I have another question, is it necessary to activate Windows 11 to run docker windows in virtualbox

It’s been 7 years since I used VirtualBox on Windows the last time. The green turtle you see in the status bar of the vm is the reason I stopped using VirtualBox and the reason you experience what you experience.

The green turtle indicates that VirtualBox is using the Hyper-V compatibility mode, which prevents nested virtualization (and slows down the vm by magnitudes).

You can either run a Linux vm in Virtualbox (or in a WSL2 distribution) and install docker-ce on it to run containers.
Though, i would recommend running Docker Desktop on the Windows host directly.

Update: I found a forums post in the VBox forum about how to get rid of the green turtle: HMR3Init: Attempting fall back to NEM (Hyper-V is active) - virtualbox.org.
