Deploy ovf file to an 'internal' Esxi host

Hey all,

I am trying to optimize the way that i use to deploy VM from ovf file to ESXi host: i would like to do this programmatically even if the Esxi host has not a public ip.

I explain: actually i'm using ovftool and vijava to deploy VMs, and they works fine, until i try to deploy in a local Esxi host (ip is not public)
So my question is, does anyone know if there is a tool or a library that i can use to deploy an ovf to 'internal' Esxi host ?

Thanks,

Sohnoun.
