In progress (just need to double check whether finished)

Improve networking documentation

Expand Host Configuration/Networking docs to cover non-bridge network configurations supported by xend (e.g. routed, nat'd). Possibly split into a page per config.

A Xen Performance Tuning Guide

Open work items

Xen Wikipedia page

Review and update http://en.wikipedia.org/wiki/Xen - in particular the "Host: Unix-like systems" is out-of-date. The Guest section is too.

Getting started with Xen using xen-tools

Given that we are getting a lot more total novices to the community I was wondering whether it makes sense to add something like: getting started with xen-tools. See http://www.virtuatopia.com/index.php/Building_a_Xen_Guest_Domain_using_Xen-Tools and http://xen-tools.org/software/xen-tools/ and http://www.gossamer-threads.com/lists/xen/users/246910 this.

XCP Overview

Similar to Xen Overview

A Xen Security Guide

The different options in Xen for Security, trade-offs, how to set them up, how to test Xen for security and how to optimize for different scenarios

Xen 4.2: VCPU pinning

Some more documentation outside the context of NUMA, see Xen_Numa_Scheduling_and_Placement

Review and Update: xenpm usage recommendations

There is Xen power management and Xenpm command which may all be outdated. These should probably be reviewed and updated.

HOWTO : using xm trigger to poweroff or firing off NMIs

Howto on using xm trigger to poweroff or firing off NMIs.

HOWTO: Setting boot order for domUs (PV and HVM)

Howto set up boot order for domUs (all virt modes)

HOWTO: Chain pypxeboot and pygrub

How to chain pypxeboot and pygrub

  • Lars.kurth 10:35, 27 March 2012 (UTC): Is pypxeboot popular at all?
  • Fheigl I added that. It is somewhat common, OVM 2 and OVM 3 rely on it for PXE installs. I'm not sure if xenpvnetboot is the same, or works. The use case is "you want to use the same installation server for Xen VMs and phys. servers. You want to be able to reinstall them based on PXE reply.
  • Fheigl There is documentation for pypxeboot, but there is no (afaik) documentation for how pygrub is used as a fallback loader. We wasted many days just to get some hack that can't even load a newer kernel. Which sucks, in the end you spend more time/money making PV PXE boot work than you save by using virtualized servers.
  • Fheigl Q3: How could it be popular given the state of documentation. <= Key issue to the left of this sentence.

Review Categorization

We need to go through some of the categies on the http://wiki.xen.org/wiki/Main_Page and decise whether there are documents in each category that need to be highlighted in a trail, etc.

Loose ends on migration
