This was originated because theTelco requirements I have described there. The implementation will reside in the OpenStack. So we are looking the problem described, what else operators need and then how to accomplish that. Most probably looking a new tool instead of injecting any existing. Tomi

The overall requirements are being reviewed in https://etherpad.openstack.org/p/AUS-ops-Nova-maint. A future tool may make its way in OSOps but I think we should keep the requirements discussion distinct from the available community tools and their tool repository. Tim From: Joseph Bajin mail

Rob/Jay, The use of the OSOps Working group and its repos is a great way to address this.. If any of you are coming to the Summit, please take a look at our Etherpad that we have created.[1] This could be a great discussion topic for the working sessions and we can brainstorm how we could help w

Hello Operators, one of the users of our cluster opened a ticket about a snapshot corner case. It is not possible to snapshot a instance that is booted from volume when the instance is paused. So I wrote this patch, and from the discussion you can see that I learnt a lot about snapshots. https://r

Maybe a result of the discussion can be a set of models (let's not go so far as to call them best pracices yet :) for how maintainance can be done at scale, perhaps solidifying the descriptions Jay has above with the user stories Tomi described in his initial note. This seems like an achievable ou

Yes, there is an unfortunate possibility of confusion around the word 'subnet'. To some, that means a network segment, or VLAN, and to some that just means the specific IP subnet. Neutron takes the latter view, and treats multiple subnets as multiple IP ranges on the same VLAN (which Neutron calls

But if the subnets are on the same VLAN it should work. That's what that patch is designed for. There is (currently) an assumption in Neutron that subnets in the same network are on the same L2 segment. So if a VM wants to communicate with a VM in another subnet on the same network, it can cut out

Hi Neil, Well that explains... My networking setup does not conform to the commit message in such a way that there are multiple subnets on the network, however the instance does not have an IP address in all of them but only in one. I guess the only option for now is to patch this code, as a worka

Hi, We are running Liberty, with provider networks. We use the Neutron DHCP agent to configure IPv4 and IPv6 addresses for instances. This is all working great, however we sometimes need to put multiple subnets on one VLAN interface (for legacy reasons). This is in fact also working, however it co
