified IP to be inaccessible. Please change
the IP or name of your host only network so that it no longer matches that of
a bridged or non-hostonly network.

How do I get the IP on my virtualbox not to collide?

Answer 1

Check the IP you have on your LAN connection and make sure no devices are colliding with the IP on your Vagrantfile.

I got this error and I had 192.168.1.2 on my laptop's wifi and I was setting 192.168.1.10 on my Vagrantfile. So I changed the IP on my Vagrantfile to 192.168.2.10 to make sure it won't collide with any device on my network.

Answer 2

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.

Answer 3

I had the same issue when I was working from home so what I did on my Vagrantfile was:

# app.vm.network :private_network, ip: '10.0.0.07' # work
  app.vm.network :private_network, ip: '192.168.56.77' # home

and I comment/uncomment depending on where I am.
