I'm having trouble with VirtualBox within Ubuntu. I want to create a 64-bit virtual machine, but VB only gives me 32-bit options (see screenshot). I installed VirtualBox on macOS, and it works fine. However, when I installed VB within Ubuntu I got this problem.
In fact, I wanted to install
gnome-software (with Virtualbox) on Ubuntu in following this YouTube tutorial, but it is not possible so far.
I have a Macbook Pro (Mid-2012, 13-inch), and Ubuntu 64-bit with installed with VirtualBox
The problem seems to be the Vt/x is disabled. I thought it was the one on the OS X. According to the Apple Support, it couldn't be modified from OS X. So we have to enable from VB.
Question : Could anyone be able to tell me how to enable virtualization from VB?
P.S. It is a bit weird, but I installed Ubuntu with VB on macOS, and now I want to install gnome-software with VB within Ubuntu.
