Re: [Rdo-list] Trying out Neutron Quickstart running into issues with netns (l2 agent and dhcp agent)

Since l3 agent and dhcp agent in RDO are not right (they comment out ovs_use_veth=True and veths are required for the netns support in RHEL kernels) marun summarized this nicely: "if ovs_use_veth is set to false, a regular interface and an internal ovs port will be used, and the regular interface will be moved to a namespace during setup. if ovs_use_veth is set to true, a veth pair will be used with one endpoint created in the namespace. it is a limitation of rhel's netns implementation that requires the second approach, as virtual interfaces can only be created in namespaces, not moved post-creation." With manually enabling ovs_use_veth=True for l3 and dhcp agents, I was able to get cirros VM to get an ip address on launching. What doesn't work now is pinging/sshing to the floating ip address from the host (which is itself a VM) Yes, I did open those ports in the default security group, and I also made sure the instance was launched with the default security group. But that being said, I wanted to check the logs to see if some of the previous errors went away. dhcp-agent and l3 agent logs look clean now (aside from the amqp initial connection errors) My next test will be to run this exact same scenario but with NetworkManager disabled.
