If you get the error installing Ubuntu Linux: – “This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot – please use a kernel appropriate for your CPU” it means you are trying to install a 64bit version of ubuntu on the virtual machine.
When you go to the ubuntu website the default CD to download for server is the 64bit version. Programs like Windows Virtual PC can not have 64bit Virtual Hosts. Go back to the website and download the x386 version.
Just be thankful you weren’t the only one that doesn’t read the download forms on the website 😉
