Fedora xen - Mar 2008 - Plans for paravirt_ops kernel-xen

Hi,
        Fedora''s Xen hackers have been working hard towards switching
our kernel-xen package from a forward-ported Xensource kernel tree to a
state-of-the-art upstream, paravirt_ops based, kernel in Fedora 9 as
described here:

  http://fedoraproject.org/wiki/Features/XenPvops
  http://www.redhat.com/archives/fedora-xen/2007-November/msg00106.html

        Some great progress has been made, and tomorrow''s rawhide will
have a kernel-xen update with:

  + A very recent 2.6.25-rc4 base

  + Xen paravirt_ops DomU from upstream

  + x86_64 Xen paravirt_ops DomU support

  + Paravirt framebuffer

        However, although the Dom0 paravirt_ops work is well advanced at
this point, we still don''t have backend drivers or x86_64 Dom0 working.

        With the feature freeze looming next week, we have make the
difficult decision to focus the Fedora 9 efforts on DomU and postpone
the inclusion of paravirt_ops Dom0 support.

        The alternative course of action was to keep shipping the
2.6.21.7 based kernel-xen in Fedora 9, but we have ruled this out as a
supportable option. This kernel is almost a year old now and we cannot
expect Fedora hackers to keep the distribution working on such an old
kernel. Examples of the kind of issues we see cropping up are:

  1) Broken installs due to old squashfs:

       https://bugzilla.redhat.com/431109

  2) Broken SELinux due to old SELinux:

       https://bugzilla.redhat.com/436173

  3) Broken networking due to old netlink:

       https://bugzilla.redhat.com/431179

        We feel that making significant investment across the
distribution to keep this old kernel working for the sake of Dom0
support would be wasting effort on a dead codebase.

        Work will continue apace on the Dom0 paravirt_ops effort for
Fedora 10 and we hope to introduce the first build to rawhide soon after
Fedora 9 been branched. This first build should include backend drivers
and x86_64 support. If all goes well with the Dom0 support in Fedora 10
rawhide, we may well pull it into Fedora 9 as a post-GA update.

        So, in summary:

  1) Try out the F9 rawhide/beta paravirt_ops kernel-xen in your DomUs

  2) Keep your Dom0 on Fedora 8 for now

  3) If you want to help out with Dom0 paravirt_ops testing, then be
     ready to jump onto Fedora 10 rawhide

Thanks,
Mark.

I forgot to mention a minor detail :-)

kernel-xen-2.6.25-0.0.rc4.fc9.x86_64 doesn''t actually boot, but
hopefully Eduardo will have that fixed up in the next short while ...

It boots fine with the config Eduardo was using in testing, but blows up
with the stock Fedora config.

The i686 kernel seems to be in good shape, so please do give that a
hammering.

Cheers,
Mark.

Do you expect that the DomUs from the final Fedora 9 release will work 
smoothly with the Dom0 from RHEL/CentOS 5.1?

Yes, F9 DomU will fully support the Xen 3.x guest ABI, so should be compatible
with any host running Xen 3.x releases including RHEL-5 and Fedora >= 5

First I''d like to thank you guys for doing this work. I think
it''s very
important to get good Xen support working and integrated into upstream kernel.

Was there some specific problem/bug about dom0 support (backend drivers and
x86-64), or just not enough time? 

Thanks!

Simply lack of time - stability of DomU is of most importance because we
can''t change the $INSTALL_TREE/images/xen/{vmlinux,initrd.img}  once F9
is released. So we need to prioritize DomU support.  Pushing out a new
kernel to add Dom0 is trivial post-GA since it doesn''t impact installer
images.

Then what would be the Dom0 kernel in Fedora 9?

Nothing.

There will *not* be any Dom0  kernel in Fedora 9 GA release. People who
need Dom0 should stay on Fedora 8.  We will work on Dom0 for Fedora 10,
and if it is stable enough release it as an Fedora 9 update after GA.

You can use xenner to run your Xen DomU, if your machine has hardware 
virtualization extensions, without a Dom0.

Any sufficiently difficult bug is indistinguishable from a feature.

