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.

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.

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.

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.

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.

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.

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?

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

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.

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.

We can play open with all people i can run a lobby which u call server and we can point out the kinks with live people so there are no lagouts or glitches i take NBA live to heart it is the best game created as do my peers plz let us help thanks Harold Millican 1 281 848 8675 contact me at anytime

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.

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.

Hi Team,

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

supporto WPHX from Windows Server 2019 to run Windows 10 nested Hyper-v for Android Emulator

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.
