Deep Dive: OpenStack Nova Snapshot Image Creation with XenAPI/XenServer and Glance
Based on currently available code (nova: a77c0c50166aac04f0707af25946557fbd43ad44 2012-11-02/python-glanceclient: 16aafa728e4b8309b16bcc120b10bc20372883f4 2012-11-07/glance: 9dae32d60fc285d03fdb5586e3368d229485fdb4) This is a deep dive into what happens (and where in the code) during image creation with a Nova/Glance configuration that is backed by XenServer/XenAPI. Hopefully the methods used in Glance/Nova’s code will not change over time, and this guide will remain good starting point. Disclaimer: I am _not_ a developer, and these are really just best guesses. Corrections are welcome....
