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

 Action George: Kick of 4.4 planning discussion on xen-devel ✓
