Hi I am running opensuse 11 on a Sun x4150 32GB RAM 2 quad x86_64 xeons. It has a SAS PCI-Express LSI 3081E Host Bus Adapter running in a RAID 5 config. The problem I have is that when I try to run a the xen kernel the RAID device is not found . I get messages on the console of "can't find /dev/disk/by-id/<name of raid-device>partno. Do you want to fall back to ......" There are no issues running a non-xen kernel. I have checked the initrd and the module list is identical to those loaded by the non-xen kernel. I have changed the root= grub option to use /dev/sda3 which is the correct root partion reported by df when the system is running. I have remade the xen initrd All of these have made no difference at all. I know that the xen hypervisor sits between the CPU, memory, PCI bus and the dom0 kernel and wonder if there are any kernel options (xen specific or not) that might get me out of my dilemma. Details to follow ( all as reported by the non-xen system) Grub config is ######################################################## # Modified by YaST2.