In theory yes, but we''re still working on getting Xenner integrated
with
the management tools & aren''t confident of getting that completed
for
F9 GA either, so I wasn''t going to mention Xenner yet. It also has a
bug
currently preventing it from receiving network traffic

Hey,
	So, just a status update on beta critical bugs with this kernel-xen:

 1) x86_64 kernel won''t boot

      https://bugzilla.redhat.com/436485

    Eduardo is investigating

 2) Anaconda will only do a text mode install at the moment

      https://bugzilla.redhat.com/434763

    Jeremy seems to be on top of this

 3) Intermittent boot failure due to disk probing race condition:

      https://bugzilla.redhat.com/436493

    We''ve a good idea what the fix is, someone just need to backport it
    and pull it in.

 3) Oops during yum update

      https://bugzilla.redhat.com/436453


	We have a tracker bug here:

  https://bugzilla.redhat.com/showdependencytree.cgi?id=PvOpsTracker

	Please log any further bugs and add them to the tracker.

Cheers,
Mark.

Is a public git tree of this kernel available somewhere ?

Thanks,

	Unfortunately not. I must move my tree moved to a public server.

	However, the biggest chunk is definitely Eduardo''s x86_64 work which
is
here:

  http://git.et.redhat.com/?p=xen-pvops-64.git

	You can also see the patches that we''re including here:

  http://cvs.fedora.redhat.com/viewcvs/rpms/kernel-xen-2.6/devel/

	(All the linux-2.6-xen-00....patch patches)

	The quick summary is:

  - Eduardo''s x86_64 patches (only applied on x86_64)
  - Marcus''s latest pvfb patches
  - Frontend module auto-loading and compat aliases
  - Mark hvc0 as a preferred console
  - xenctrl module
  - vmlinuz target
  - Execshield revert

Cheers,
Mark.

	Okay, Dan sorted me out:

  http://git.et.redhat.com/?p=linux-2.6-fedora-pvops.git;a=summary

	Best thing to do is look at the tags where I rebase the patchset, merge
commits etc.:

 
http://git.et.redhat.com/?p=linux-2.6-fedora-pvops.git;a=shortlog;h=3a3aec06918f36a7e8d9deff1063a709a193b89f

	There are also "kernel-xen" tags which correspond to the source being
built in the RPMs; that includes all the patches from the bare-metal
kernel RPM.

Cheers,
Mark.

Yep. Thanks for the update!

When is fedora 10 rawhide expected to open? Meaning when we can start
testing kernel-xen with dom0 support :)

-- Pasi

I belive at the end of this year.

Hmm.. I think it''s sooner..

Mark wrote like this:

"Work will continue on the Dom0 paravirt_ops effort for Fedora 10 and we

branched."

I was just wondering when that actually is.. is it when F9 is released (29
April 2008) or sooner, perhaps after F9 beta freeze?

Actually looking at this: http://fedoraproject.org/wiki/Releases/9/Schedule

8 April 2008 "Branch all packages for Fedora 9"

So I guess that''s the answer.. :)

Hi there!

It''s May now, and today is the day for Fedora 9 to be released. So any
news
on F10 dom0 support? Is this already implemented in the meantime? I
don''t
want to nag anyone, don''t get me wrong, please... I am using Kubuntu
8.04
ATM, and am facing loads of troubles with Xen. Now I wanted to give F9 a
try, but it turns out that there''s no dom0 support... So I would like
to
give F10/rawhide a try, and maybe get things working again... :)

Thanks,
Daniel

Our advice for now would be to either use Fedora 8 for Xen Dom0 or try
using KVM in Fedora 9.

Mark.

Yes, I forgot that third option - you can use xenner with F9 to run Xen
paravirt guests.

Xenner is still very new & raw in F9 - I''m in process of finishing
off
libvirt integration. Come F10 xenner will be 100% supported in Fedora
and we''ll  likely push out updates to F9 at some point too. If you have
Xenner installed and are using virt-manager with the ''QEMU''
driver it
will automatically detect Xenner and give you the option of choosing
paravirt in the new VM wizard.
