[Xen-devel] Xen 4.3 development update

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

= Timeline =

We are planning on a 9-month release cycle.  Based on that, below are
our estimated dates:
* Feature Freeze: 1 March, 2013
* First RC: 15 April 2013
* Release: 1 June 2013

The RCs and release will of course depend on stability and bugs, and
will therefore be fairly unpredictable.  The feature freeze may be
slipped for especially important features which are near completion.

= Feature tracking =

Below is a list of features we're tracking for this release.  Please
respond to this mail with any updates to the status.  If the status
is "?", as most of them are, please respond with the status!  Example
statuses include "not started", "in progress", "initial implementation
submitted for review", "patches submitted".

There are a number of items whose owners are marked as "?".  If you
are working on this, or know who is working on it, please respond and
let me know.  Alternately, if you would *like* to work on it, please
let me know as well.

And if there is something you're working on you'd like tracked, please
respond, and I will add it to the list.


* PVH mode, domU (w/ Linux)
  owner: mukesh@oracle
  status: ?

* PVH mode, dom0 (w/ Linux)
  owner: mukesh@oracle
  status: ?

* Event channel scalability
  owner: attilio@citrix
  status: ?
  Increase limit on event channels (currently 1024 for 32-bit guests,
  4096 for 64-bit guests)

* ARM server port
  owner: ijc@citrix
  status: Core hypervisor patches accepted; Linux paches pending

* NUMA scheduler affinity
  critical
  owner: dario@citrix
  status: ?

* NUMA Memory migration
  owner: dario@citrix
  status: ?

* blktap3
  owner: thanos@citrix
  status: ?

* Default to QEMU upstream
 - qemu-based stubdom (Linux or BSD libc)
   owner: anthony@citrix
   status: ?
   qemu-upstream needs a more fully-featured libc than exists in
   minios.  Either work on a minimalist linux-based stubdom with
   glibc, or port one of the BSD libcs to minios.

 - pci pass-thru
   owner: anthony@citrix
   status: ?

* Persistent grants
  owner: @citrix
  status: ?

* Multi-page blk rings
 - blkback in kernel (konrad@oracle, ?@intel)
 - qemu blkback
  status: ?

* Multi-page net protocol
  owner: ?
  status: ?
  expand the network ring protocol to allow multiple pages for
  increased throughput

* Scalability: 16TiB of RAM
  owner: jan@suse
  status: ?

* libvirt integration
  owner: ?
  status: ?
  To begin with, we need someone to go and make some lists:
  - Features available in libvirt/KVM not available in libvirt/Xen
  - Features available in xl/Xen but not available in libvirt/Xen

* xl vm-{export,import}
  owner: ?
  status: ?
  Allow xl to import and export VMs to other formats; particularly
  ovf, perhaps the XenServer format, or more.


* xl USB pass-through for PV guests
  owner: ?
  status: ?
  - Port the xend PV pass-through functionality to xl.
  - Make sure qemu-based USB with qemu-upstream works
  - Upstream the Linux frontend/backend drivers

* openvswitch toostack integration
  owner: roger@citrix
  status: Sample script posted by Bastian ("[RFC] openvswitch support script")

* Rationalized backend scripts (incl. driver domains)
  owner: roger@citrix
  status: ?

* Linux console improvements
  owner: jan@suse
  -EHCI debug port (done, to be submitted)
  -xHCI debug port
  -Firewire

* CPUID-based idle (don't rely on ACPI info f/ dom0)
  owner: jan@suse
  status: done, to be submitted

* Remove hardcoded mobprobe's in xencommons
  owner: ?
  status: ?

* Make storage migration possible
  owner: ?
  status: ?
  There needs to be a way, either via command-line or via some hooks,
  that someone can build a "storage migration" feature on top of libxl
  or xl.

* Full-VM snapshotting
  owner: ?
  status: ?
  Have a way of coordinating the taking and restoring of VM memory and
  disk snapshots.  This would involve some investigation into the best
  way to accomplish this.

* VM Cloning
  owner: ?
  status: May need review
  Again, a way of coordinating the memory and disk aspects.  Research
  into the best way to do this would probably go along with the
  snapshotting feature.

* Memory: Replace PoD with paging mechanism
  owner: george@citrix
  status: May need review

* PV audio (audio for stubdom qemu)
  owner: stefano.panella@citrix
  status: ?

* Managed domains?
