You can try the solution proposed by Vish on February 23, 2012. Put the flag and the config file on the nodes with nova-network as they have dnsmasq running:
" Then you can use --dnsmasq_config_file=/path/to/config in that config file you can use: dhcp_opiton=3,<ip of router> to force vms to use your router as their gateway.

All virtual machines use the same vlan, but I want all of them use an external gateway, I mean, a real router of my network instead of a nova node. I have read about it and I have found a parameter named: dhcpoption=3,<gateway ip> but I don´t know where to put it. I know that dnsmasq loads it but... from where?? I did not find any dnsmasq.conf in my system and, in the other hand, I put it in my nova.conf file and nothing happened. Thanks in advance.... Good luck...
