Re: [Xen-users] Recent Dom0 kernel

Hi James,

There are many reasons, hardware support and security mostly. The  
system my Xen server is supposed to run on, is about 6 months old  
(the hardware itself was released spring 2008) and contains it  
components that simply aren't supported in a kernel that is more than  
two years old. Support isn't much of a problem either, since I've  
never had a problem with a running system that I couldn't fix (even  
if it ment coding a little) and I have a bit of experience on  
packaging too. The problem is, it's not enough to forward-port the  
existing stuff, so I need a proper patchset to start.
I'm currently still trying a few different things in hope of getting  
the bugs in the Novells kernel 2.6.27 out of the way, but not much  
luck so far. So if you, or anyone else has some hints for me, that  
would be really great.
Thanks,


Paul.
