[one-users] empty qcow2 datablock image with preallocation

[Ruben S. Montero]

This cannot be specified through the interface CLI or sunstone (just
fstype, an size).

However you can easily add it to the filesystem creation script. Look for
scrtips_common.sh and mkfs_command, around line 311.


Cheers
