<div dir="ltr">Update on the Hypervisor Tuning Guide!<div><br></div><div>The plan mentioned earlier is still in effect and is in the midst of Step 2. All etherpad notes have been migrated to the OpenStack wiki and I've recently finished cleaning them up. You can see the current work here[1]. </div><div><br></div><div>For those who may be wondering "why yet another guide?", I guarantee that 9 out of 10 people who read the guide in its current state will learn something new. Imagine how much you could learn if it was complete? </div><div><br></div><div>If you're interested in contributing, please see the How To Contribute section[2]. In short: just add what you know to the wiki.<br></div><div><br></div><div>Here's a list of items that would be great to have:</div><div><br></div><div><div>* Information about Hypervisors other than libvirt/KVM.</div><div>* Information about operating systems other than Linux.</div><div>* Real options, settings, and values that you have found to be successful in production.</div><div>* And ongoing: Continue to expand and elaborate on existing areas.<br></div></div><div><br></div><div>As mentioned before, there is no definitive timeline for this guide. There's no plan to have formal meetings or anything like that at the moment, either. Just an occasional poke to add what you know. However, if you'd like to see this guide fall under a more formal schedule and would like to lead that effort, please get in contact with me.</div><div><br></div><div>Thanks,</div><div>Joe</div><div><br></div><div>1: <a href="https://wiki.openstack.org/wiki/Documentation/HypervisorTuningGuide" target="_blank">https://wiki.openstack.org/wiki/Documentation/HypervisorTuningGuide</a><br></div><div>2: <a href="https://wiki.openstack.org/wiki/Documentation/HypervisorTuningGuide#How_to_Contribute" target="_blank">https://wiki.openstack.org/wiki/Documentation/HypervisorTuningGuide#How_to_Contribute</a></div><div><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Oct 27, 2015 at 9:02 PM, Joe Topjian <span dir="ltr"><<a href="mailto:joe@topjian.net" target="_blank">joe@topjian.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><span style="font-size:13px">We had a great Hypervisor Tuning Guide session yesterday!</span><div style="font-size:13px"><br></div><div style="font-size:13px">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.</div><div style="font-size:13px"><br></div><div style="font-size:13px">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.<br></div><div style="font-size:13px"><br></div><div style="font-size:13px">Our current plan is the following:</div><div style="font-size:13px"><br></div><div style="font-size:13px">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.</div><div style="font-size:13px"><br></div><div style="font-size:13px">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.</div><div style="font-size:13px"><br></div><div style="font-size:13px">3. Once a decent rough draft has been created, we'll look into creating a formal OpenStack document. </div><div style="font-size:13px"><br></div><div style="font-size:13px">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.</div><div style="font-size:13px"><br></div><div style="font-size:13px">Thanks,</div><div style="font-size:13px">Joe</div><div style="font-size:13px"><br></div><div style="font-size:13px">1: <a href="https://etherpad.openstack.org/p/TYO-ops-hypervisor-tuning-guide" target="_blank">https://etherpad.openstack.org/p/TYO-ops-hypervisor-tuning-guide</a></div></div>
