I would guess it has to do with the sudo configuration on your system. Typically, when quantum is installed it uses a special program called "quantum-rootwrap" for sudoing, e.g.:</div><div style><br></div><div style>
sudo quantum-rootwrap ip netns exec ...</div><div style><br></div><div style><br></div><div style>Typically, when you install OpenStack from packages, it will configure sudo (/etc/sudoers or /etc/sudoers.d) to allow quantum-rootwrap to do passwordless sudo for commands needed by OpenStack. </div>

Hi everyone!<br>
I'm having a problem with Quantum and my recent installation of
Grizzly on Ubuntu 12.04.<br>
<br>
I have this Network topology:<br>
<br>
<img src="cid:part1.09000404.09060101@gmail.com" alt=""><br>
<br>
<br>
The Virtual Machine "Testing" take correctly the IP Address on the
Network that it was created. The problem here is that the Router
doesn't take the IP Address of the Subnet (In this case is 10.0.1.1
and 10.0.2.1). If I check the logs of Quantum, I found this errors
on dhcp-agent.log:<br>

It repeats several time (when I start up Quantum or when I create a
new virtual machine). If I try to do a ping to the "Gateway"
address, it doesn't response.<br>
On Quantum, the Gateways Interface are down:<br>

<br>
On Google, I see some similar errors, but not a real solution.<br>
<br>
Someone had this issue? How it was resolved?<br>
<br>
