This post is a deep dive into what happens in Nova (and where in the code) when a console URL is retrieved via the nova API for a Nova configuration backed by XVP and XenServer/XenAPI. Hopefully the methods used in Nova’s code will not change over time, and this guide will remain good starting point. Example nova client call: [code]nova get-vnc-console [uuid] xvpvnc[/code] And the call returns: +--------+-------------------------------------------------------------------------------------------------------+ | Type | Url | +--------+-------------------------------------------------------------------------------------------------------+ | xvpvnc | https://URL:PORT/console?...

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....

Based on currently available code ( a77c0c50166aac04f0707af25946557fbd43ad44 2012-11-02) This is a deep dive into what happens (and where in the code) during a rescue/unrescue scenario with a Nova configuration that is backed by XenServer/XenAPI. Hopefully the methods used in Nova’s code will not change over time, and this guide will remain good starting point. Rescue nova-api receives a rescue request. A new admin password is generated via utils.generate_password meeting FLAGS.password_length length requirement....

Based on the currently available code ( commit 114109dbf4094ae6b6333d41c84bebf6f85c4e48 – 2012-09-13) This is a deep dive into what happens (and where in the code) during a resize down (e.g., flavor 4 to flavor 2) with a Nova configuration that is backed by XenServer/XenAPI. Hopefully the methods used in Nova’s code will not change over time, and this guide will remain good starting point. Steps 1-6a are identical to my previous entry " Deep dive: OpenStack Nova Resize Up with XenAPI/Xenserver"....

Nova is the Compute engine of the OpenStack project. Based on the currently available code ( commit 114109dbf4094ae6b6333d41c84bebf6f85c4e48 - 2012-09-13) This is a deep dive into what happens (and where in the code) during a resize up (e.g., flavor 2 to flavor 4) with a Nova configuration that is backed by XenServer/XenAPI.
