      Hyper-V is not Windows.

      Managed with Windows tools, it sure works/runs just like it.

      But it isn't at all Windows. It literally shares nothing in common with Windows, besides the developer.

        I can administer a Hyper-V server and VMs and it looks just like any other Windows server I administer. It shares a look and common practices.

        For example, using Disk Management to adjust disks.

          It is 100% Windows. why the hell would you even think it is not?

          It is Microsoft Windows Hyper-V Server 2016.

              Now I wonder - does it run on the Windows kernel?

                Nope, the kernel is Hyper-V

                  As with many things in the Windows world, "looks like" isn't the same as "is". Ubuntu looks like Linux, but is Windows on Windows.

                    Yeah. Being an old-time UNIX person I went with KVM. Stick with what you know best when all else is equal, and Hyper-V/KVM are quite close feature wise.

                    Being a Linux noob, is what is pushing me to Hyper-V.

                    Though none of my test machines will install it since 2016 requires SLAT. Again, what a pain.

                    golf clap Good man.

                    I was tempted to go KVM. But TBH I think the world of support is so much larger for Hyper-V.

                    The amount of people using it is greater. The quality, well, that's another matter.

                    KVM has more? I'd expect way more, especially as Amazon moves over.

                      If Hyper-V was Windows, it wouldn't need Windows in the Dom0. It's specifically that it isn't that that is required.

                        Now I'm lost - Hyper-V still has a Dom0 even when installed as pure Hyper-V?

                          It's really more back to the basics of not knowing enough Linux.

                          XS was definitely easy. If you didn't mess with it (our newly coined phrase "the first rule of XS") it was plug and play.

                          But I'm not sure KVM is going to be like that.

                          When you install CentOS/Fedora check the box for hypervisor role. Done. You have a KVM box.

                          Virt-Manager only runs on nix but cli is easy to use. Esp when you can just do

                          virt-builder fedora-26 -f qcow2
                          

                          and you have a disk with Fedora26 ready to go. Just define the VM and attach that disk and you’re done.

                              Of course, that's not an architectural element that could possibly change. That would make it a totally different product altogether.

                              Remember the simple mantra - Hyper-V is always the same thing, no matter how you install it.

                                  Oh man I only just really started using XEN better get that test server racked and KVM installed lol

                                    Now is the chance to get ahead of the curve rather than behind it 🙂

                                      You never question why for a Hyper-V Core required so much damn install space? The Management VM (DOM0) just runs headless.

                                        TBH if you look at really small partitions maybe Hyper-V requires one of the biggest (but not sure about KVM), anyway my hyper-v install is around 26GB. not a big deal .

                                          Yeah I can't imagine an SMB who cares about <30gb for a hypervisor.

                                            Do you mean <30GB? Because at some point larger than 30GB, everyone cares. What point, I don't know, but at some point, for sure.
