Hey all, I have need to boot 32bit domu''s on a amd64 system. I was able to deploy a 32bit image but the kernel is still 64bit. I have a feeling in my .cfg file for the domU I need to specify a 32bit kernel. Is this correct? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Unless you use pygrub/pvgrub to load the kernel from domU filesystem. -- Pasi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Where the kernel located depends on domU setup, can be in dom0 (thus specified in domU config file) or within domU filesystem (when using pygrub/pvgrub). -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
These config files were suggested to me by Pasi Kärkkäinen you can check them I am posting here for reference. http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.31.4-pvops_dom0-x86_64 http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.31.5-pvops_dom0-x86_32 I am right now working to get a Debian system working for Dom0 kernel if you get some success let us know here.
