Fedora 9 and Vista Ultimate Running Virtual Machine 2007 in x64 Environment Fails
I have been playing with Linux distribution Fedora 9. However, I cannot get it to install in my Microsoft Virtual Machine 2007 running in x64 Windows Vista Ultimate SP1. The CPU is a dual core socket 939 Opteron on an Nforce4 motherboard.
The error I am recieving is i1586 core does not exist. You better believe it doesn't. See the picture below.

I did find several posts in forums that state older x64 processors would be discovered as x32 virtual environments. What makes it really odd is they suggest running the i386 edition of Fedora 9.
You can get fedora 9 here: http://fedoraproject.org/get-fedora.html

Hopefully, i'll be able to post that the i386 edition works.
