Linux – Installing 64 bit CentOS using VirtualBox

64-bitcentoslinuxvirtualboxwindows 8.1

I downloaded VirtualBox to a windows 8.1 machine by selecting the Windows (32-bit/64-bit) installer option at this link on the Oracle web ste. But when I try to create a new Virtual Machine using resulting VirtualBox, all of the Linux options are 32 bit.

How can I get VirtualBox to set up a 64 bit CentOS 7 virtual machine? Do I need to download a different installer? Or is the problem that I am not using this installer correctly?

Assuming you have a 64-bit CPU, then one would need to enable VT-x/AMD-v in the BIOS of the host computer. After enabling the virtualization features in the BIOS, VirtualBox can be obtained from www.virtualbox.org.

VirtualBox 4.3.28 for Windows hosts x86/amd64
Also install the Extension Pack after installing VirtualBox.

I don't know if the feature for installing a 64-bit guest will just appear in VirtualBox after enabling virtualization. Maybe a re-install might be needed.

In your screenshot, the host and the guest have the same IP. That doesn't seem right. If you've set your VM to use NAT, it will receive its own IP address. Port forwarding shouldn't be needed (unless you want to be able to connect to a service inside your VM through your hosts networking interface).

To determine your local IP address, run the following command inside a shell on your VM:

ip a

I don't think you'll be able to get clipboard sharing to work without the additions installed. Can you manually run the VBoxLinuxAdditions.run file and see if it will either install or give you a proper error?
