You can enable this by going to the BIOS settings, usually when you start your computer, press F12 and then it will go into BIOS mode, there you can find the config setting ' Virtualization Technology' and vt-d feature.

The next thing you need to do is to enable hardware virtualization. But one necessary condition is that you have a 64 bit processor. If you use the 'Create VM' wizard of the VirtualBox graphical user interface (see the section called “Creating your first virtual machine”), VirtualBox will automatically use the correct settings for each selected 64-bit operating system type.īased on the documentation, VirtualBox allows to install 64 bit OS even if you have a 32 bit host OS installed. In addition, for 64-bit Windows guests, you should make sure that the VM uses the Intel networking device, since there is no 64-bit driver support for the AMD PCNet card see the section called “Virtual networking hardware”. See the section called “' Advanced' tab”. This is especially true for 64-bit Windows VMs. On any host, you should enable the I/O APIC for virtual machines that you intend to use in 64-bit mode. On 64-bit hosts (which typically come with hardware virtualization support), 64-bit guest operating systems are always supported regardless of settings, so you can simply install a 64-bit operating system in the guest. Since supporting 64 bits on 32-bit hosts incurs additional overhead, VirtualBox only enables this support upon explicit request.

If you want to use 64-bit guest support on a 32-bit host operating system, you must also select a 64-bit operating system for the particular VM. You must enable hardware virtualization for the particular VM for which you want 64-bit support software virtualization is not supported for 64-bit VMs. You need a 64-bit processor with hardware virtualization support (see the section called “ Hardware vs. VirtualBox supports 64-bit guest operating systems, even on 32-bit host operating systems, provided that the following conditions are met: Here is the official documentation about 64 bit OS: To allow installing 64 bit OS on VirtualBox. But sometimes, 64 bit OS is wanted for specific uses such as running platform specific tests. By default, VirtualBox only allows to install 32 bit OS on it.
