| salv-orlando | lifeless: still around? | 08:24 |
| lifeless | salv-orlando: ayup | 08:24 |
| salv-orlando | lifeless: I pinged the ovs team regarding the ptmud issue. I think they've looked at the email thread; however they suggested you route the question to ovs-discuss | 08:25 |
| salv-orlando | as more people would be able to take a look there and give feedback. | 08:25 |
| lifeless | ok | 08:25 |
| lifeless | is there a neutron-er that will do that? | 08:26 |
| sandeepr | am doing baremetal provisioning, one of the things i was checking is pxe boot a vm to see if it receives a dhcp offer | 08:26 |
| salv-orlando | lifeless: ok, I will do that then ;) | 08:26 |
| sandeepr | however the vm does not get the dhcp offer | 08:26 |
| lifeless | salv-orlando: awesome | 08:26 |
| salv-orlando | if you don't see the email on ovs-discuss by tomorrow ping me again | 08:26 |
| lifeless | sandeepr: what are you using to do bare metal provisioning? How is the VM related to baremetal provisioning ? | 08:27 |
| lifeless | salv-orlando: cool | 08:27 |
| lifeless | salv-orlando: did you see | 08:27 |
| lifeless | https://bugs.launchpad.net/tripleo/+bug/1271344 | 08:27 |
| *** godara has quit IRC | 08:27 | |
| *** godara has joined #openstack-neutron | 08:28 | |
| sandeepr | lifeless, am using standalone vm controller/compute to do bm provisioning. the vm is just a test to see if it receives dhcp offer | 08:28 |
| lifeless | so the VM is standing in for real hardware? | 08:29 |
| sandeepr | yes | 08:29 |
| lifeless | how is the VM networking setup ? | 08:29 |
| salv-orlando | lifeless: hmmm, this sounds like a regression. I'll assign this to arosen, he has expertise with lease removal | 08:29 |
| lifeless | salv-orlando: I recall someone asking about this on either IRC or mailing list a few months back | 08:30 |
| lifeless | salv-orlando: so it may have been like this a bit | 08:30 |
| lifeless | salv-orlando: thank you! | 08:30 |
| lifeless | salv-orlando: I've got a few possible solutions outlined ;) | 08:30 |
| sandeepr | the flat network is going through the same vswitch | 08:31 |
| lifeless | flat network ? | 08:32 |
| lifeless | sandeepr: assume we know /nothing/ about your setup | 08:32 |
| *** godara_ has joined #openstack-neutron | 08:32 | |
| sandeepr | e.g, dhcptest is a vswitch with no physical port attached. | 08:32 |
| sandeepr | am coming there :-) | 08:32 |
| *** godara has quit IRC | 08:32 | |
| sandeepr | eth1 of controller/compute and eth0 of the target vm is connected to the dhcptest vswitch | 08:33 |
| *** emagana has quit IRC | 08:33 | |
| lifeless | ok, this is sounding like the tripleo devtest environment to me :) | 08:33 |
| sandeepr | hehe | 08:33 |
| *** dave_tucker is now known as dave_tucker_zzz | 08:34 | |
| lifeless | anyhow, if it is, and it was setup by our automation, it should be wired up correctly | 08:35 |
| lifeless | make sure the vm is set to attempt PXE boot | 08:35 |
| lifeless | and make sure the mac address registered in nova baremetal is correct | 08:35 |
| sandeepr | yes the vm pxe boots and fails with no dhcp offer | 08:35 |
| lifeless | neutron's dhcp server won't answer at all to unknown macs | 08:35 |
| *** dave_tucker_zzz is now known as dave_tucker | 08:36 | |
| lifeless | on the controller there will be a netns with the dhcp server running in it | 08:36 |
| sandeepr | correct, i registered the vm and created a port as well | 08:36 |
| *** godara has joined #openstack-neutron | 08:36 | |
| lifeless | you can run | 08:36 |
| *** godara_ has quit IRC | 08:36 | |
| lifeless | ip netns exec <dhcp-uuid> tcpdump -nlpi tap-uuid port bootps or port bootpc | 08:37 |
| lifeless | to see the traffic | 08:37 |
| *** iwamoto has quit IRC | 08:37 | |
| lifeless | if you don't see the request, move the tcpdump closer to the vswitch | 08:37 |
| lifeless | until you find it, then you know where the misconfiguration is | 08:37 |
| lifeless | if you see the request, check syslog on the controller | 08:37 |
| lifeless | someting like | 08:37 |
| sandeepr | i doubt if its a misconfig | 08:37 |
| salv-orlando | lifeless: as I recall, dnsmasq needs a DHCPRELEASE to get rid of an in-memory lease before its expiration. We're triggering it on port_delete. This is why I was mentioning a possible regression | 08:38 |
| salv-orlando | this is the original commit: https://github.com/openstack/neutron/commit/d9832282cf656b162c51afdefb830dacab72defe | 08:38 |
| sandeepr | because when i launch an instance that works seamlessly | 08:38 |
| sandeepr | i'm seeing the problem only when i created a blank vm and pxe booted it | 08:38 |
| lifeless | sandeepr: I'm confused, blank vm /pxe is *what* the nova-bm driver does | 08:39 |
| lifeless | sandeepr: what specifically do you mean by 'launch an instance' | 08:39 |

