Sometimes Docker fails silently to enable Hyper V

Expected behavior

Docker should enable Hyper V when I click “Install & Restart” upon the Hyper V prompt.
It should tell me in case it was unable to enable Hyper V.

Actual behavior

Some time passes without a progress indicator.
An error message will pop up which says some constructor belonging to Hyper V could not be found.
(Instead it should say: “Hey, I could not enable Hyper V for you. Here are the manual steps to do it yourself.”)


  • Windows 10 Pro
  • Docker Version 1.11.1-beta12 (build: 3073)

Steps to reproduce the behavior

  1. Install Docker
  2. Let it enable Hyper V & Restart (works)
  3. Uninstall Docker
  4. Disable Hyper V via Windows Feature Settings
  5. Install Docker and let it try to enable Hyper V (did not work)

(I know this is some weird kind of edge case but I wanted to report it anyway, maybe it is useful.
Fix: I had to enable Hyper V in the Windows Feature settings myself.)

Same error in Windows 10 when installing Docker for Windows. See screenshot.

Thanks for reporting, we’re working on a fix.

Worked for us, thanks

Had the same issue. I enabled HyperV manually and docker ran fine. But it says it’s supposed to be done by the software.

Had the same, the issue for me was the virtualization was disabled in the bios disallowing the activation of Hypersupervisor
