I created a pull request for this issue #20, which incorporates a way to add private network IP address to customization spec.

This is my first time to create a pull request in Github, let me know if this is okay. Thanks.

Let me know if these changes make sense and work for you.

Thanks

I checked out the v0.5 and it worked for me without any further change. I think it makes sense to have multiple IP addresses/NICs but I don't have the chance to test it, at present I only verified the one NIC case since that is the hardware settings I have in vSphere. Thanks so much for this.

Great, glad it worked for you. Thanks for testing this out.

i saw the above mentioned using a customization spec. I'd imagine in the vagrant file that'd be "customization_spec_name". can you provide an example of what the value would be or a common example of the path to it as found in vcenter, i.e vsphere.template_name spells a path to the template. Thanks in advance!
