BTW. I also restart the network service to be sure that any previous
configuration is completely removed.

Subject: [Openstack] [devstack/quantum] Configuration issue
Hi,
This morning I encountered a problem (which did not happen a few days
ago :)). When devstack is launched, with quantum configured, the gateway
and bridge devices are created. This causes problems with quantum.
For example when devstack is up and running prior to deploying an
instance we have:
brq744ec2f4-c0 Link encap:Ethernet HWaddr fa:16:3e:03:a6:55
inet addr:10.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

inet addr:10.0.0.1 Bcast:10.0.0.255 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:500
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
When an instance is deployed the following happens:

My guess is that this can be solved with the nova configuration. Sadly I
am not too familiar with these. Any help would be great.
Thanks
