<div dir="ltr">Alvise,<div><br></div><div>You should probably use the openstack-operators mailing list. However, you already solved the first part of your problem, which was that the openvswitch servers weren't running. The problem you have now is that sudo isn't paying attention to the quantum sudoers file which you should be able to find in /etc/sudoers.d/quantum. You need to have a line in /etc/sudoers that looks like this:</div>
<div><br></div><div>#includedir /etc/sudoers.d<br></div><div><br></div><div style>If you don't, use visudo and add it. Alternatively you can just dump the contents of /etc/sudoers.d/quantum into /etc/sudoers. That should take care of things also.</div>