| salv-orlando | If the DHCPRELEASE is being sent it shows in syslog. If the message bus loses this you should not even if the lease file being updated, I think | 08:42 |

| salv-orlando | wow my last sentence was a bit messed up.. I wanted to say that if the message is dropped then the hosts file should not be updated as well | 08:43 |
| lifeless | salv-orlando: I only see two DHCPRELEASE messages in the entire syslog | 08:43 |
| lifeless | ah, lots more in syslog.1 | 08:44 |
| *** godara_ has quit IRC | 08:44 | |
| salv-orlando | lifeless: 'unknown lease' is interesting because it means the VM never took it in the first place. Might be unrelated and non-important however | 08:44 |
| lifeless | sandeepr: so please answer my question - what specifically do you mean by 'launch an instance' | 08:44 |
| salv-orlando | for instance the VM might have been killed before it even sent the DHCPDISCOVER | 08:44 |
| lifeless | salv-orlando: might be a side effect of my hack to restart on new allocations | 08:44 |

| sandeepr | lifeless, launch an instance = nova boot | 08:48 |
| lifeless | sandeepr: and what is it booting ? | 08:48 |
| lifeless | sandeepr: the PXE based VM ? or something else ? | 08:49 |
| sandeepr | lifeless, the pxe based vm | 08:49 |
| lifeless | sandeepr: ok, and so when you say 'made a blank vm and pxe boot it', do you mean you just made the vm and powered it on by hand ? | 08:49 |
| sandeepr | lifeless, exactly | 08:50 |
| lifeless | sandeepr: if so, of course it won't boot because no port has been created for it. | 08:50 |
| *** AlexF_ has quit IRC | 08:50 | |
| lifeless | sandeepr: to PXE boot with neutron you need a port created with an ip assigned and PXE port options set, plus you need a tftp server with the kernel ramdisk etc to boot it | 08:51 |
| sandeepr | lifeless, yes i'm aware of it. hence i registered the vm and added its interface [nova baremetal-node and interface commands]. and then quantum port-create --mac-address | 08:51 |
| lifeless | sandeepr: all of that is setup when do you 'nova boot' | 08:51 |
| *** godara_ has joined #openstack-neutron | 08:51 | |
| sandeepr | lifeless, yes all of that is setup with nova boot | 08:51 |
| *** godara has quit IRC | 08:51 | |
| *** godara_ is now known as godara | 08:51 | |
| lifeless | ok, so I'm trying to understand your question :) It sounds like you are asking 'why when I don't use nova boot does the instance not PXE boot', and the answer is 'because you didn't use nova boot' | 08:52 |
| lifeless | :) | 08:52 |
| sandeepr | lifeless, rofl | 08:52 |
| lifeless | sandeepr: so can we narrow it down ? | 08:56 |
| lifeless | sandeepr: are you trying to replicate the nova-bm configuration by hand ? | 08:56 |
| sandeepr | lifeless, just the dhcp part | 08:57 |
| *** xuhanp has joined #openstack-neutron | 08:59 | |
| lifeless | so, make sure the port is on the right network, that the ip address is unique,the mac address matches the VM eth0, and that the dhcp port options have been set | 08:59 |
| lifeless | you can nova boot, capture the port details, then use that as a checklist | 09:00 |
| sandeepr | except the last one dhcp port options have been set, i know the rest is ok. how do i check this one? | 09:00 |
| lifeless | neutron port-show should show it | 09:00 |

