Of course VMDK file is not really a disk and virtual machine is not 
really a machine. With VMWare, it is possible to use LVM logical volume 
instead of file, it's called "RDM", which stands for "raw disk mapping". 
Essentially, it's a real LUN is mapped to the virtual machine to use it. 
However, I am using a desktop class machine and unfortunately don't have 
an EMC VMAX in my living room. It is very unlikely that I will ever have 
a full fledged SAN, so I am stuck with the files. VirtualBox cannot do 
RDM, but it doesn't really matter. 
As for the thin provisioning (a growing disk), I avoid it like a plague 
because it slows things down. My RDBMS/VM server is not a really fast 
machine and I am trying to get a decent performance out of it. That is 
why I defragment my file systems and use XFS.
