          So just the fact that you are running it as a VM makes all the difference?

          If you run it on hardware, can you reboot normally?

          Is it just with Hyper-V? Have you tried it on other hypervisors?

          What happens if you install the latest actual LIS drivers from Microsoft?:

            I never have any problems. I just did this.

            Hyper-V Server 2012 R2 with a CentOS 7 guest in a Gen 2 VM.

                you mean linux or windows? well yes never got issues on HW. but don't know on THIS HW!

                Is it just with Hyper-V? Have you tried it on other hypervisors?

                same linux machines on kvm run perfectly and autoreboot at every update

                ubuntu has them built in. windows vms don't need...

                    @black3dynamite @Eltolargo @Tim_G latest kernel and tools are installed from the HWE stack. this doesn't help. just tried again from a VPN to my office. Also hell win2012r2 doesn't reboot in hyper-v 2016.
                    monday I'll reboot the server from within the server room, with a monitor attached. let see if something strange happens even at hw level...

                        Looks as if there is more issues with that server than just VMs restarting. Are there any pending updates on it?

                          @Eltolargo no just a windows defender update pending. server has been restarted after last update batch.

                          looking now at ubuntu VM in the last reboot I see this:

                          reboot   system boot  4.8.0-41-generic Sat Mar 25 18:21   still running
                          reboot   system boot  4.8.0-41-generic Sat Mar 25 18:48   still running
                          reboot   system boot  4.8.0-41-generic Sat Mar 25 15:15   still running
                          reboot   system boot  4.8.0-41-generic Sat Mar 25 15:11 - 15:14  (00:03)
                          reboot   system boot  4.8.0-41-generic Sat Mar 25 15:10 - 15:11  (00:00)
                          reboot   system boot  4.4.0-66-generic Sat Mar 25 15:00 - 15:11  (00:10)
                          

                          3 sessions still running! bah this is for sure something broken...

                            You have never shown your Hyper-V configuration.

                              @JaredBusch yes... Err... what conf? The vm conf (always the same) or the hypervisor itself?

                                Disabled hyperv time services and forced linux rtc to utc. Now monitoring drifts ( never say never). but win2012r2... Don't know..

                                  I know it's built in. But I would still try the latest from Microsoft as a troubleshooting step.

                                    The downloads from Microsoft is for Red Hat and CentOS. For Ubuntu, installing linux-virtual package is all that is needed.

                                        OK now I've eliminated some drifting in RCT <- yes RCT. I've monitored both gen1 and gen2 vm for something like 12 hours. no drift in 12 hours of VM idling.

                                        this doesn't solve the thing: issued a reboot. got a shutdown! but at least without timing integration services now clocks seems logic in the VMs. I think even @JaredBusch got issues with timing and constant time reassignments...

                                        I've also rebooted the server from the closet, nothing strange in the reboot sequence: all ok with the hypervisor. I've a new win update. let's apply this. also let's check the "latest" HPE service pack from october 2016, maybe some driver is apparently ok, but requires update...

                                        bah. I'm going to think it's me. I'm cursed w/ hpe stuff.

                                        A last thing remains: enter bios disable power savings and CPU c-states and let's see... then I'll STONITH my self 😕

                                        f#@*$%!

                                          definitively a platform issue. last resort: reinstall all.

                                            Are you running Server 2016 on your PC?
