Fuel for OpenStack

How to modify a config file using Fuel Plugin

Asked by Jiahao liang

Hi community,

I am just new to Fuel plugin.

What I am trying to do is pretty straightforward. Let's say there is a line in <neutron.conf>
...
item1=value1
...

I would want to find value1 of item1 in neutron.conf and write them in <myconfid.conf> like this
...
item2=value1
...

Could any of you provide some references for me about how tot do that?

Thank you so much in advance.

to capture traffic in 'Neutron with tunneling segmentation' env you need to use open vswitch port-mirroring.here is how:
ip link add type veth
ip link set veth0 up
ovs-vsctl add-port br-tun veth0
ovs-vsctl -- set Bridge br-tun mirrors=@m -- --id=@veth0 get Port veth0 -- --id=@patch-int get Port patch-int -- --id=@br-tun get Port br-tun -- --id=@m create Mirror name=veth0 select-src-port=@patch-int,@br-tun select-dst-port=@patch-int,@br-tun output-port=@veth0

then tcpdump -i veth0

Can you help with this problem?
