Weird.  It's strange given the guest also isn't paused...

I noticed that you had the physical CD-ROM drive mapped as the guests virtual 
CDROM.  Could you try taking that out, please?  I'm not at all convinced 
that's the source of the problem but I do remember having problems when I 
tried to do that myself (that was for an installation of Windows - I ended up 
ripping the CD to an ISO and using that as the virtual CD drive!)

Cheers,
Mark
