  • You seriously need to talk about what host os version and arch, and system you are using to get a more complete answer. – Journeyman Geek Nov 17 '13 at 06:18

This Kernel requires a x86-64 CPU. Unable to boot.

That means you are trying to install 64-bit server in a 32-bit CPU. The Ubuntu 13.10 32-bit download link not placed in main download page.

You can get Ubuntu 13.10 server 32-bit here

Hope that helps you.

Under Settings / General / Basic (tab), what Ubuntu version did you specify? It should be Ubuntu (64 bit). If it's just Ubuntu, this would be one reason for the error. Also there's a possibility that you need to turn on, in your BIOS settings, Intel Virtualization Technology (IVT) or AMD-V depending.
