Yes, at first I tried with kernel-xen-devel, but it didnt woked, and I 
didnt find any kernel.X.xen.fc6.src.rpm :(
But (if i well understand) here 
(http://hany.sk/~hany/RPM/fc-updates-6-i386/kernel-xen-devel-2.6.20-1.2952.fc6.i686.html) 
i see that kernel-2.6.20-1.2952.fc6.src.rpm 
<http://hany.sk/mirror/fedora/core/updates/6/SRPMS/kernel-2.6.20-1.2952.fc6.src.rpm> 
provide kernel-xen-devel-i686 
<http://hany.sk/%7Ehany/RPM/kernel-xen-devel-i686.html> so i decided to 
try with it...
When i tried with kernel-xen-devel i was unable to do the "make"...
