I recently installed Oracle Virtualbox from their website on Xubuntu 15.04 64-bit. Specifically, Virtualbox 5.0.4. However, when I try to install a virtual machine, it only gives me the option to install a 32-bit OS (as seen below). Is there a way to allow 64-bit OSes?
Ubuntu – Virtualbox has no 64-bit options

This is normal if your CPU does not have hardware support for virtualization (Intel VT-x or AMD-v). Older 64-bit CPUs may not support this.
