AMD is actively testing Christoph Egger has helped out a bit ACTION: Carried over, was started in May, but not much activity due to vacations
- Konrad: to approach Coverity about free service and ask about security
 
Lars offered to sync up with Coverity at CLS ... no Coverty rep attended
Ongoing work
Boris: How do we handle incomplete features in Xen?
George: depends on size and risk of feature. We can mark it as experimental. Note that we don't have a separate staging tree, so we tend to not compile incomplete features by default. Example boot options (not enabled by default).
Konrad: asked whether we had a general rule/guidance about this
George: We tend to #ifdef incomplete code out. For example PVH code can be checked in with #ifdef's to reduce the need for catch-ups. There is also the option to host personal public branches on a xenbits git tree
Coordination on current & future work
Xen 4.4 Planning
Goals
- Shorter release cycle (from 9 to 6 months) - see George's 1st 4.4 Development Update on xen-devel. Advantages: shorter RCs, less impact if changes are missed
 
Proposal:
- Plan for Jan 21st release of 4.4
 - Feature freeze mid-October
 
 Action All: provide feedback, raise hands if this is an issue
George has an internal backlog. Big items:
- Event Channel Scalability
 - PVH Mode
 - Credit2 scheduler as default
 - I/O improvements - see Hackathon minutes at http://wiki.xenproject.org/wiki/Hackathon#May_2013_.5BHackathon_Minutes.5D
 - Elena's virtual NUMA topology work
 - Nested Virt: would like to move to production in 4.4
