Virtualbox won't import appliance

[Jim Byrnes]

I have Virtualbox setup and running on a 32 bit system with XP as a 
guest.  Everything is working well and now I want to transfer it to a 
new 64 bit system I am setting up.

My research indicated that the package in the repository probably won't 
run on my 64 bit system so I downloaded the amd64.deb package from Sun.I 
used dpkg to install it and now have it up and running.

I used Virtualbox on the 32 bit system to export the XP guest. It 
produced XP.ovf and XP.vmdk which I  transferred  to my new machine. 
When I try to import it on the Virtualbox there the inport wizzrd sees 
the XP.ovf file but when I select it and click next I get a pop up 
saying "failed to import appliance"

Can anyone who has done this please give me guidence?

Thanks,  Jim
