The new SDK is completely different from the old one, that is why I
deleted everything and added the new one. A diff won't help you find the
differences.

The main difference is that in the new SDK types and services are
separate things. In the previous version of the SDK methods like "start"
used to be part of the "VM" class. This doesn't reflect the actual
design of the API, as you may get a VM from places where "start" doesn't
make sense, for example, a VM to be imported from an export storage
domain. This caused many issues in the previous SDK. In the new SDK
types are just containers for data. Operations, like "start" are part of
services.

I suggest you look at the examples:
