Ok, I have the most recent version of virtualbox installed, my computer (HP) has an AMD A10, 64bit Windows 10 OS and 6Gb RAM.
I created a virtual machine with Windows 7, there I wanted to create a new virtual machine (a VM2 in a VM1), but I cant run it because I have no virtualization enabled in the VM1.
ok, so I checked the VM1 configuration and the virtualization is enabled in the virtualbox settings. I've tried with all the Paravirtualization interfaces and always having the Hardware Virtualization enabled (VT-x and AMD-V).
I really don't know why this is happening if this is all suposed to be enabled and there arent documentations of similar issues.
I tried changing the number of CPUs used by the VM1 and all the interfaces.

I seach for 2 days and nothing worked for me.. then i find the solution:
The problem is in Windows 10... u need to disable Hyper-V Manager ...
1) make sure in your BIOS cpu virtualization is enable.
2) open your CMD as administrator
3) in your desktop folder type
