I seem to have encountered an odd / unexpected problem here. I have a WIndows 7 64 bit virtual machine prepared on my desktop system, which an ubuntu 11.10 64 bit box, running on an iCore 7 CPU. I'm trying to move this virtual machine to my server, which is an ubuntu 10.04.3 LTS 64 bit box, running on a Xeon CPU. I'm running the same version of virtualbox on both systems.
But, on the Xeon box, the Windows 7 64 bit VM just won't boot up.
I tried to have it repaired by booting the windows install DVD, but it won't repair it. I tried to re-install Windows 7 64 bit into a new VM on the Xeon box, but during the install, at the first reboot it says the computer is not compatible. Finally, I tried and succeeded in installing Windows 7 32 bit into t a new VM on the Xeon box.
But, I'd really like to get the 64 bit version running there. Are there any known issues with running 64 bit guest OSs, particularly Windows 7, on a Linux-based 64 bit Xeon host?

PS: some additional information
first, about the iCore 7 machine, where the 64 bit Windows 7 guest runs fine:
