Hi Tomasz,
Thanks for your note. I am not sure I completely understand the problems you are facing. Please note that the patch you have referred to introduces the VIF-driver for Quantum’s Linux Bridge plugin. The behavior of this is slightly different from the VIF driver that is used within Nova for plugging into a Linux bridge (when using a VLAN-NetworkManager). More responses inline. Thanks, ~Sumit.

Could you kindly be a little more specific as to which MAC address needs to change, and is not getting changed?</Sumit> 2) nova-network is not initializing bridge devices on startup and l3 interfaces <Sumit> Did you run the Quantum Linux Bridge agent? The agent does this work, and it only happens when the first VM comes up on that network. </Sumit> 3) machine running instances after reboot is loosing all bridges and tap devices and there is no code which recreates this. <Sumit> I have not tested this, but again, if you were running the Quantum Linux Bridge agent, the bridges should get created again. The tap devices are created in the VIF driver, so that only happens when Nova calls “plug” on VM start-up. </Sumit> problem 1 and 2 is resolved by code changes in nova and problem nr. 3 is addressed by adapting interface type bridge with quantum linux bridge integration. patches are on launchpad https://bugs.launchpad.net/nova/+bug/941794 At the end in my opinion we don't need an agent for linux bridge integration. <Sumit> As I mentioned earlier, in order to fully support the Quantum attach/detach interface semantics, the interface-type has to be set to “ethernet” (so that tap devices can be used, and be added to the bridge only when attach is called, and vice versa), and the agent has to be run so that the per-host configuration is done correctly. So the agent is needed. Of course, if there are any issues, those need to be fixed.</Sumit> Dnia 20-03-2012 o godz. 22:29 "Sumit Naiksatam (snaiksat)" <snaik...@cisco.com> napisał(a): Hi Ghe, Thanks for this update. The Linux Bridge plugin also needs an agent. I would imagine that the packaging of that agent would be very similar to that of the openvswitch-agent, but I don’t know enough on the packaging to say with any certainty. Also, the Cisco plugin does not use an agent at this time, so no agent packaging is required there; just letting you know so that you don’t have to spend your time exploring. If I am not mistaken, the Ryu plugin also uses an agent. Thanks, ~Sumit.

You are therefore strongly encouraged to test and validate it. If you find an issue that could be considered release-critical, please file it at: https://bugs.launchpad.net/quantum/+filebug and tag it "essex-rc-potential" to bring it to Dan's attention. The "master" branch of Quantum is now open for Folsom development, feature freeze restrictions no longer apply. NB: Quantum is not a core project for the Essex cycle, therefore it's not part of OpenStack 2012.1 common release, scheduled for April 5. -- Thierry Carrez (ttx) Release Manager, OpenStack _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openst...@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Dan Wendlandt Nicira Networks: www.nicira.com twitter: danwendlandt ~~~~~~~~~~~~~~~~~~~~~~~~~~~ -- Mailing list: https://launchpad.net/~netstack Post to : netstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~netstack More help : https://help.launchpad.net/ListHelp -- Ghe Rivero OpenStack & Distribution Engineer www.stackops.com <http://www.stackops.com/> | ghe.riv...@stackops.com <mailto:diego.parri...@stackops.com> | +34 625 63 45 23 | skype:ghe.rivero <http://www.stackops.com/> <http://stackops.s3-external-3.amazonaws.com/STACKOPSLOGO-ICON.png> ******************** ADVERTENCIA LEGAL ******************** Le informamos, como destinatario de este mensaje, que el correo electrónico y las comunicaciones por medio de Internet no permiten asegurar ni garantizar la confidencialidad de los mensajes transmitidos, así como tampoco su integridad o su correcta recepción, por lo que STACKOPS TECHNOLOGIES S.L. no asume responsabilidad alguna por tales circunstancias.
