[Openstack] Fwd: Can't ping my VM after associating a floating IP address

Hi Sylvain,

Yes I managed to get l3-agent up and running. You were right it was a
problem of sudoers.
I didn't notice the files for cinder, quantum and nova in /etc/sudoers.d.

I still have an issue with dhcp-agent because a VM data IP address was
already taken. But
I think I can manage to solve it before I can ask for help.

I am using debian wheezy.

Thanks a lot for your help (merci beaucoup),
Amine.
