Can not run Windows VMs after update

Post by iam-py-test »

After updating from version 6.1.30 to version 6.1.34 (also tried 32), my Windows VMs crash and show this message:
vbx error.png
vbx error.png (12.69 KiB) Viewed 971 times
Happens on both 10 and 11 VMs. I had an issue with my Linux VM, but I am unsure if it is related.
All but one of my VMs are stored on an external drive, but I don't think the issue is related.
I attached the logs in a ZIP file as they were too big to upload on their own.
Sorry if I did any of this wrong.
Thank you.

Your log contains these lines.

00:00:05.844846 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

This indicates that something is preventing VirtualBox from accessing hardware virtualization. The most likely cause is that the Windows hypervisor is loaded.

If you cannot disable Hyper-V then try the latest 6.1.35 test build.
