Since yesterday, we have a lot of network (2 per students , 100 students) , so a lot of errors:
In the log of dnsmask we can see this:
Apr  5 08:55:02 dnsmasq-dhcp[2466928]: read /var/lib/neutron/dhcp/7d33855e-03a8-431b-9cf8-64f8e95b8f93/host

Apr  5 08:55:05 dnsmasq-dhcp[4572]: DHCPDISCOVER(tap6fe70972-c9) fa:16:3e:6d:dc:c8 no address available


You say: If that's not it please file a new bug with all the above info provided.
How can I do that ?

Thanks a lot 

Franck
