Hi, many thanks to Michael and Daniel, for your pertinent comments. Next question is nothing related to cobbler or koan, but perhaps you can help me about it. when i run the koan command (koan --virt --server=136.145.116.78 --profile="..."), at the end i got the next message: Creating root device. Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! It appears the installation has crashed The problem at this time, is that kernel image try to mount the root partition to device that is not available. I know the command "rdev" allows me change the root partition that kernel image expected. What's the suitable partition in order to follow with the installation? thanks a lot, regards.
