Hi there guys As a test, I started using the same kernel and initramfs like in Dom0 which i know it works, but when starting up DomU I've get. switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init Not tainted 2.6.31.13 #14 I've got the same error while setting up Dom0 and was a problem with the scsi modules which I included in the kernel and not in the initramfs, my bad !! My config file looks this. #---------------------------------------------------------------------------- # Kernel image file. kernel = "/boot/vmlinuz-2.6.31.13" # Optional ramdisk. ramdisk = "/boot/initrd-2.6.31.13.img" disk = [ 'phy:VG-NW/root,sda1,w','phy:VG-NW/swap,sda2,w' ] Also copied the /lib/modules/kernel_version to the *guest* partition. What am I missing?