| humbolt | roaet: I was wondering if I am on the right server. In #openstack there are over 800 people, but nobody ever seems to have anything to say. | 16:34 |
| humbolt | Anyhow, I need some guidance with Neutron. | 16:34 |
| roaet | Hrmm. well #openstack-dev is more active than #openstack | 16:34 |
| roaet | but in theory it shouldn't matter which server you're on as long as it is a freenode connected server. | 16:35 |
| humbolt | roaet: I would not dare to bother devs with support like questions, unless a bug might be involved. | 16:35 |
| roaet | Ah. Well this channel is primarily a dev channel. | 16:35 |
| roaet | BUT | 16:35 |
| roaet | I am happy to try to help you with neutron issues. | 16:35 |
| roaet | :) | 16:35 |
| humbolt | roaet: alright, have never read up on IRC protocol, so I was never sure. | 16:36 |
| roaet | humbolt: yeah all the 'servers' connected to the network share the info most of the time. | 16:36 |
| *** therve has left #openstack-neutron | 16:36 | |
| roaet | Sometimes they split up (netsplit) but that is pretty rare unless there is an incident (DDoS) | 16:36 |
| humbolt | As far as Neutron is concerned, I need some general guidance. | 16:37 |
| humbolt | roaet: ok, get it. | 16:37 |
| roaet | Would you mind describing your use-case? | 16:37 |
| roaet | Are you playing with openstack for knowledge sake? Migrating from nova-network? | 16:37 |
| humbolt | I'd love to. | 16:37 |
| humbolt | I did an openstack/ceph installation with grizzly to educate myself. Networking was based on nova-network VLAN manager. Everything worked fine. Now I did a fresh install to go into production with this cloud and now I am at the point, where I have to decide, whether to go down the Neutron road or not. | 16:39 |
| *** thedodd has joined #openstack-neutron | 16:40 | |
| roaet | Well, I am slightly biased as far as that question (being a neutron dev), but it appears the general direction of openstack is to primarily support neutron as the networking platform of choice. | 16:40 |
| roaet | That is a slow process but it's happening. | 16:41 |
| humbolt | My cluster/cloud is minimal for starters, just 3 node to begin with. And I was planning to use all 3 as compute-nodes. There wont be much load on theses servers. | 16:41 |
| humbolt | roaet: right, that is why I would rather go down the Neutron road. | 16:41 |
| sc68cal | humbolt: We had a similar deployment at Comcast | 16:41 |
| roaet | The migration from nova-network to neutron is non-trivial. | 16:42 |
| sc68cal | And we moved from Nova-Network FlatDHCPManager, to Neutron OVS and vlans | 16:42 |
| roaet | If you do not mind losing data (all the things) then it's pretty trivial. | 16:42 |
| humbolt | Yeah, a later migration is what I am concerned about most. | 16:43 |
| sc68cal | (We originally used FlatDHCPManager and set VLANs up at the top of the rack) | 16:43 |
| humbolt | To my use case: | 16:43 |

| *** simon-AS559 has joined #openstack-neutron | 16:55 | |
| roaet | humbolt: depending on which plugin you use you can find the use-case you've talked about somewhere in here: http://docs.openstack.org/admin-guide-cloud/content/ch_networking.html | 16:56 |
| roaet | I am looking for it but pipelining the search seems nice :D | 16:56 |
| roaet | I believe Networking Scenarious > Plugins > Scenario # would be what you're looking for | 16:58 |
| roaet | I was told, by the person who wrote the doc, that such a configuration you mentioned existed in there | 16:58 |
| *** simon-AS5591 has quit IRC | 16:58 | |
| roaet | I didn't write the docs myself though :( | 16:58 |
| roaet | Backend is the plugin, my apologies. | 16:58 |
| *** AlexF_ has quit IRC | 16:59 | |
| humbolt | which plugin would you recommend there?! | 17:00 |
| roaet | OVS plugin I know works. | 17:00 |
| roaet | With your desired setup | 17:01 |
| roaet | They should all theoretically work the same though. | 17:01 |
| roaet | It just depends on your scale. | 17:01 |
| roaet | Most of my experience with plugins are OVS or NVP. | 17:02 |
| humbolt | OK, I go with the open source one ... | 17:04 |
| roaet | Tis a good choice :D | 17:04 |

