Well, indeed, it would seem that the general definition of distributed
filesystem == network filesystem.
I guess (and I am admittedly biased) I just feel like the bar on
"distributed" filesystems has been raised so that a distributed
filesystem is a network filesystem which is truly distributed amongst
more than one "server" node. It doesn't seem the industry is
recognizing this (yet) however.
VirtualBox is supposed to emulate desktop PC not full blown
hiper-complicated machine
Hiper-complicated machine? "Hiper-complicated" machines, a.k.a.
super-computers, today, are frequently built using commodity "PC"s, so
modelling a supercomputer with a few VMs is a perfectly viable use-case.
The distinction is not as black and white as you might want it to be.
Agreed :-)
If it is necessary to access one physical disk form few virtual machines
ATA over Ethernet it is way to go

Not it's not. A VMDK virtual disk does just fine. Perfectly in fact.
AFAIK VMDK is proprietary VMware(Never used :-) file format not fully
supported by VBox .
I doubt it is possible to achieve "sharing "physical-virtual" disk"
between few VBox machine instances this way or I'm wrong :-)
I bet it is possible via ATA over Ethernet :-)
