Re: [Xen-users] how to build xen + dom0 and domU from source?

[Riccardo Veraldi <Riccardo.Veraldi@xxxxxxxxxxxx>]

it won't work.
it will work straight for kernel 2.6.18.
But for any other kernels 2.6.18.X it won't work.
Otherwise you need specific patches to be applied but they are not 
present in hte default
xen 3.1.0 sources.
I can provide you a src rpm with all te patches needed to compile Xen 3.1.2
under the latest RHEL5 kernel 2.6.18-53.1.4
