Being one of those that is going through this headache right now (have something to check in BIOS, but its a remote server, so haven't been able to yet), the above pointer / url is very much  useless, unfortunately … I've read it, repeatedly, and it happily refers you to the GUI …

The only thing that I found on that URL refers to "you should enable the I/O APIC for virtual machines that you intend to use in 64-bit mode" … which David stated above that he has tried …

So … is there something specific at that URL (beyond the I/O APIC that David did try) that he and I (and potentially others) have both missed for this?
