What's the difference between "Turn Off" and "Shutdown" in Hyper-V

  • 772

It seems like a simple thing to find the answer too. But, I can't seem to find it in the Hyper-V doc. I'm sure it's there somewhere.

Simple question, when I am in Hyper-V manager there are two options that seem similar but I am sure they are different. "Turn Off..." and "Shut Down..." What do they each do?

My gut tells me that "Turn Off..." is like pulling the plug on a physical machine where as "Shut Down..." sends a shut down message to the guest. Is that correct?

In both cases is the VM no longer running and using memory and CPU resources on the host.

  2. Not quite, at least in concept:

    < PULLING THE PLUG > The 'worst' you could do in terms of control, i.e. no control.

    < TURN OFF > Should have a circuit which takes care of the hardware components, i.e. makes sure that various components are properly turned off. = take care of hardware stuff -> < TURN OFF >.

    < SHUTDOWN > = take care of software/OS stuff (e.g. save files) -> < TURN OFF >.

  3. Have a look at this blog post from the virtual pc guy: http://blogs.msdn.com/b/virtual_pc_guy/archive/2011/01/10/turning-off-a-virtual-machine.aspx

    When you select to “turn off” a virtual machine – you are actually getting an “old school” “cut the power” kind of turn off.
