CentOS virt - Nov 2008 - Running Fedora 10 (and rawhide) Xen guests/domUs on CentOS 5 dom0

Hi list!

Now when Fedora 10 is out, I thought of writing here what's needed to
run Fedora 10 Xen domUs on CentOS 5 dom0. 

Fedora 10 does not have separate kernel-xen, but instead Xen domU
support is included in the normal kernel-PAE.i686 and kernel.x86_64 
(based on the pv_ops Xen support included in the mainline/vanilla Linux
kernels).

RHEL 5.3 beta (and final obviously too) includes needed fixes to run Fedora
10 domUs. If you can't wait for CentOS 5.3 upgrade for your dom0, here is
the list of
modifications you need to make for CentOS 5.2 dom0:

In CentOS 5.2 dom0 you should be able to run Fedora 10 domUs/guests if you
first upgrade two packages: 

- libxc (needed for supporting bzImage kernels in F10)
https://bugzilla.redhat.com/show_bug.cgi?id=457199
- python-virtinst (needed for F10 treeinfo parsing)
https://bugzilla.redhat.com/show_bug.cgi?id=460585

Someone with access to RHEL 5.3 beta sources might want to put those
packages available somewhere online.. or even better; compile binary RPMs too :)

Packages:
	python-virtinst-0.300.2-11.el5
	xen-3.0.3-73.el5

I might take a look at it myself later when I have more extra time.. :)

If you put the sources somewhere, I can churn them around.

Just wanted to mention that I built OpenVZ OS Templates for Fedora 10
i386/x86_64 default/minimal and posted them on the OpenVZ site in the contrib
directory to coincide with the Fedora 10 release.  They can be found here:

http://download.openvz.org/template/precreated/contrib/

fedora-10-i386-default.tar.gz               23-Nov-2008 20:20  171M  
fedora-10-i386-minimal.tar.gz               23-Nov-2008 23:30   83M  
fedora-10-x86_64-default.tar.gz             23-Nov-2008 22:50  202M  
fedora-10-x86_64-minimal.tar.gz             23-Nov-2008 23:32   84M 

No special instructions needed... just create a container as usual.

TYL,

It seems Redhat guys have the packages available here:

http://crobinso.fedorapeople.org/rhel5/install_f10/

With those packages installed to RHEL 5.2 (or CentOS 5.2) you can
install/use Fedora 10 guests/domUs.
