I would recommend to have 2 calls, one to turn it on, and one to turn it off. This is because enums tend to be problematic for upgrades, so I'd rather avoid them

Given we are later going to have an auto mode, I would like to use a single API with different parameters (e.g. on, off, auto, etc). Then we only need to add 1 API instead of adding 3 APIs.

This doesn't look like it's a small one off, but something that needs its design reviewed.
Please add the design to xapi's documentation so we can take an honest look at this code.

I think this all looks reasonable. I don't think a detailed design would be required but some motivation and rationale would be good to have. If we already know that we want additional enums, it might be good to provide them on the API level already but to return an error like "not supported" for them. This would make update cases in the future simpler.

Discussed the design today, we decided to move the 'auto' mode to another API. So the new added API only contains starting and stopping ssh. So I splitted the API to start_ssh and stop_ssh.

If we don't need more than on/off a simpler call ...-enable taking a boolean would suffice. But if we do need more, an enum could be the right choice. We probably should define all planned values right away and avoid extending the enum later, if possible.

Maybe it's not needed but there is no API to observe the status of the SSH service; to be sure, you have to enable it before using it, |
