Hi. I am trying to build a differencing disk system that has a parent disk which is read-only and then programmatically create a differencing disk from the parent. Similar to how Virtual PC and VMware work.
I am looking at two different options: 1) A snapshot is really is differencing disk. There is an option in the GUI to "Show differencing disks" so it seems there may be a path to leverage this functionality to create a snapshot and then to use this as a basis as a template. Maybe this could be used in combination with "2)". 2) Use empty dynamic VDI files and then try to link them to the parent. How does vbox manage the linking? Is there some information in the file header telling it where the parent is located? I opened one up, but nothing obvious jumped out at me. Any suggestions on these options? Ideally, we would be able to support nested differencing disks, where you could have two or three disks linked to each to each other. Anyone know if this feature is on the roadmap?
