Ganeti! could not add os for instance

[luannunes]

Hi everyone,

I'm following this tutorial: http://www.howtoforge.com/xen-cluste...ebian-lenny-p3

i set everything as the tutorial showed... hosts, interfaces, drbd.. ALL.

An error occurred after using this command:

gnt-instance add -t drbd -n slave.com:master.com -o debootstrap -s 3g --swap-size 128 -m 256 --kernel /boot/vmlinuz-`uname -r` --ip 192.168.0.106 webserver.com

and was supposed to be so:
