  1. Add VM template support

    Give the ability to convert a VM to a template, or provide a simple way to sysprep / generalize a machine on import - like shown in VMware.

    Should be a basic Hyper-V feature.

    • High Resolution VMConnection for Linux

      Support for high resolution VMConnection with Windows is great in the 1709 release. When configured as an Enahnced Session, it's capable of dynamically resizing due to its use of RDP.

      Linux won't have RDP built-in which is required at the moment for Enhanced Sessions, but it would be great if the Hyper-V team could come up with a way to support dynamically resizing Linux's most popular Window Systems... X & Wayland.

      I'm not sure how to support X & Wayland. A .deb & .rpm package that installs an "agent" or "Integration Component" that enables this would be great until Microsoft…

      • USB 2.0 & 3.0 Passthru for Hyper-V (Windows Server 2016)

        Currently, if I want to plug any USB 2.0 or 3.0 device into my Hyper-V host and use it through my VM it will not work.

        Make it so number one...

        • Windows Server 2016 Hyper-V GUI for DDA

          I would like to see a GUI set up so that we can find the hardware that we want (PCI Express Devices or USB) and mount them or unmount them via a GUI. This is a lot easier than powershell. Click to mount/unmount hardware from host to VM or vice versa.

          More people would use this feature and it would be easier to mount and unmount specific hardware items.

          • Allow me to set a new minimum memory while VM is running

            I normally next-next-next-finish and end up with VMs set to 8GB max RAM and 512MB minimum. Windows seems to absolutely sip RAM however, and never come close to using the available RAM.

            So I go to increase the RAM...and I get an error messagethat I cannot change the minimum RAM while the VM is running or paused.

            Is there a functional reason for this? It drives me bonkers.

                • Auditing of virtual machine connections

                  I raised that question in https://social.technet.microsoft.com/Forums/windowsserver/en-US/eac58596-2ce1-4612-91be-5b4da7ec4aa3/auditing-vm-connections?forum=winserverhyperv, but obviously that features is missing. I´d like to see auditing of virtual machine connections, i.e. which (obviously authenticated and authorized) user connected (or later disconnected) to which virtual machine (name, guid).
                  Thanks

                  • Hyper-V Default Microsoft Hyper-V Video Adapter

                    Introduce a way to either completely remove the default 'Microsoft Hyper-V Video' adapter, or reassign it as a secondary adapter, when a DDA (SR-IOV) graphics adapter is being passed through to the VM.

                    We have a Hyper-V Server 2016 with a Windows 10 Pro VM configured with a Direct Device Assignment (DDA) GPU passed through to the VM, which is working and numerous tests have demonstrated that the graphics card is indeed able to operate at native speeds while attached to the VM.

                    The problem we're having is only OpenGL software calls work - Direct 3D doesn't work, and any…

                    • Add a virtual hardware firewall to Hyper-V

                      Azure already has some sort of Hyper-V firewall. Bring this to the core Windows Server/Hyper-V product so that we can introduce a virtual hardware firewall layer in our software-defined networking. This is really key.

                      • Fix virtual TPM in Linux guests

                        I run CentOS 7 and RHEL 7 virtual machines on a Hyper-V Server 2016.

                        Virtual TPMs in the VMs somehow worked, at least as entropy sources, before June 2017 Patch Tuesday. After I've applied the latest cumulative patch every TPM got broken on the next VM restart.

                        The bug is a regression between 14393.1230 and 14393.1358.
                        (I've downgraded and everything seems fine now.)

                          That includes ease of use, like the (distributed) vSwitch implementation VMware has.

                          • Add basic disk and network usage counters in console

                            CPU counter is useful, but I more often want to see whether the VM is using a lot of disk access. Adding a column to Hyper-V console for this, even if it only updates every 30 secs, would give me a better idea of what machine is using the disk most.

                            • VSS Hyper-V VM bug

                              There is a bug, uncovered when using Veeam backup software which they describe as -

                              "Application-aware processing of Active Directory domain controllers running on guest OS other than Windows Server 2016 fails with the “Failed to create VM recovery checkpoint” error (32770). This is a Hyper-V 2016 issue that Microsoft is planning to address in the future update."

                              Any news on a fix for this would be great.

                                Please update the docs to mention the need for extra space for VMRS files.

                                • no .indexof in

                                  Microsoft.HyperV.PowerShell.VMSwitch is missing IndexOf method, which makes it tricky to get an index number.

                                  You'll have to pass it to a Customobject, and deserialize the information, if you wanna have any chance of using this.

                                  • Mistake on Japan "Resume-VMReplication" website

                                    Hi You have a mistake on the bottom of the "Resume-VMReplication" website(japan version). The last example for resuming replication for all the VMs are wrong. It should be "resume-VMreplication *" instead of "Resume-Replication *"

                                    • LACP in Virtual Environment

                                      Hi,

                                      Please allow LACP configurations for NIC teaming in virtual environments. This is a possible solution. The only allowed option is "Switch Independent", which is limiting to me. I run LACP configurations in my VMware environment for all my 2012R2 servers now, no issues from this design. Allow me to do this again please.

                                      Thanks,
                                      Nick

                                      • Hyper-V should support VMware Parallels style fullscreen VM as a Windows desktop

                                        In VMWare Parallels on Mac, we have the option of performing a shortcut to jump directly into a VM on a different desktop.

                                        In Windows 10, we now have multiple desktop support, which is wonderful! However if we full-screen a VM, we can't use our normal hotkey to go back to the parent windows desktop. Instead, those hotkeys are interpretted by the full-screen VM.

                                        I think it would be ideal to be able to full-screen a VM and still slide out to my parent desktop. This should mirror the functionality of VMware Parallels on Mac.
