I am trying to automate editing a serial device on a guest VM. I can do so using vSphere SDK. However, because we are using free version of ESXi, we can only use the vSphere SDK for read-only operations.
I have noticed that there are some unofficial tools, such as vim-cmd (vimsh), that can also automate some tasks in command line. But can I use it to call SDK? Or are there any other 3rd party tools that can work with SDK for write operations, without purchasing a license for ESXi?
