In my opinion start, stop, restart is better than the mix before and 
semantically more accurate than boot, shutdown, reboot. The latter uses 
terms that apply to the operating system inside the domain rather than 
the domain (virtual machine) itself.
So I would even go so far to mark the latter group as legacy and 
recommend the usage of the former.

Now it would be a good time to correct the documentation. In reality the 
restart/reboot is a combination of stop/shutdown followed by an in-place 
reset of the domain (at least for QEMU/KVM). Which can behave the same 
as a reboot but doesn't have to. This is one area of confusion for users 
I have observed. Restart seems to raise a lower expectation level ;-).
For that reason I would also vote to exchange the order of appearance 
(restart first).

Same suggestion: first line stop, second shutdown.
