      (yeah I know, we can have remote management, but company is not ready for this, they want sys admin cell phone and they what to touch sys admin like a sky-alighting divinity)

      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.

                We are almost exclusively Dell here... and have been for a while... We still have a couple of PowerEdge 2950s that are in service (but soon to be retired).

                  OK,

                  new poll!

                  how many of you do change the default VM paging location?

                  BTW, what the hell is VM paging and how can be this of any use for linux VM?

                      so basically this is hypervisor provided swap, before vm inner swap!

                        and after a lot of episodes, I've fixed the thing.

                        please let me state this again: I HAVE.

                        I.

                        Not the HPE support, not the reseller tech support.

                        I HAVE.

                        I = An almost idiot ex-embedded sw developer illogically cast into the sysadmin role of a non-sense company!

                        TL; DR:
                        there was a mismatch between OS version, bios version, controllers firmware version, controller drivers version. Selecting the right combination has (apprarently) fixed the issue!

                        how storage controllers affect reboot signals is still a mistery... but actually all was related to the smart paging I mentioned before. Moving it from the default location caused all the issues.
                        I have discovered the "bug" recreating a new vm with copy-pasted hdd but with hypervisor defaults... 2 twins VM one running one not... only difference: location of the smart paging file. XD
