[openstack-dev] [Neutron] [neutron-lib] adding a new flag to neutron-lib
Hi All I have added a new flag in neutron-lib https://review.openstack.org/#/c/291641/3/neutron_lib/constants.py and wanted to use that flag in neutron's change https://review.openstack.org/#/c/291651/ How to add the dependency? I added neutron-lib change in neutron's change as "Depends-On:" in commit message. Also added the change suggested in https://wiki.openstack.org/wiki/Neutron/Lib as "Depends-On:" in commit message. But still neutron change is not resolving the flag added in neutron-lib.

Re: [openstack-dev] [Neutron] DVR + L3 HA + L2pop - Mapping out the work
Hi Assaf I will work on this bug(i.e L3 HA integration with l2pop. I have already assigned it to myself). https://bugs.launchpad.net/neutron/+bug/1522980 Thanks Anil On 12/05/2015 04:25 AM, Vasudevan, Swaminathan (PNB Roseville) wrote: Hi Assaf, Thanks for putting the list together.

DVR has its share of problems, and this is being tackled full on, with more folks joining the good fight soon. L3 HA also has its own problems: * https://review.openstack.org/#/c/238122/ * https://review.openstack.org/#/c/230481/ * https://review.openstack.org/#/c/250040/ DVR requires l2pop, and l2pop on its own is also problematic (Regardless if DVR or L3 HA is turned on). One notable issue is that it screws up live migration: https://bugs.launchpad.net/neutron/+bug/1443421. I'd really like to see more focus on Vivek's patch that attempts to resolve this issue: https://review.openstack.org/#/c/175383/ Finally the way L3 HA integrates with l2pop is not something I would recommend in production, as described here: https://bugs.launchpad.net/neutron/+bug/1522980. If I cannot find an owner for this work I will reach out to some folks soon. __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
Re: [openstack-dev] [Neutron] need help in translating sql query to sqlalchemy query
Thanks Sean. I will check that. Meanwhile I tried this and it is working port1 = orm.aliased(models_v2.Port, name="port1") port2 = orm.aliased(models_v2.Port, name="port2") router_intf_qry = context.session.query(RouterPort.router_id).join((port1, port1.id==RouterPort.port_id), (port2, port2.device_id==RouterPort.router_id)).filter(port1.network_id==int_net_id, port2.network_id==ext_net_id).distinct() for router in router_intf_qry: router_id =router.router_id Thanks Anil Venkata On 12/01/2015 06:35 PM, Sean M.

My only suggestion would be to try and see if you can just alias it once, instead of twice. Basically see if it is possible to replace all the port1 references with "models_v2.Port" Thanks Sean. Sure, I will try that suggestion. __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
[openstack-dev] [Neutron] need help in translating sql query to sqlalchemy query
Hi All I have the below sql query which - "lists routers connected to given internal and external networks" select DISTINCT routerports.router_id from routerports inner join ports as ports1 on (ports1.id=routerports.port_id and ports1.network_id=internal_network_id) inner join ports as ports2 on (ports2.device_id=routerports.router_id and ports2.network_id=external_network_id); In the above query I am joining port table to routerport table twice. Can someone help me in translating that to SQLAlchemy query? This is required for the change https://review.openstack.org/#/c/220135/2/neutron/db/l3_db.py (see review comments) Thanks Anil Venkata __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
[openstack-dev] [neutron] [floatingip] Selecting router for floatingip when subnet is connected to multiple routers
Hi All I need your opinion on selecting router for floatingip when subnet is connected to multiple routers. When multiple routers connected to a subnet, vm on that subnet will only send packets destined for external network to the router with subnet's default gateway. Should we always choose this router(i.e router with subnet's default gateway) for floatingip? We have two scenarios - 1) Multiple routers connected to same subnet and also same external network. In this case, which router should we select for floatingip? Choose first router in db list or router with default gateway. What if router with subnet's default gateway not present? 2) Multiple routers connected to same subnet and different external networks. In this case, user has the choice to create floatingip on any external network( and on the router connected to that external network). But this router may not be the one having subnet's default gateway. Should we allow this?
