I'm having the same problem whiteb was having... importing gives me an error "cannot unregister the machine because it has 2 medium attachments".
If I add the disk image manually to the imported machine, I get the same result as whiteb about the DMA transfer failing (exactly the same result)
Any tips? I've tried ATA=nodma and ATA=nopci, and get the error "device is in invalid state". I've re-expanded the disk image to make sure that something hadn't corrupted the image, but no joy on that front.
Tried the image in VMWare Fusion too.
I'm running MacOS 10.6.2, Virtual box 3.1.2 r56127...
