Error starting Ubuntu guest on Windows host

[hallmichaelr]

Hi all,

I've been having mega trouble with my Ubuntu VM today, although it's been working perfectly for a long time. Upon startup the machine just stops. Logs and image attached.

Any help would be gratefully appreciated.

The zip file is empty, it contains no log file.

Before you post a new zip, open your log file and search for:

Attempting fall back to NEM

If this text is in the log file, then Hyper-V is enabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

Wow thanks! That's exactly it. Disabled Hyper-V and my VM is now happy again.

The issue seems to be that I attempted an install of Docker on my Host to troubleshoot an issue, and that a) didn't work and b) broke Virtualbox.

Great! Glad you're up and running.
