  1. Logs 18304 and 13002 (Bug).

    I am using Windows 10 Pro, version 1909, the same comes enabled by default, use automatic checkpoints, when creating the virtual machine, it generates two logs, with the following IDs 18304 and 13002 in Hyper-V-VMMS.
    But it turns out that the logs are not showing up.

  2. Hyper-V 2019 - Guest VMs shutdown unexpectedly

    When the host server shuts down, a bug in which guest VMs are not automatically shut down occurs in Windows 10 1809 or Windows Server 2019.
    It is also a topic in the forum.
    Please solve this bug as soon as possible.

  3. Hyper-V Server 2019 is missing the Remote Desktop Virtualization Host feature

    Previous versions of Hyper-V Server included the Remote Desktop Virtualization Host (RDVH) feature. Installs from the June 2019 .ISOs don't have this feature.

    "Add-WindowsFeature –Name RDS-Virtualization"

    doesn't work.

    Previous versions of Hyper-V Server included the RD Virtualization Host feature for VDI deployments. Please restore this capability.

  4. Start VM during backup

    Current behaviour:
    When a backup is running, you can not shutdown or start a VM from the console. (but you can do a shutdown or restart from the guest os)

    The problem:
    When a VM stopped, for whatever reason, you have no way to start it again - except by killing the VMMS service or by stopping the backup - both not really acceptable solutions.

    Solution: Just let us start a VM when the backup is running.

  5. Is Nested virtualization and VGA Passthrough concurrently supported inside hyper-v VMs?

    Is Nested virtualization and VGA Passthrough concurrently supported inside hyper-v VMs?

    I have successfully passed through a NVIDIA Quadro P2000 inside a GEN 2 hyper-v on Windows Server 2019.
    When I try to enable nested virtualization support the VM wont boot.

  6. Dynamic memory: provide a maximum with virtual memory setting

    Current behaviour:
    You are able to set a maximum RAM value for the guest. When the guest needs more than that it will swap to it's own paging file.

    Problems:
    When a guest is swapping to it's paging file, this gives a heavy disk load on the disk store where the vhdx is stored, causing all VMs on this store to slow down. It also causes problems with replication, as the pagefile is replicated too.

    Solution:
    Add a Virtual memory amount that is added above the maximum RAM amount.

    Hyper-V will then provide diskspace as RAM to the VM, but…

  7. replication HRL files should be stored on a seperate path

    Current behaviour:
    All HRL files are stored on the same path as the vhdx file.

    Problem:
    This doubles the write load on this drive; all changes are written to the vhdx and to the hrl, on the same drive, which limit the throughput on this drive for the users. It also doubles damages the SSD's by doubling the writes.

    Solution: Store the hrl files on the user defined path, so we can use another array for those files.

  8. Generation 2 machines can't use Host's DVD

    A Gen 1 server can use the host's DVD player to install OS (add a DVD player to IDE controller and point it to the physical DVD)

    Why can't this option be available on Gen 2 machines as well?

  9. Allow host to run other hypervisor (via Nested virtualization)

    Currently Hyper-V locks out other virtualization apps when installed on host. But it is also said that Hyper-V upon installation essentially makes a "host" just another (although privileged) guest. Likewise, we know that nested VMs are supported for a while now. And I tested, it does support other 3rd party virtualization software in a guest.

    So why not allow (even if only via Powershell) option to enable "nested" for a host OS as well?

    Current workaround is : Windows host with Hyper-V -> Windows guest VM for which nesting was enabled -> 3rd party hypervisor -> <something running in it>

  10. Fix Mac Address spoofing in Hyper-V 2019

    When we have a virtual router as a VM on Hyper-V 2019 running a setup that requires Mac Address Spoofing to be enabled, then performance is really bad.
    We have testet with routers based on Windows Server 2019, Linux and BSD, and the results are the same.
    Migrating the same VM's to a Windows Server 2016 node, the problem is gone.

    It seems to be a problem related to Hyper-V 2019 "Mac Address Spoofing" function

  11. DirectX support for Hyper-V Virtual Graphics Adapter

    The graphics adapter lacks certain functionality to run software that relies on DirectX.
    For example Kodi won't run returning error 887A0004 - DXGIERRORUNSUPPORTED
    AFAIK this indicates that DirectX is not supported.
    As on Server 2019 the support for RemoteFX 3D has been deprecated, there seems to be no way to make it work.
    This is unacceptable. The graphics Adapter should be enhanced to support this.

  12. Allow/Support USB port redirect from physical host to virtual machine

    Please finally allow physical USB port redirection to a virtual machine. I know this would limit high availability of the virtual machine but sadly some applications/hardware still require com port communications.

  13. Suppress SPN registration for Hyper-V services

    In domain environments when the Hyper-V Virtual Machine Management service starts it registers six SPNs on the system's computer account in AD corresponding to three services:
    - Hyper-V Replica Service
    - Microsoft Virtual Console Service
    - Microsoft Virtual System Migration Service

    In some scenarios it would be useful to suppress the automatic registration of these SPNs. For example, I manage several secure networks which include Windows Server 2016 VMs which utilise Virtualization Based Security features. These VMs require the Hyper-V role to be installed as a dependency of VBS but do not host any VMs. There is no valid scenario…

  15. Provide native conversion tools

    For conversion from vmdk to Hyper-V we had to use external tools.
    It is weird that there are no Microsoft tools to provide seamless conversion to Hyper-V. Instead one must rely on 3rd party products.
    Provide solutions integrated into VMM to convert and kind of .vmdk or .vdi hasslefree into new Hyper-V guest.

  16. Provide conversion tool to convert generation 1 guests into generation 2 guests

    When converting exisiting VMware guests into Hyper-V guests we are not aware of any tool to offer conversion into generation 2 guests.
    Hence we are sitting here with generation 1 guests and there is no tool to convert them into generation 2. We are aware ot a Powershell script but this has failed on us.
    Provide conversion from within VMM to convert generation 1 guests in generation 2 guests.

  17. VMNetworkAdapter: Allow arp out for multicast mac addresses (even if MacAddressSpoofing is off)

    VMNetworkAdapter on vSwitch: Please allow arp out for multicast mac addresses even if MacAddressSpoofing is off (or add another option to do so). It's not spoofing telling the switch about a multicast mac - how else would it know about it? It belongs to everyone! NLB is nice L4 active/active redundancy but relies on multicast or unicast flood. Multicast traffic is always received on default queue (understandable as multicast mac is not associated with vNic and can't be allocated a VMQ - but, default queue has finite cpu scalability). If you have MacAddressSpoofing enabled, then Windows unfortunately does not allocate…

    performance is very big concern in virtualization platform and some standard templates should be available in Perfmon for access the Reports.

  20. Delegate VM Managers

    I love you MS, but it's rediculous that i can't delegate hypervisor access (console, vm settings, etc) to the person responsible for that VM. AFAIK every major hypervisor natively allows this but yours.
