Hi,
I'm trying to install kali on virtual box.
I'm using an HP Windows 10 machine.
I've checked BIOS and virtualization is enabled.
I've downloaded kali 64 bit version for virtual box: kali-linux-2021.3-virtualbox-amd64
I've downloaded and installed Oracle VM virtual box.
I've tried to follow the istruction posted here https://www.kali.org/docs/virtualiza...lbox-guest-vm/ but I don't understand the last step where I've to find the iso image.
I've tried just double click on kali-linux-2021.3-virtualbox-amd64 and it seem works properly but at the end, when I try to start the VM I get the following error:

Apertura di una sessione per la Macchina Virtuale Kali-Linux-2021.3-vbox-amd64 non riuscita.


Call to NEMR0InitVMPart2 failed: VERR_NEM_INIT_FAILED (VERR_NEM_VM_CREATE_FAILED).
