Virtualbox guest complains system is only 32 bit

I'm trying to use VirtualBox on a 64 bit host (Fedora 12), and install a 64 bit suse guest. I have VirtualBox installed just fine on the host, but when I try to launch the guest (booting from an iso) I get the message "This is a 32-bit computer. You cannot use 64-bit software on it".

One thing to note, this host, while 64 bit, does not have the AMD-V extensions. (Not sure if this matters or not). I do however have another 64 bit host with the AMD-V extensions that runs a 64 bit guest just fine.

I confirmed `uname -m` on the host reports "x86_64". I also did a `file /usr/lib/virtualbox/VirtualBox` just to make sure I got the 64 bit version of VirtualBox

Any ideas on why the guest os would think the host is 32 bit when it should be a 64 bit system? Thanks for your help!

Are you certain that it is complaining about your host not being 32 bit? Or is it complaining that your vm is configured for 32bit, but your OS is 64 bit?
