RE: [Xen-users] How do I get a version of Dom0 later than 2.6.18

["Dustin Henning" <Dustin.Henning@xxxxxxxxxxx>]

Dushmant,
        The Fedora-Xen group might be a better place for your question in 
regards to what other Fedora users are doing with F9.  I do not use F9, but 
still F8.  I wonder if you couldn't grab the Dom0 Xen Kernel source from F8 and 
compile it on F9.  Perhaps this would get you a new enough kernel in F9.  What 
I don't know is how compatible it will be with everything else (I guess as 
compatible as can be since it's compiled manually?) or whether or not the Xen 
hypervisor is included in F9 when installing Xen (if not, I guess you would 
have to pick a version and compile it as well).  Anyway, depending on how much 
time and experience you have, it might be worth experimenting with.
        Dustin

With Fedora 9, there is only DomU support in the kernels.

If you need Dom0 Support, you have to use Fedora 8 for Dom0.

This is because Fedora is trying to get the xen patches integrated in the 
mainline kernel. They have managed to do this for DomU, but there seem to be 
some conflicts between the Dom0 patches and more recent versions of the 
kernel.

You can read more about it here:
