I don't think adding annotations as snapshots is the right approach. I think proper support should be added in the header. I wouldn't be too concerned with breaking compatibility in qcow2. That's why it's qcow2 and not just an updated version of qcow, qcow2 is still, AFAIK, open for breakage

[kvm-devel] Storing command line options in qcow2 images

2007-07-29 Thread Jorge Lucángeli Obes
Hi Avi, hi all, I've started some (very minor) groundwork for this task. My idea was to add an extra "annotation" field in qcow2 snapshots. In this way, a snapshot can hold abitrary information; for example, command line arguments. Before going any further, I wanted to validate the general idea w
