Space used by local virtual disk less than expected

I noticed when installing an LDOM through Ops Center on local storage, that the virtual disk appears to initially use far less space than its allocated size.
For example, an LDOM with a 50GB vdisk appears as 50GB in "ls -l":

# ls -l /guests/5e9bf7f8-511f-47cc-bfb2-7a08e1b8245e/virtdisk/data
-rwx------   1 root     sys      53687091200 Feb 22 16:36 /guests/5e9bf7f8-511f-47cc-bfb2-7a08e1b8245e/virtdisk/data

But "zfs list" and "du" show it using a fraction of the space:

# du -sh /guests/5e9bf7f8-511f-47cc-bfb2-7a08e1b8245e/virtdisk/data

Howdy, Stranger!
