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

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

          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#@*$%!

                  latest news: my pc with hyper-v correctly reboots everything! everytime! vene without latest kernel/hyper-v stuff in VM!

                  definitively a platform issue. last resort: reinstall all.

                      It's windows 10, so yes, in theory, it is the same hyper-v stack.
                      Honestly the only thing I can think of is issues with ACPI with the cpu. I've even disabled any energy saving but nothing!
                      if I keep the VM idling too much it stops and not reboots... any VM.

                        LATEST NEWS:

                        yesterday, after a number of tests VM did freeze at reboot command rather than shutdown. As a last resort I've chosen to format SD/rest bios and restart from scratch.

                        My installation procedure did not work anymore... hell 2 times was right the third has failed...

                        called HPE this morning, they have asked me to do some tests via Intelligent Provisioning. IP. chrashed with missing linux kernel file (IP is based on linux)

                        they will start mobo substitution procedures tomorrow morning.

                        F*#@ wasted 15 days.

                        15 D.A.Y.S.

                        ever seen a failing server MOBO? I've. And I've provisioned just 3 servers in my life!

                          @matteo-nunziati that sounds like a pain. Hopefully the issue is resolved after the changes.

                              OK,

                              some news here after full rebuild of server.

                              MOBO failure was an extra, still VMs do not reboot.

                              well, not exactly...

                              we have installed some windows core, some ubuntu bare server, some windows full gui, some ubuntu server with full MATE desktop.

                              now the "barebone" VMs do not reboot, they just shutdown.
                              The full bloated VMs restart nicely!

                              I think this is something to do with the speed of the reboot cycle... but even my reseller tech ignores what to do... HPE is finally thinking to pass me to L2 support.

                              project is delayed at least of 1 week wrt deadlines (and I've kept 1 extra week at the time, just in case)

                                  You can do that with a remote company too. But calling someone's cell phone isn't professional and introduces a single point of failure.

                                    not my decision. I was going to settle with dell stuff with another reseller, offering help desk with SLA + 24/7 dell onsite. but they (company) wanted the sysadmin to be physical and periodically "visible"

                                      I was only saying that remote companies can provide local resources. There is no connection between where a company is based and where their staff are based or can appear.

                                        OK, just for the sake of statistics,

                                        how many of you run hyper-v server 2016, I mean the Core version, without GUI.
                                        how many run on HPE HW?

                                        thank you!

                                          Used to, but not any longer. Moved to Dell.

                                            We still have a lot of HPE. Starting to get more Dell though.
