Nested VT-X/AMD-V activate

Post by ognif »

Since this weekend I cannot start any VM that has "Nested VT-X/AMD-V activate" enabled. The option itself is greyed out.
This confuses me, because on Friday everything worked welll. I remember there was a Windows10 Update.

My CPU is a RYZEN 7 Pro on a Thinkpad T14s Notebook.

Anybody have the same issue and can help me out with it?

Provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.
