VMware vmnet2 routes collide with en0

Question

I am getting the following error when starting a vagrant box:

gajus:vagrant gajus$ vagrant up
Bringing machine 'default' up with 'vmware_fusion' provider...
==> default: Checking if box 'puppetlabs/centos-6.5-64-puppet' is up to date...
==> default: Verifying vmnet devices are healthy...
The VMware network device 'vmnet2' can't be started because
its routes collide with another device: 'en0'. Please
either fix the settings of the VMware network device or stop the
colliding device. Your machine can't be started while VMware
networking is broken.

Routing to the IP '192.168.1.0' should route through 'vmnet2', but
instead routes through 'en0'.

This is my ifconfig:

Can anyone explain what is causing the issue and how to prevent it?

Answer 1

I had this issue on OSX (10.10.2), running Vagrant 1.7.2 and VMWare Fusion 6.0.6, but I had the error message:

Routing to the IP '192.168.1.0' should route through 'vmnet3', but instead routes through 'en0'.

To fix this, I:

1. cd /Library/Preferences/VMware\ Fusion
2. Removed all mentions of VMNET3 from networking. (before doing this,you should back the file up.)
3. cd <where your Vagrantfile is>
4. vagrant up

The VM was successfully brought up.
