I am trying to start Windows 7 (64-bit) guest VM, but I am getting this error. I tried to google about that, but no results. Other guest VM works fine (like Ubuntu).
Code: Select all
/TM/TSCTiedToExecution is not supported in NEM mode! (VERR_INVALID_PARAMETER).
Result Code:
E_FAIL (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
VirtualBox 6.1.12r139181 (Qt5.6.2)
Windows 10 (2004) 64-bit with WSL2
AMD Ryzen 9 3900X with virtualization enabled

I suspect that Hyper-V is enabled. Go through posts 2 & 3 in
I have a 64bit host, but can't install 64bit guests.
If that does not help, start the guest from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.
Right-click the guest in the main Virtualbox window's guest 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.

Hyper-V is disabled/unchecked in "Turn Windows features on or off".
I can't start guest VM as it closes quickly and displays that error.
Log is in the attachment.

Hyper-V is still enabled. Other things in Windows 10 besides the official virtualizer use Hyper-V.

Thanks!
I entered this command in Command Prompt:
Code: Select all
bcdedit /set hypervisorlaunchtype off
and restarted PC, then I was able to start this guest VM, everything seems to be fine.
Well, WSL2 doesn't work anymore because of that... So it's not possible to use both at same time?

Great! Glad you're up and running.

Correct. WSL2 requires Hyper-V. It's either-or for now. See the "tenforums" link in the tutorial for how to set up a boot click-switch that can turn Hyper-V on or off at each boot.
