Hello to Everyone, I recently installed OpenSuSE 12.1 and I want to experiment with the xen kernel.I down-loaded the xen kernel from the OpenSuSE repository. When I tried to boot into it, I got the following message: ERROR 13: invalid or unsupported executable format [ Filesystem type is ext2fs, partition type 0x83] ###(Part of Error message) Would someone suggest how to correct for this error? Thank you. I am going to send some information along with this request in case it might be useful: This is some of the out-put of fdisk -l: Disk /dev/sda: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders, total 156301488 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000028ef Device Boot Start End Blocks Id System /dev/sda1 63 4209029 2104483+ 82 Linux swap / Solaris /dev/sda2 4209030 46154744 20972857+ 83 Linux /dev/sda3 46154745 114350668 34097962 83 Linux /dev/sda4 * 114352128 156301311 20974592 f W95 Ext'd (LBA) /dev/sda5 114354176 131123199 8384512 83 Linux /dev/sda6 131125248 156280831 12577792 83 Linux This is some of the out-put of etc/fstab: /dev/disk/by-id/ata-ST380021A_3HV32KHZ-part1 swap swap defaults 0 0 /dev/disk/by-id/ata-ST380021A_3HV32KHZ-part5 / ext4 acl,user_xattr 1 1 /dev/disk/by-id/ata-ST380021A_3HV32KHZ-part6 /home ext4 acl,user_xattr 1 2 proc /proc proc defaults 0 0 sysfs /sys sysfs noauto 0 0 debugfs /sys/kernel/debug debugfs noauto 0 0 devpts /dev/pts devpts mode=0620,gid=5 0 0 ~ ~ From these two items, the fifth partition is root and has a ext4 filesystem.
