Why won't Homestead start in a virtual machine?

Question

virtual box

Initial data:

• Main OS on the computer: Windows 7
  
• Installed on VirtualBox Ubuntu 16.04 64-bit with "System > Acceleration > Hardware Virtualization > Enable VT-x/AMD-V" option enabled
  
• VirtualBox 5.1, Vagrant 1.8.5 installed inside Ubuntu
  
• Installing Homestead inside Ubuntu
  

Those. I'm trying inside Ubuntu, running as a virtual machine, to run a virtual machine through vagrant.
Homestead was installed following this instruction https://laravel.com/docs/5.3/homestead
There are no errors in the Homestead.yaml settings.
After the vagrant up command, the virtual machine is deployed, which fails with an error:

"Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value."

Everywhere they write that the error is in the non-enabled VT-x virtualization option, but it does exist!
Or is it not possible to run virtual machines nested?

Have you decided to play matryoshka? Are you trying to install a virtual machine inside a virtulaca?
Just install vagrant for windows and use homestead from WINDOWS.
