          nothing new... reboot/shutdown -r just shuts down the machine.
          [this is the SAM curse :P]

          edit...

          no it is not the SAM curse: even centos7 doesn't not reboot when asked...

            ok, just installed a win server core 2012R2 VM. even this doesn't reboot 😕

            I'm surely doing something wrong but I really really don't know what and where to start searching for...

              Why doesn't sudo reboot now work?

                Or why aren't you able to reboot via the Hyper-V management interface?

                  @DustinB3403 because the machine shuts down but then it doesn't boot! it is like if you issue shutdown without -r.
                  This is the same with reboot or so. Also because all this commands are symlinks to systemctl.

                  there is something broken in the way hyper-v vUEFI is managed on ALL my VM.

                      So if you did issue a reboot from the management interface, the VM just shuts down. Rather than actually rebooting.

                      Seems like a huge failure there if that's true. What hardware is hyper-v installed on?

                        what's this? I just have the "shutdown" button on the hyper-v GUI (win 10).
                        also if I enter a remote session in powershell and issue:

                        Restart-VM -Name VM-NAME-HERE

                        the machine shuts down it doesn't restart!

                          HPE DL380G9

                          I suppose something is broken in my setup: it is not possible people did notice this basic item!

                            According to the HPE HCL the hardware is fully supported...

                            Is anyone else experiencing the same results?

                              found anything on the web, going to call HPE support... but I'm a bit in a hurry. hoped for a fast solution on-line 😕

                                I've not heard of anyone having this issue. You might have something unique here.

                                  yes. until it was ubuntu I was thinking about something strange in the vUEFI. but even win over win...

                                    NOT what you want in IT. I'll be waiting to see what the problem is.

                                      If the VM does not start at all, then what is in the container won't be the issue.

                                        mmm... got this:

                                        Restart-VM -Name zi-erp-as

Confirm
Are you sure you want to restart virtual machine "zi-erp-as"?
[Y] Yes  [A] Yes to All  [H] Halt Command  [?] Guida (il valore predefinito è "Y"):
Restart-VM : 'zi-erp-as' failed to change state.
    + CategoryInfo          : NotSpecified: (:) [Restart-VM], VirtualizationException
    + FullyQualifiedErrorId : OperationFailed,Microsoft.HyperV.PowerShell.Commands.RestartVM

                                        And the machine just stops.

                                        Now performed a sequence of start-restart with no idle, just waiting in VM Manager to see the CPU go down and then fire the restart. So far so good... really weird. Let's the VM stay idle for a while and retry!

                                        Yep! if the machine stays idle for a few tens of seconds everything go nuts:

                                        Restart-VM -Name zi-erp-as

Confirm
Are you sure you want to restart virtual machine "zi-erp-as"?
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [?] Guida (il valore predefinito è "Y"):

    + CategoryInfo          : NotSpecified: (:) [Restart-VM], VirtualizationException

                                        Not this specific error but when people get this "change state" suggestions are to rebuild the machine 😕 but those are all brand new.

                                        Apparently this is not the case with:

                                        Stop-VM -Name zi-erp-as; Start-VM -Name zi-erp-as

                                        But this is a no go for remote administration from within the VM. Need to sort this out 😞

                                          even tested a gen1 VM: not different.

                                            ok, just got that Restart-VM does an hard restart (removes the plug). just forget it!
                                            still missing an answer...
