This commit adds a new option, `vmx_remove_ethernet_interfaces`, to both
of the VMWare builders. This is useful when building Vagrant boxes,
since Vagrant now produces output such as:
```
WARNING: The VMX file for this box contains a setting that is
automatically overwritten by Vagrant when started. Vagrant will stop
overwriting this setting in an upcoming release which may pre vent
proper networking setup. Below is the detected VMX setting:
ethernet0.pcislotnumber = "33"
If networking fails to properly configure, it may require this VMX
setting. It can be manually applied via the Vagrantfile:
Vagrant.configure(2) do |config|
config.vm.provider :vmware_fusion do |vmware|
vmware.vmx["ethernet0.pcislotnumber"] = "33"
end
end
```
This can be avoided entirely by removing the ethernet adapters from the
VMX file prior to packaging as a Vagrant box, in which case adapters are
created as expected according to the Vagrantfile specification.
This is more than I planned but I think it makes things a little clearer
and perhaps organizes the page more clearly? I'd be happy to take
another example for template variables if someone can posit one.
In AWS we can derive the `VpcId` and AZ from the `SubnetId`, so now we do. In the config you can now only specify the `SubnetId`.
This fixes issue #4693.
