virtualization enabled in BIOS but not seen in virtualbox

Question

Someone know why I can't see nested VT-x option in virtualbox ?

my setup is:

OS : windows 10 Home.
CPU : i7-4510U.
Virtualization : enabled in BIOS.

I tried disabling windows features Plateform virtual Machine and Hypervisor But nothing is working. The command systeminfo on CMD says yes for all Hyper-v options.

VT-x is required by Android emulator which I want to start on a ubutu virtual machine.

Do you have another virtualizing app running? Try removing those if so. Make sure Hyper-V is disable in Windows Features. — John, Sep 25 '21 at 20:33
but Hyper-v does not exist in windows 10 family although the command above mentioned displays Hyper-v things. Also i have a fresh installation with only Chrome and virtualbox. — miracle genuis, Sep 25 '21 at 20:37
@miraclegenuis - Hyper-V absolutely is a feature of Windows 10, Windows 10 Professional, if your running Windows 10 Home it does not exist. However, that doesn’t stop you from enabling VT-x — Ramhound, Sep 25 '21 at 21:02
@Ramhound I updated my post, it is windows 10 Home not Family (which it does not exist). VT-x is indeed activated (shown in Task manager) But virtualbox not detecting it. — miracle genuis, Sep 25 '21 at 21:13

I resolved the same yesterday. Shut down the VM (save doesn't work) and VirtualBox, and on the command line:

VBoxManage modifyvm vm-name --nested-hw-virt on

It should now be enabled in the VM settings.

I already tried it out but without the "on" keywords as the documentation [here](https://docs.oracle.com/en/virtualization/virtualbox/6.0/admin/nested-virt.html) leads me to undestand. Anyway thank you a lot that the solution . – miracle genuis Sep 25 '21 at 23:27
@miraclegenuis It's needed :-) – Peregrino69 Sep 25 '21 at 23:30
yes it was better if vboxmanage can tell one that this option needs on/off arguments. Thank you again i waste a lot of time on it. – miracle genuis Sep 25 '21 at 23:34
Me too, mate, me too... :-D – Peregrino69 Sep 25 '21 at 23:35
