Question ASrock B850M Pro-A Wifi (AMD) – how to set virtualization active in BIOS

[colettina]

I am just trying to use Oracle Virtual Box. But only the VBox-Mnager can be started. And after that, I cannot add any of my Virtual Machines to it. When I try, VBox-Manager will freeze.

I have had this effect already on another computer and there the virtualization in BIOS was not set active.

I have searched the entire AMD-BIOS of this board and I did not find any setting for AMD virtualization. Is it active by default?

I have searched the entire AMD-BIOS of this board and I did not find any setting for AMD virtualization.
Can you see any entry for SVM? Should be nested inside Advanced>AMD CBS>CPU Common Options.

Thank you for your quick reply. I have found this item quickly now. The settings were "auto" and the SVM-lock also has been "auto".
These settings would allow, that a virtualization software could activate or deactivate these features. I suppose, that VirtualBox cannot activate it. So I have put both "activated.

If I would not activate SVM-lock after havin activated SVM, then it could be deactivated again by some software. Locking means, the SVM acitivation cannot be changed by any software.

Thank you!
