Actually, there is a way to make it handle partitions. When connecting a
"whole partition" device, nbd automatically creates subdevices for each 
partition,
named /dev/nbd0p1 (for first partition), /dev/nbd0p2, /dev/nbd0p3, ...

So you can do:
  qemu-nbd  -c /dev/nbd0 ~/kvm/c.img

or, depending on your distribution:
  kvm-nbd  -c /dev/nbd0 ~/kvm/c.img

... and then access it as follows:

  mdir -i /dev/nbd0p1 ::
