[one-users] Attaching big immutable disks to virtual machines

[Ruben S. Montero]

Hi

On a second thought, the low level operations for an image are controlled
by SAVE (will be copied back to the image repo) and CLONE (will be copied
vs linked).

We could deal with this volumes as if they were CDROMs, i.e. READONLY=YES,
CLONE=NO, SAVE=NO. The disk images will be linked and mounted by multiple
VMs at the same time in a ro mode, so no need to have a virtual SAN
underneath .

Would that make sense? I'll fill an issue for this if so...

Cheers

Ruben
