Fedora xen - Jun 2008 - No Dom0 support in Fedora 9 and Fedora 8 EOL

I''m putting together a virtualized server. I was planning to use 
Fedora 9, until I found out that Fedora 9 won''t run as a Dom0, so 
I ended up using Fedora 8 instead.

I also learned that the standard EOL policy is to discontinue 
support for release N one month after the release of release N+2.

Since Dom0 support isn''t expected until Fedora 10, it sounds like 
this means that I will have to upgrade my system in the first 
month immediately following the release of Fedora 10, or lose 
support. Neither option seems particularly reasonable to me.

Since upgrading from Fedora 8 to Fedora 9 isn''t an option for 
anyone using Xen, I am wondering if there is any plan to extend 
Fedora 8''s support period beyond the usual one month?

Frankly I don''t know but I don''t think that this is very
likely to happen. If
upgrading is an issue for you, you should look at RHEL (or one of the
''gratis''
clones like CentOS).

Oh, and besides that I''m note sure if running Xen/Dom0 on Fedora 8 is 
advisable from a security pov: I think the xen kernel (2.6.21) lacks quite a 
few security patches that the normal Fedora kernel already got...

Damn - I have just run into the buffers because of that.
I have just reinstalled my test box with Fedora 9 ... wanted to
run several guests under it. Shame it was not flagged up bigger somewhere.

I don''t have an issue with upgrading; I chose Fedora because I 
wanted a distro that was at the leading edge.

But that doesn''t mean that I want to upgrade to the latest Fedora 
release on the same day it''s released. I will upgrade during the 
one-month grace period if I have to, but I would have been more 
comfortable with a little more wiggle room.

OK, so what would you recommend then?

What are your requirements ?
Perhaps:

* Modern Dom0
* Ability to run LVM
* ISO image to install from

For me:
* x86_64
* something that comes with X windows

I''m currently on an F8 Dom0 at the moment, but I''ll need to
upgrade Xen
fairly soon. At the moment, it seems to me that one of the Solaris 
distros is the way to go, particularly since they have built-in Windows 
PV drivers. There also seems to be a lot of development activity.

You''ll need to ask Dan Berrange to be certain, but I''m pretty
sure the plan is to have a dom0 kernel ready some time during the
lifetime of F9.

The reason we don''t have an F9 dom0 kernel right now is because
there *isn''t one*.  Ask XenSource to provide something more recent
than > 2 year old Linux 2.6.18 support!  Red Hat are committing
two full time developers right now to fix this situation, but it
is NOT our fault.

You might also want to try out KVM.

Thanks for the clarification. I''ll keep on the lookout for updates 
in F9.

Fedora 9 is basically DomU only and we''re still working on getting the
x86_64 patches accepted in upstream LKML trees. Best guess is that this
will be 2.6.27 . In parallel we''re still working on Dom0 support with
pvops

It''s been pointed out to me that Jeremy Fitzhardinge (at XenSource)
is driving the pv_ops work which will bring a modern dom0 into
Fedora 9 or 10.

I don''t want to forget or diminish Jeremy''s crucial efforts.
