OK, if you had ZFS (Solaris, and others) you could use ZFS snapshot
for this purpose. Search the Internet, Oracle definitely have
whitepaper on this use and VirtualBox.

Hi there,
my scenario is the following: I have a classroom with two dozens
of Windows 7 machines.
I would like to create a read-only virtual disk that is placed on
a network drive. That disk would contain a standard install of
Fedora 20.
Now I would like to have an overlay filesystem that is based on
the virtual disk above, and, per user we would have the
difference. Since I would not encourage the installation of large
packages, that overlay filesystems would contain only
configuration modifications mostly. I would share these diffs
through Samba to have password protection.
Is this doable with Virtualbox? How? Would it make acceptable
speeds for running basic services like httpd and mysqld?
Cheers

Peter, that is exactly how we use it, but we scale to 1000s of VMs.
We use zfs snapshot/clone, expose as an iscsi lun and then use the vbox
built-in iscsi initiator to remotely connect to the LUN on the SAN.
VBox + ZFS + Illumos rocks!!
