Re: [Xen-devel] Xen 4.5 Development Update (RC4) - Documentation Updates
Hi all,
in preparation for the release we need to update some wiki pages, as well as
in-tree docs
First of all, any new features for which any of you have written new wiki pages
should be marked with [[Category:Xen 4.5]]. Either do this, or reply with URLs
to pages and I will do so
Otherwise, I created boilerplate pages for various pages and tracked the status
on http://wiki.xenproject.org/wiki/Category:Xen_4.5
@Russell: you may want to update the XM to XL pages or create a new one and add
your video
== The following pages need to be reviewed and updated ==
* {{NotDone}} [[Linux PVH]]:
** Add PVH Dom0 information
** Review/correct the '''Things that are broken''' section
** Review/correct the '''Items that have not been tested extensively or at
all'''
* {{NotDone}} [[Xen ARM with Virtualization Extensions]]
** supported platforms need to be updated and
** all platforms that are supported in 4.5 tagged appropriately with
[[Category:Xen 4.5]]
== Lars will fix ==
* {{NotDone}} [[Xen Project 4.5 Acknowledgements]]
** Lars will do this.
* {{NotDone}} [[Xen Project 4.5 Feature List]]
** Lars will copy from the blog announcement when ready (Sarah is currently
making some final changes)
== For Konrad and others ==
* {{NotDone}} [[Xen Project Release Features]] - main 4.5 features need to be
added.
Please reply to the thread and I will add that page.
** The key changes normally are changes to scalability/memory/etc. limits -
maybe Jan(x86) and Ian(ARM) can look let me know of changes
** Also new platforms, changes to experimental features, etc.
** Probably the new scheduler should be added - is there a wiki page?
** Any other major new features that are worth highlighting? I can go through
the press release and the release note
* {{NotDone}} [[Xen Project 4.5 Release Notes]] - needs to be created
** http://wiki.xenproject.org/wiki/Xen_Project_4.4_Release_Notes were pretty
lightweight
** I think we should keep it that way. We should probably mainly focus on known
issues
@Konrad: what's your view?
== Missing pages ==
* {{NotDone}} [[Xen Project 4.5 Man Pages]]
** need to clone [[Xen Project 4.4 Man Pages]] and point to the correct branch
when the 4.5 branch has been created
** if there are new documented features in in-tree docs then add them
** if there are irrelevant features such as XM, remove links to docs (probably
the docs should be removed from the git tree also)
Cheers
Lars

Xen 4.5-rc4 was out on Monday (Dec 15th). This is the last RC and then
we have the General Release on Jan 7th!
Details for the test-day are at
http://wiki.xen.org/wiki/Xen_4.5_RC4_test_instructions
In terms of bugs, we have:
#11 qxl hypervisor support
#13 Re: [Xen-devel] man page example: xm block-attach
#18 xl improve support for migration over non-sshlike tunnels
#19 xl migrate transport improvements
#22 xl does not support specifying virtual function for passthrough device
#23 Remove arbitrary LIBXL_MAXMEM_CONSTANT from libxl, see what breaks
#24 xl missing support for encrypted VNC
#27 Re: [Xen-devel] xend vs xl with pci=['bdf'] wherein the 'bdf' are not
owned by pciback or pcistub will still launch.
#28 support PCI hole resize in qemu-xen
[ 'mmio_hole' fix it, but the ultimate way is to fix it in QEMU]
#30 libxl should implement non-suspend-cancel based resume path
#36 credit2 only uses one runqueue instead of one runq per socket
#38 Implement VT-d large pages so we can avoid sharing between EPT
#40 linux pvops: fpu corruption due to incorrect assumptions
#42 linux, S3 resume of PVHVM fails - missing call to xen_arch_post_suspend?
#43 30s delay loading xenfb driver on some systems
#44 Security policy ambiguities - XSA-108 process post-mortem
#45 arm: domain 0 disables clocks which are in fact being used
#46 qemu-upstream: limitation on 4 emulated NICs prevents guest from starting
unless PV override is used.
= Timeline =
We wer planning on a 9-month release cycle - but it is more like an
10 month. Based on that, below are the estimated dates:
* Feature Freeze: 24th September 2014
* First RC: 24th October [Friday!]
* RC2: Nov 11th
* RC2 Test-day: Nov 13th
* RC3: Dec 3rd.
* RC3 Test-day: Dec 4th
* RC4: Dec 15th
WE ARE HERE ===
* RC4 Test-day: Dec 17th
Release Date: Jan 7th.
The RCs and release will of course depend on stability and bugs, and
will therefore be fairly unpredictable.
Bug-fixes, if Acked-by by maintainer, can go anytime before the First
RC. Later on we will need to figure out the risk of regression/reward
to eliminate the possiblity of a bug introducing another bug.
= Prognosis =
The states are: none - fair - ok - good - done
none - nothing yet
fair - still working on it, patches are prototypes or RFC
ok - patches posted, acting on review
good - some last minute pieces
done - all done, might have bugs
= Bug Fixes =

Just make sure, when you do that, that you properly adapt the information and make them match what actually have been upstreamed (so command option names, limits of the implementation, etc.) Also, you should put in the wiki page a WARN about the fact that the scheduler has been included as an experimental and in-development feature.

Lars, @Russell: you may want to update the XM to XL pages or create a new one and add your video I've updated the existing Wiki pages. I've also created an unpublished entry in the Video section of the XenProject.org website. Should we publish that now, or wait until release?
