Yes I have try to run the guestmount command independently and it was OK.
Yes I have removed the "guestmount" command line from the system and after that, Nova was able to activate instances.
I can't reproduce this problem because I have no more access to the platform onto which I've tried LXC and on addition the Nova RC-1 version and Ubuntu 11.10 are now obsoletes.
So you can close this problem.
