Why is there no reboot option in Hyper-V?

All I see when I right click my servers is "reset" and there is no reboot option. Reset isn't the same, right? So how can I reboot as opposed to resetting?

Use elevated PowerShell to manage Hyper-V. In screenshot below I have booted a vm, then restarted it and finally shut it down:

Start a vm:	Start-VM "vm name"
Restart a vm:	Restart-VM "vm name"
Shut down a vm:	Stop-VM "vm name"

Use Reset only in emergency situations when vm simply does not work, is totally frozen. It's hard reset, same as if you hold down the power button on a physical machine for a few seconds to make it turn off instead of shut down, then start the machine again.

Any chance you can answer WHY there is no option to reboot? Even though it is a stated option when researching Hyper-V? So are you saying that there is no option to reboot a vm without using powershell? That makes no sense/

Hi there

Reboot actually doesn't mean anything for a VM - the terminology used is POWER OFF and POWER ON (sometimes also RESTART GUEST).

This will shut down the VM process --you will get back to the start screen with the VM config options.

If you want to simply reboot the OS that's usually done from WITHIN THE GUEST.

Might not seem much of a difference - it's just the "technical terms" used within the VM context - doesn't matter what VM software you are using.

The manager has a "Shutdown" option in the context (right-click) menu, and, when the guest is off, it has a "Start" option. Thus it should be trivial for them to combine the two in a single menu item.

There are often situations when I need to ensure that a half-dozen or more guests get rebooted before I leave the office. I really don't want to wait and watch each one finish shutting down before I can restart them. If I had a "Reboot" option, I could simply click reboot on each one of them and leave.

As all the guys said to you, there is no such thing as a "Reboot" button for virtual machines, neither of the available options offer that, not even Virtualbox, VmWare, Hyper-V...

This is done inside the VM, like it it was a normal computer, you got to start menu and look for shutdown options and then choose reboot... there cannot be a reboot button simply because it must need to send the reboot instruction to the VM, so the OS closes all it's tasks, frees memory and shuts down, and afterwards, commences all the booting process again.

If you use Hyper-V, @Kari already gave you an option so you can reboot your machines all at once, but still, that resets the machine, doesn't trigger the reboot process, which is entirely different, if you restar machines willy nilly, you can cause many errors and problems with services and OS components that need a shutdown instruction to not fail.

I use VMWare... and not even me has a button for reboots... I think that doesn't exist...

KVM has the restart option "button" so there is such thing in the realm of VM:




but if you need to restart several machine you better go
with a script in powershell

Semantics, really. Since VMs live as a Guest under the Host, the term "Reboot" applies to the host system. In any virtual system, the term usually seen is "Restart Guest", or something of that nature. Which will re-initialize the Guest as if you had "Booted" it. Just words. An example from VMWare on my machine:

It's not semantic it's a very different feature, that operation would possibly damage the guest OS, and does not perform a clean reboot
you also get a warning if you try to use it:




it is very different from a clean reboot that safely disable all guest OS services to perform a clean reboot
(probably what the OP is looking for)