| *** AlexF_ has quit IRC | 17:10 | |
| gpza | I'm working on a hypervisor with my professor and we're trying to write an openstack nova plugin (this will likely never be merged in). I want to make sure I implement everything necessary for neutron networking support | 17:12 |
| *** shivharis has quit IRC | 17:12 | |
| *** shivharis has joined #openstack-neutron | 17:12 | |
| gpza | the hypervisor can create a tap interface for each specified virtual interface, but I don't yet understand what I need to do with this tap interface. Is it as simple as attaching it to the integration bridge? | 17:12 |

| humbolt | roaet: What I am actually most concerned about is, that I do not have a lot of NICs in my nodes. | 17:21 |
| *** shivharis has quit IRC | 17:22 | |
| humbolt | roaet: eth0 is in shared use with HP iLO their IPMI implementation, so I do not really make use of it, as its work is interrupted by IPMI. | 17:22 |
| humbolt | roaet: eth1 is for internet connectivity | 17:23 |
| *** mestery_ has joined #openstack-neutron | 17:23 | |
| humbolt | roaet: eth2 so far I have used for VLAN interfaces | 17:23 |
| humbolt | roaet: and eth3 is used for CEPH backbone communication exclusively. | 17:23 |
| humbolt | roaet: So I am not sure, if I can even set Neutron up as I read there is a 3 NIC requirement. | 17:24 |

| marun | markmcclain: I have a few questions :) | 18:46 |
| *** rkukura has quit IRC | 18:46 | |
| markmcclain | marun: ask away :) | 18:47 |
| marun | markmcclain: first, are there any plans yet in place to migrate from in-tree rpc to oslo.messaging in the icehouse timeframe? | 18:47 |
| markmcclain | it's been on the long term plan, but wanted to get more stability and testing ebfore we switched | 18:47 |
| markmcclain | are you volunteering? :) | 18:47 |
| marun | markmcclain: whether me or no, it's looking like it's a priority for rh so we would likely be willing to devote resources. | 18:48 |
| markmcclain | awesome | 18:48 |
| markmcclain | I'd like to move to oslo.messaging | 18:49 |
| marun | markmcclain: are there any roadblocks to making the switch? And presumably the sooner the better so we can iron things out? | 18:49 |
| markmcclain | the only real road block is the same problem we've had to for 2 wks | 18:49 |
| markmcclain | the kernel issues that are preventing us from running any tests | 18:49 |
| openstackgerrit | Sylvain Afchain proposed a change to openstack/neutron: Test patch, do not review https://review.openstack.org/68483 | 18:50 |
| markmcclain | those problems have made it impossible to get any repeatable test results | 18:50 |
| marun | markmcclain: ok. I'll communicate as much to folks at rh and see about resourcing. | 18:51 |
| marun | markmcclain: wrt the gate issues, is there any room for help? | 18:51 |
| marun | markmcclain: I haven't been able to reproduce :( | 18:51 |
| markmcclain | yeah only seems to show up with 3.2.0-58 kernel we run in the gate | 18:51 |
| *** safchain has quit IRC | 18:52 | |
| markmcclain | the kernel is old and we're working on updating the checks to use a newer kernel | 18:52 |
| *** jamespage_ has joined #openstack-neutron | 18:52 | |
| marun | markmcclain: i hear there is an experimental job with a newer kernel, any success? | 18:52 |
| markmcclain | I've been working on testing with it this morning | 18:52 |
| markmcclain | had to make a few tweaks | 18:52 |
| anteaya | there is a patch in experimental right now | 18:53 |
| anteaya | tests are running | 18:53 |
| marun | ok | 18:53 |
| markmcclain | I'm hopeful the kernel upgrade will fix the problem for now | 18:54 |
| markmcclain | long term we will need a solution that works with the kernel in 12.04 for some time | 18:54 |
| *** clev has quit IRC | 18:55 | |
| marun | markmcclain: *cough* just don't use the open source option *cough* | 18:55 |
| * marun runs and hides | 18:55 | |
| marun | markmcclain: ok, on a different tact, I've been thinking about nova+neutron coordination to avoid races. | 18:55 |
| markmcclain | yes | 18:55 |
| *** anteaya sets mode: -o anteaya | 18:56 | |
| marun | markmcclain: from what I know, nova network doesn't risk races between network configuration and vm boot by performing the configuration synchronously. | 18:56 |
| marun | markmcclain: What do you think about nova doing a check during vif plug (right after plugging the vif into the ovs bridge)? i.e. calling neutron and verifying that the port is ready? | 18:57 |
| markmcclain | that's possible | 18:58 |
| markmcclain | I know arosen has some ideas too | 18:58 |
| marun | markmcclain: It would require the l2 agent to report on whether the port is wired so it can be saved in the db for the neutron service to report back to nova | 18:58 |
| marun | markmcclain: and the dhcp agent to report when an address has been configured to be served | 18:59 |
| marun | markmcclain: is there any tracking of this per-port status at present? | 18:59 |
| markmcclain | yeah.. having DHCP report would require a lot more coordination | 18:59 |
| *** jamespage_ has quit IRC | 18:59 | |
| markmcclain | that can be eventually consistent | 18:59 |
| marun | markmcclain: why would it require more coordination? | 18:59 |
| markmcclain | neutron server doesnt really track DHCP update state | 19:00 |
| marun | markmcclain: ah, ok. | 19:00 |
| marun | markmcclain: so it would be necessary to both track and then update the db state | 19:00 |
| *** jecarey has joined #openstack-neutron | 19:00 | |
| marun | markmcclain: ok, so food for thought. | 19:00 |
| *** Ric_ has quit IRC | 19:00 | |
| markmcclain | yeah there are lots of ways to fix things | 19:01 |
| marun | markmcclain: is it in the realm of possibility to have done in icehouse, at least as a configurable option? | 19:01 |
| marun | markmcclain: I just want one :) | 19:01 |
| marun | markmcclain: the point is, neutron can't be as reliable as nova network unless a check is done pre-boot | 19:01 |
| markmcclain | I'm doubtful that icehouse is possible | 19:01 |
| markmcclain | remember the feature proposal deadline is Feb 18th | 19:02 |
| marun | markmcclain: eek | 19:02 |
| markmcclain | that is a really short timeline | 19:02 |
| markmcclain | and we've got a decent backlog of items to clear | 19:02 |
| *** rohit404 has quit IRC | 19:02 | |
| marun | markmcclain: and how many of them are as important as this? | 19:02 |
| marun | markmcclain: (or maybe this isn't important) | 19:03 |
| markmcclain | many of the items are important because they are stability items | 19:03 |
| marun | markmcclain: fair enough. | 19:03 |

