Example of deviceChange?

[moralloki]

I'm looking for an example of how to fill in the information for deviceChange (for the spec in a VM clone). In particular, I'd like to be able to modify the NIC settings. I understand how to do this in pyvmoni but I'm not sure what the YAML is supposed to look like in the playbook. If there's another example that you have outside of the NIC, that would probably be helpful too.

I've tried the following as an example:

              config:
                VirtualMachineConfigSpec:
                  name: "testName"
                  memoryMB: 2048
                  numCPUs: 1
                  deviceChange:
                    files: {
                      VirtualMachineFileInfo: {
                        vmPathName: "[datastore]testname"
                      }
                    }

This always ends up with:
TypeError: For "deviceChange" expected type vim.vm.device.VirtualDeviceSpec, but got str
