setting vhv.enable or nestedHVEnabled

[Rex Roof]

I'm trying to use pysphere to turn on nested virtualization on ESX.

I'm able to change this setting using the vcenter web ui but I've been unsuccessful using pysphere.

This is what I've been trying:

settings = { "vhv.enable": 'true' }

new_vm.set_extra_config(settings)

I've tried changing the value to TRUE or to 1 and neither results in the vmx file being updated. 

I came across this post:

https://communities.vmware.com/message/2457426

which mentions a "nestedHVEnabled" option in powercli, I don't know how that would reflect to pysphere.

Anyone have any luck with this?
