Which do I need, i386 or AMD 64

[alfred_bowman]

I have downloaded Ubuntu 8.10 for installation on a PC with an AMD Athlon X2 64 CPU. I intend to install Windows XP Home in a VM created by VirtualBox. This is what the VirtualBox download page says:

"The package architecture has to match the Linux kernel architecture, that is, if you are running a 64-bit kernel, install the appropriate AMD64 package (it does not matter if you have an Intel or an AMD CPU). Mixed installations (e.g. Debian/Lenny ships an AMD64 kernel with 32-bit packages) are not supported. To install VirtualBox anyway you need to setup a 64-bit chroot environment.

Note: The VirtualBox 2.1.0 deb/rpm packages do not properly unregister from dkms before the package is removed / upgraded. Please have a look at our FAQ for further details.

Please choose the appropriate package for your Linux distribution:

* Ubuntu 8.10 ("Intrepid Ibex") i386 | AMD64"

Which version should I download?

BTW: A prior page indicated that the PUEL version would be downloaded. This matters as I require full USB support.

If you are using a 64-bit host OS, download the 64-bit aka AMD64 version of VirtualBox.

To determine if you are using 64-bit Ubuntu, execute the following in a terminal :
uname -m

The output will be x86_64 if your host OS is 64-bit.
