  1. 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. It would be nice if in Linux unused but committed memory would not count to Windows used memory

    It would be nice if this memory was counted in the host as committed but unused memory ('Available' in Task Manager).

    Currently hv_balloon tells Windows it requires all the Committed_AS memory. Which is fine to do, but in Windows Task Manager this unused memory (not used by Linux) is then shown as 'In Use' memory.

    I'm unsure if this unused but committed memory will push out cache and applications on the host side. So it *might* be purely cosmetic, but it would be good to check in the Windows kernel's Hyper-V parts. Or maybe put this empty memory through the…

  4. Support for Microsoft Hosted Network Virtual Adapter

    Allow a Virtual Switch to connect to the Microsoft Hosted Network Virtual Adapter. Other virtualization products allow this; Hyper-V doesn't. This is a severe limitation.

  5. VMconnect full screen does not display connection bar when DPI higher than 100% on v1607 14393

    VMconnect full screen does not display connection bar when DPI higher than 100% on v1607 14393(issue exists with both the server and the client's VMconnection). Only non-enhanced session affected, enhanced session mode is not affected.

    It's really inconvenient to use a virtual machine on a full screen at a DPI higher than 100%.

    Even with the latest updates installed (as of April 2019), the problem persists

    I hope this issue can be fixed in time, at least for now v1607 14393 Server and Client LTSB versions are still in the mainstream support.

    How to repo on v1607 14393:

    1. Set…

  6. Allow automatic stop action setting to be changed/applied while a VM is running

    The ability to change the stop action of VM without having to power it off.
    Or at least allow it to be prestaged for it to do it on a VM reboot

  7. PIN and virtual smart card logon for Enhanced Session Mode (ESM)

    PIN and virtual smart card logon for Enhanced Session Mode (ESM) in vmconnect.exe. This would be a benefit in PAW/SAW scenarios, as well as local dev, to facilitate logons to local HyperV guests.

  9. 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.

  10. Nested Virtualization Support for AMD CPUs

    Currently nested virtualization is only supported on Intel CPUs. Please add support on AMD CPUs. At the very least Epyc CPUs, but older Opteron CPU support would be nice as well.

  11. Show Topology for host,VM , networking , storage(suchas CSV, SOFS share, local vol) relationship

    Please provide a topology tool in mmc or web(WAC), for show the relationship on following view:
    1 how host connect networking and storage
    This is a great help for many scenario: troubleshooting underlayer problem , tuning performance, even help of planning available or capacity expand.
    2 how VMs connect virtual network and data space
    This is a great help for many scenario: troubleshooting VM-level problem, hardware maintenance planning etc.
    3 how VMs placed to hosts
    scenario: VM resource placement optimizing, VM role high available planning or capability expand planning, host maintenance planning.

  13. Hyper-V: Allow Replication also if one of the disks are physical

    Actually i can't enable replication if one disk is a physical disk, also if i don't plan to enable replication for the physical disk. I would prefer to enable replication without this physical disk, but for the other virtual disks.
    It seem to be only an block in the Hyper-V Manager, so it would be great to move this check for blocking the replication after the user was able to select the disk to be replicated.
    Only if here the physical disk is still enabled, block the replication with the corresponding error message:
    "Replication can't be activated. Replication can't activated…

  14. Set VHD(X) storage as persistent (immune to Revert)

    There currently is no way to add a VHD(X) to a virtual machine so that changes will not roll back after a Revert. One could use a network drive as a workaround, but this is not always feasible. Therefore, an option on a per-disk basis would be desirable.

  16. copy and paste

    the enhanced session thing is not easy to get right and breaks easily plus it seems a heavy weight way to get this to work

  17. Single Backup of VM's with Off State

    How about adding a new Boolean attribute to VM's to record whether it has been backed up by the VM host's Backup Server since it enter the "Off" state thus eliminating the need to back it up again. The Backup Server would set the attribute state to "Yes" once it has been backed up in the "Off" state. Once the VM enters the "Running" state the attribute would be reset to "No".

  19. 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.

  20. Virtual IPMI device for Nested Hypervisors
