Can't get any Win VM to run on Win11 host..??

[angelleye]

I have a Win10 VM that I was running on my Win10 host with no issues.

I have updated my host to Win11, and now I can't get the original Win10 to load. I also cannot get a fresh install of a new VM to load.

In both cases the Windows start-up logo spinner shows up, but it lags extremely slowly, and eventually stalls and will not move forward at all.

I'm running the latest version of VirtualBox. Not sure how to troubleshoot this or how to proceed.

Any information on this would be greatly appreciated. Thanks!

Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

It sounds like you enabled Hyper-v during the upgrade. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).
