[Planetlab-devel] Help for boot a node!

bootmanager logs are in principle uploaded on the myplc side in /var/log/bm
raw log files are stored in raw/ and then symlinks are created in the other subdirs to help navigating in the mess :)
the bm logic is to first start a failsafe sshd instance, that runs in the context of the bootcd
the regular sshd, that runs in the context of the hard-drive, can be triggered only later on, after a successful kexec can be triggered from the installed hdd
the failsafe sshd uses the key from /etc/planetlab/debug_ssh_key*, while the regular sshd accepts connections using any public key attached to an administrator, as well as the one from /etc/planetlab/root_ssh_key*
You should thus try these keys according to the stage where the installation failed
this being said, if the node could not use a network interface at all, then of course you're out of luck with any of this; but it might also be that the bootCD could setup the interface and the hard-drive install could not..
in any case, for any further assistance, please provide your precise release info, as found in /etc/myplc-release
hope this helps -- thierry
