I first, i apologize for my "so bad" english.

My problem is that dnsmasq assigns (with dhcp) to the lxc containers the 
value of "dhcp --listen-address " as dns nameserver.
I want to use another dns server in my local network
The solution is to use "--dhcp-option=6,192.168.X.X,192.168.X.X" in the 
dnsmasq command line. 6 is a tag indicating the DHCP option dns-server
Now the file /etc/resolv.conf of my containers are properly informed.
