services:
  windows:
    image: dockurr/windows
    container_name: windows
    environment:
      KVM: "N"  # Disable KVM acceleration
    cap_add:

What CPU do you have?

[pipuwong]

AMD EPYC 7282 16-Core Processor

[kroese]

As far as I can find that CPU supports hardware virtualization just fine, so KVM should be no problem for this processor.

What OS are you using? Because either the OS did not install the KVM software or otherwise you have the virtualization features of your processor disabled in the BIOS.

i have same error and use ubuntu server

[HenryZhang-ZHY]

Never run it with docker-desktop!
I had the same issue, after I read this post, I realized I should run it with local docker engine, instead of docker-desktop.

Have anyone solved it? I'm using Windows 10 system, with an i7-10700 CPU, and hardware virtualization is enabled. I'm encountering the same issue.
