Not providing a default machine type for Arm is a deliberate
choice: there is no single right answer and the user has
to decide what their preference is. We used to have a default
machine type set, and it caused a lot of user confusion as
they expected Arm to be like x86 where everything will run
fine on the default machine type and it did not, which is
why we switched to not having a default.