| markmcclain | arosen should be there too | 19:05 |
| marun | markmcclain: Ok. Would it be possible for someone from rh to attend? | 19:06 |
| markmcclain | yeah the meetup is open | 19:06 |
| marun | markmcclain: ok. | 19:06 |
| markmcclain | should already be a few RH folks there… I know Russell will be there | 19:06 |

| rohit404 | hi markmcclain, with the agent scheduler (better knobs in icehouse) feature in Neutron, there can be multiple L3 agents for a single tenant router resulting in a multi-host mode similar to nova-network….i want to check if my understanding is correct here ? | 19:21 |
| markmcclain | rohit404: just failover not bandwidth benefits | 19:27 |
| marun | shashank_: what is the actual import error? | 19:27 |
| marun | shashank_: if your tox env is whacked, have you run tox -r to ensure the venv is rebuilt? | 19:28 |
| rohit404 | markmcclain: ah right, the multi-host also allowed to use the nova-network on the host that had the tenant VM running. | 19:30 |
| marun | markmcclain: what exactly is a prt binding? | 19:30 |
| marun | markmcclain: sorry, port binding | 19:30 |
| markmcclain | marun: it is the details to take a neutron port and bind it to the device on the hypervisor | 19:31 |
| marun | markmcclain: what kind of details? and when do they become available? | 19:32 |
| marun | markmcclain: I'm seeing things like host id but I'm a bit confused as to when that would be known. | 19:32 |
| marun | markmcclain: is it known where a port will be allocated at creation/ | 19:33 |
| marun | ? | 19:33 |
| markmcclain | once you know which host it is on you can give details to bind | 19:33 |

