We had a great Hypervisor Tuning Guide session yesterday! We agreed on an initial structure to the guide that will include four core sections (CPU, Memory, Network, and Disk) and common subsections to each. The etherpad[1] has this structure defined and during the session, we went through and added some brief notes about what should be included.
Another agreement was that this guide should be detailed. It should have specific actions such as "change the following sysctl setting to nnn" rather than being more broad and generic such as "make sure you aren't swapping". One disadvantage of this is the guide might become out of date sooner than if it was more broad. We felt this was an acceptable tradeoff. Our current plan is the following: 1. We're going to leave the etherpad active for the next two weeks to allow people to continue adding notes at their leisure. I'll send a reminder about this a few days before the deadline. 2. We'll then transfer the etherpad notes to the OpenStack wiki and begin creating a rough draft of the guide. Brief notes will be elaborated on and supporting documentation will be added. Areas that have no information will be highlighted for help. Everyone is encouraged to edit the wiki during this time. 3. Once a decent rough draft has been created, we'll look into creating a formal OpenStack document. We're all very busy, so there are no definitive timelines for completing steps 2 and 3. At a minimum, we'll continue to touch base with this during the Summits and mid-cycles. If there's enough interest, we could try to schedule a large block of time to do a doc sprint during one of these events.
