Just tested successfully not only on Windows client OS but also Windows Server 2016 and 2019 with newest patch level.
CPU load is shown again > 0%.
Is there a fix for Windows 2025 Server to show CPU load of HyperV VM

As lot of people found out - there is a bug in Windows Server 2025. Even if a VM is under full load - the Hyper-V does allways shos 0% CPU. Result (seems to be) that the CPU stay in slow GHz - witch ist not what one can expect from a Server.
I verified with HPE 2 XENON Gold 512GB RAM.

It's as dumb as someone asking: do you think it's going to rain in an hour?
And Ian Xue responds with: look back at the statistics 10 years ago, make sure your window is clean, and you have a spare raincoat.and Microsoft is these days filled with these absolute STUPID dumb answers which are no answers... but look-alike answers, so the get commission, or a bonus or whatever benefit.
Because they don't even bother to dive into the question.
They just think, well.. my boss or whoever, have no idea anyway about the tech specs, so i just blur out some generic stuff.
shamefull

Lohkamp 81 Reputation points2025-02-11T09:10:18.4666667+00:00 The same for at least many week now with Windows 11 Pro or Enterprise 24H2, newest patch level: all Hyper-V VMs running fine on a lot of hosts but all show 0 % CPU load in Hyper-V-Manager (for all guests, Windows, Ubuntu, Debian,...) even when I run a 7zip benchmark which shows 100 % CPU load in the task manager within the VM. All hosts have AMD Ryzen CPUs but I read that the same occurs on Intel hosts.

Dmitry Kirushev 56 Reputation points2025-02-11T18:26:44.99+00:00 It’s frustrating to see the same disheartening situation in the Windows Admin Center. The CPU usage is stubbornly stuck at 0% on all VMs running on Windows Server 2025 and Windows 11 24H2. It’s like watching a pot that never boils.
I’m anxiously waiting for a patch, as my home LAB depends on Windows 11 24H2. It’s absolutely crucial for me, and this issue is seriously holding me back.

2025-02-11T19:37:54.9366667+00:00 I am extremely disappointed and very angry. The February update still hasn't resolved the issue!
Installed:
2025-02 Cumulative Update for Microsoft server operating system version 24H2 for x64-based Systems (KB5051987) on Server and
2025-02 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5051987) on Windows 11 24H2. -

RamboNo 5 10 Reputation points2025-03-08T08:05:43.3233333+00:00 I have exactly the same problem with Server 2025 on a Ryzen 5 7600 CPU. 0% CPU utilization all the time in Hyper-V Manager for each VM (Windows, Debian, etc.)
At the moment it is not yet a problem in our company, but in the future more users will access it and then it could cause significant problems if the VMs are not running at full performance.
