My system (see att 1 - system)

While trying to install Solaris 11.3 in Virtualbox 6.1.26_Ubuntu r145957 I have an error message in settings: "The hardware virtualization is enabled in the Acceleration section of the system page although it is not supported by the host system. It should be disabled in order to start the virtual system."

I have disabled the offending box but the message doesn't clear. I have "reset all warnings" under file menu, uninstalled and reinstalled VB (both repository and Oracle types), checked the BIOS, looked out the window, etc. but nothing clears the warning. It still says "Invalid settings detected"
Can some one tell me what I'm missing?

(Is there a way to list these pics inline?)
Thank you!

Since this thread is now marked "Solved," could you post your solution? It might help someone else with the same problem.

Thanks.

I found an SVM setting in BIOS overclock controls, per some elses suggestion on another forum