| carl_baldwin | markmcclain: ping | 22:56 |
| annegentle | emagana: sorry about that. We had issues with the "on air" so we just did a normal hangout after 3 tries | 22:56 |
| markmcclain | carl_baldwin: pong | 22:56 |
| carl_baldwin | Do you recall the netns multitool idea we discussed? I'm getting around to playing around with it today. | 22:57 |
| carl_baldwin | I started playing with doing it in python hoping maybe to leverage existing code by importing. However, importing anything useful adds many 100s of ms to the startup time of the utility. Kind of defeats the purpose. | 22:58 |
| carl_baldwin | So, my question is does this utility necessarily need to be written in python or can bash be an option? Since python code can't really be imported, it might be more straightforward to write a bash script and would likely startup faster. | 22:59 |
| *** yfried has quit IRC | 23:00 | |
| markmcclain | ideally python | 23:00 |
| carl_baldwin | markmcclain: that's all | 23:00 |
| markmcclain | but I think we might have iterate a bit and figure out what we want to support | 23:01 |
| markmcclain | we also have the ability to write a console script that is free of imports | 23:01 |
| *** armax has quit IRC | 23:02 | |
| zzelle_ | markmcclain, does it look strange to have multiple type drivers for the same type (like vlan) and choose the one you want to use through type_drivers option in ml2 conf file ? | 23:03 |
| *** clev has joined #openstack-neutron | 23:03 | |
| *** mfink has joined #openstack-neutron | 23:03 | |
| markmcclain | zzelle_: it can look strange | 23:03 |
| emagana | annegentle: I se.. its ok.. However, I will have a meeting this Friday with Nick and Phil to go over Neutron Docs | 23:03 |
| carl_baldwin | markmcclain: Right, I think that is the way to go to avoid the startup costs that would defeat the performance gains we're going for. | 23:03 |
| markmcclain | zzelle_: the main issue is making it clear why we need types with subtle differences | 23:04 |
| *** WackoRob_ has quit IRC | 23:04 | |
| zzelle_ | markmcclain, the aim is to allow to make segmentation_id optional for provider-network | 23:05 |
| carl_baldwin | markmcclain: I think I might prototype a proof of concept in bash so that I can quickly get an idea of the gains we can get from this approach. If it looks like the benefit is good, then I'll start a python console script. I just have the feeling that it will be a shell script written in python which I have never really liked much. | 23:05 |
| zzelle_ | but still allowing users to use the current implementation | 23:05 |
| markmcclain | carl_baldwin: yeah it is possible that we do write the tool in bash later on, but I'd like to look a initial dev work in python | 23:05 |
| carl_baldwin | When I submit a patch, I'll submit it in python. | 23:06 |
| markmcclain | carl_baldwin: ok that works.. yeah I agree python shell scripts usually look worse | 23:06 |
| carl_baldwin | markmcclain: thanks. | 23:06 |
| zzelle_ | markmcclain, but it will perhaps require to check at must on type driver is provided per network type | 23:08 |
| *** AlexF_ has quit IRC | 23:08 | |
| markmcclain | zzelle_: hmmm… how would the drivers be selected? | 23:11 |
| zzelle_ | through ml2 type_drivers option | 23:12 |
| markmcclain | so have variants with slight name differences? | 23:12 |
| zzelle_ | markmcclain, let me check, i am not sure of the option name | 23:12 |
| zzelle_ | markmcclain, exactly | 23:12 |

| *** jd is now known as Guest11536 | 23:21 | |
| Guest11536 | qq what is FWaas adding to security groups? If you add a rule in the firewall topen ssh do you still need to open the ssh port in security groups to ssh into the system? | 23:23 |
| zzelle_ | yes | 23:23 |
| Guest11536 | if you dont add the rule then all traffic should be blocked regardless of security groups correct? i am at a point where my environment has a firewall active but rules are ineffective ... | 23:26 |
| zzelle_ | AFAIK FWaaS aim does not depend on the compute techno (typically some vmware config does not support security groups) | 23:26 |
| *** jgrimm has quit IRC | 23:27 | |
| zzelle_ | yes | 23:27 |
| *** clev has quit IRC | 23:27 | |
| Guest11536 | ok ..so the only config needed is to enable the firewall in fwaas_driver.ini as well as add : service_plugins = neutron.services.firewall.fwaas_plugin.FirewallPlugin and service_provider=FIREWALL:Firewall:neutron.services.firewall.drivers.linux.iptables_fwaas.IptablesFwaasDriver:default to neutron.conf on the network node | 23:29 |
