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

modify the docker-compose.yml file with this and it should work, well it works for me

version: "3"
services:
  windows:
    image: dockurr/windows
    container_name: windows
    environment:
      KVM: "N"  # Disable KVM acceleration
    cap_add:
      - NET_ADMIN
    ports:
      - 8006:8006
      - 3389:3389/tcp
      - 3389:3389/udp
    stop_grace_period: 2m
    restart: on-failure

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.

This work for me in a M1, thanks

@fredpena Yes but with it will run in slow-motion, because it needs to emulate a x64 cpu on arm64 hardware. The only real solution is to use the windows-arm container which has the arm64 version of Windows. But it will still be slow because I havent added support for HVF (the macOS variant of KVM) yet.

I'm seeing it to be super slow, now that I'm using it. Do you have any idea when HVF will be available?

[kroese]

@fredpena I dont know if it will ever be available. Because the QEMU version for Debian is compiled without this feature. And even if I go through all the trouble to compile a custom version myself, I have no macOS hardware to perform any testing if it even works. So I guess its better to wait until somebody else adds this feature for us.
