Thanks... it works ok...

There is some kind of configuration for DNS too?? I change my DNS server in /etc/resolv.conf but some time later it goes back to the default one set by dsnmasq. :-( :-(

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. “

Subject: [Openstack] nova network external gateway

Hi:

I have installed Essex and I´m using vlan networking. 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...
