[Solved] "A critical error has occured while running the virtual machine"

Hi all,

I use a linux VM and always save state/resume state on it. Lately every time I resume state I get the below message:

The only thing I've done recently is install WSL2 (I'm fairly sure it's got something to do with this..) and install the latest AMD GPU drivers. I've done some googling about WSL and vbox but they seem to be issues relating to booting the machine. Does anyone have any ideas what I can do to resolve this?

You'll notice that the error picture says to post something... see how it says to provide the contents of a certain log file? But before you do, lets see if this can be fixed quicker:


Please right-click the VM in the main Virtualbox window's VM list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled and needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don't find that text, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

Thanks, that seems to have been the issue.
