= Review Action Items =
* Lars: logistics of opening up the call
Hard to open the call completly for practical reasons, but could relax the rules and allow people to request an invite and manage that way.
Konrad was in favour of an open call, but the above works for him.
Lars will talk with Ian about practicalities and send round a detailed proposal.
= Current Technical Challenges =
== Recurring need for pings on VMX/SVM/IOMMU patches ==
Jan finds the turn around, especially for the above areas, to be far too slow. Each patch series requires continual pinging to get a response. Will it be possible to improve. Both Intel and AMD are aware.
Ian: Can Jan escalate via email to someone? Sherry: Can be CCd if things are not getting a response.
Jan: is specificaly worried about lack of response from people listed in MAINTAINERS. Jan wants to avoid pushing patches without review, especially in these areas where things can go wrong.
Sherry: Vendors have access to larger test beds.
Jun: Is a resourcing issue. Need a focal point, Jun will figure out who that should be.
 to figure out the focal point. Will Auld is the respective person.
Jan: Doesn't need a response within hours, but should be a couple of days but not weeks or months.
= Coordination of current and future work =
== xend ==
Matt: People are still using xend
Ian: It has been deprecated for two years and two releases.
Matt: Wants to keep it on lifesupport. Wants to add some MAINTAINERS, tagged obsolete.
Ian: What level of support? Concerned about new deployments.
Matt: Not ressurected or supported, but somewhere for patches to go.
Ian: Could we create xend.git?
Matt: Need to think about how much to get rid of? e.g. keep Python bindings.
Ian: Move xend and xm into another tree, but retain bindings in the tree.
Konrad: 
Ian: Breaks the build, consumes test resource.
Konrad: Need to make sure xl is a good replacement
Ian: We've been asking for two release now. How do we make progress.
Konrad: Need to make sure there are no regressions, because some people still depend on it.
Ian: That should be up to the people who are using it.
Matt: Should not remove from osstest.
Konrad: Disable in the build by default, big warning reference to xl.
Ian: Disabling the build is the very minimum.
Ian: How about Disable for 4.4 and delete first thing after 4.4 release.
Jan: Is in favour of that.
Jan: How about make all remaining 4.4 blockers regressions
Matt: We need "xl create -S" to work, otherwise need to rework their toolstack. But sxp supprt does not seem like the best thing for the project.
Revision:
It's "xl create -F". 
Matt: Things like "xl create -F" don't work. But sxp support does not seem like the best thing for the project.
 to reply to the 4.4 planning thread with their BLOCKERS.
Boris: Do we need to post to xen-users?
Ian: It's been in the release notes several times.
Various: No one reads that stuff, or lists etc.
Ian: We've done enough
james: Warnings when running xm
 to write said patch
== PV NUMA ==
Matt: First series sent out by intern, are we expecting any more?
James: Dario has been mentoring, just back from vacation, but thinks more is coming soon.
Konrad: Another RFC will be submitted.
