Hey @shelson - thanks for this PR! This definitely seems like an easy win ahead of the refactor coming soon.
I put some general feedback in the PR. There's a few things you can do using both the TF API and Go to make this better.
Thanks!

You can use StringInSlice from the validation package in TF core to make this much easier on the eyes.
The syntax would be here:
ValidateFunc: validation.StringInSlice(virtualMachineNetworkAdapterTypeAllowedValues, false)

This variable should be unexported (starts with a lowercase letter, ensures that no package outside of vsphere can use it - basically a private variable), and be specific enough to avoid collisions.
Suggestion: virtualMachineNetworkAdapterTypeAllowedValues.
Also, you might want to check here to see if there is any appropriate constants you can use.

Here, rather than printing the type out, you should be using the more spec-native type assertion.
The code below would look like this:
if _, ok := device.(*types.VirtualE1000); ok {
networkInterface["adapter_type"] = "e1000"
} else {
networkInterface["adapter_type"] = "vmxnet3"
}You can also use the switch type assertion format as well.
…nd shortened validation function drastically

Hey @shelson, thanks for the update! Next issue: the tests are failing because you haven't run the changes through Depending on the IDE/editor you are using this is set up different ways - if you can tell me I might be able to help. Also see here: https://blog.golang.org/go-fmt-your-code |

Thanks for the awesome feedback - I really appreciate you taking the time to help me get this in a shippable state. I'll work on the go-fmt thing in the morning as it's getting late here now. Thanks again. |
Now that adapter_type has been exposed properly, document it. The adapter types will be improved on during the refactor.
|
LGTM to me now @shelson! Merging now. Thanks for the contribution! |
I needed this functionality and noticed that it was already commented with "TODO". It's my first foray into go so the following might be better worked out another way:
adapter_type_string := fmt.Sprintf("%T", device)
if adapter_type_string == "*types.VirtualE1000" {
Otherwise though it seems to work just fine.
