Try the current qemy-img info on a raw file you will be surprised of the 
results.
This field also can have an "unavailable" value.

example result with unpatched qemu-img:

address@hidden:~/qemu$ qemu-img info truc1.raw 
image: truc1.raw
file format: raw
virtual size: 1.0G (1073741824 bytes)
disk size: 776M

disk size is actual-size.
