Open Stack

Hi,

I'm having some trouble with getting a specified default route to the clients with Quantum, DHCP, dnsmasq and bridge mappings.
The DHCP config is created, the opts file has the following content:
tag:tag0,option:router,10.0.0.1

However, the tag option seems to prevent this from working.
The client get the IP of the dhcp server as the default route in stead of the config from the opts file.
(the quantum bridge mapping and dhcp itself work fine)
When I manually remove the "tag:tag0" from the opts file it starts working correctly.

Any clue what could be going on?
Does the tag setting belong in the opt file and if so, what could be preventing the gateway address from propagating to the client?

The setup is as follows:
* Quantum, bridge_mapping, Namespaces disabled
* Runs on Folsom, Scientific Linux 6.3 with openvswitch 1.7.1 kernel module

* quantum net-show
