Hi, Does anyone know if it is possible to patch an older kernel (eg. 2.6.9) so it can be compiled to run as a Xen kernel (dom0)? Thanks! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Now, my question is: Why would you want that? I can understand why someone would want a DomU to run an older kernel - to be compatible with some SW that is tested and approved for 2.6.9 exactly, and no other kernel - but for Dom0 that should only be a service-OS for the domU''s, it shouldn''t make any big difference what kernel you''re running. And of course, not so long ago, the complaint was that Xen was not supporting the latest kernel - not from you, but that was a common comment on this mailing list... -- Mats> > Thanks! > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You''d just have to look at which patches are the biggest - and I think Xen is quite intrusive, so unless your other patches are also touching a lot of files in the kernel, I would suspect that porting the other patches would be easier... -- Mats> > -- > Sylvain > > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi, Thanks for the reply! Essentially I have a binary driver. There are only a few OS''s which it works under. Unfortunately IBM say that they don''t have much ''swing'' in getting their suppliers to open source the driver and Adaptec seem to have made it impossible to make contact with them unless you have bought from them directly. If I could patch the kernel which comes with the distro so it was "xenified" ( :) ) then perhaps I could continue to use the same driver. In this case, as it is a RAID type of device I''ll have to opt to use software RAID. Thank you again for the reply.

At least, I think that is still a problem in Xenified Linux as it is under HVM - drivers in Xenified Linux are modified to "understand" Xen, and that''s not going to work with binary drivers. However, I may be wrong. Someone with better understanding of this may be able to correct me (or say I''m right). -- Mats> > Petersson, Mats wrote: > > > > > >> -----Original Message----- > >> From: Sylvain Coutant [mailto:sco@adviseo.fr] > >> Sent: 16 May 2006 12:02 > >> To: Petersson, Mats; ''Julius Spencer''; > xen-users@lists.xensource.com > >> Subject: RE: [Xen-users] Basic Xen Question > >> > >>>> Does anyone know if it is possible to patch an older kernel (eg. > >>>> 2.6.9) so it can be compiled to run as a Xen kernel (dom0)? > >>> Now, my question is: Why would you want that? > >> ie, just because one have some other patches to apply against the > >> kernel.

Are you sure the adaptec driver is not in the kernel. I have adaptec to be very good, in terms of opening up their drives. I have not come across one that wasn''t already in the kernel. I have used SCSI and SATA Controllers and RAID variants of each without getting any drivers from adaptec. Greg.

Yeah, unfortunately no. I think it is one of the few that isn''t, from Adaptec (my luck!). It''s module name is: adpahci ; I haven''t found this anywhere except as Suse and RHEL rpms. If you have heard of it though, do let me know. It''s the Adaptec HostRAID (IBM ServeRAID-8e) embedded in the motherboard. From what I''ve read it''s fakeraid, but at least it must deliver some resources which would have been nice... Plus there''s a sweet IBM application which lets you manage and monitor the RAID (if it can find the controller via the OS).

That sounds like my IBM ServeRaid 7. I don''t know much about the 8, do you know what the adaptec equivalent is? I think mine is the 2410SA, and that uses the aacraid module.
