sean-k-mooneybauzas: so much for fiber solveing all your internet problems11:09
kashyapsean-k-mooney: Don't rub it in :D11:11
bauzassean-k-mooney: given we have FTTH connections for optic fiber, that means any neighbor fiber needs to be going to an central office11:12
sean-k-mooneyyep11:13
sean-k-mooneyis it actrully your fiber connectivy that is havving issues or is it just something simple like dns11:13
sean-k-mooneywhere you can just use a different dns provider11:13
bauzassean-k-mooney: and sometimes, when a new customer wants to have a fiber ISP, the operator needs to go to the office to take the fiber and then fix it to the DSLAM11:14
bauzassean-k-mooney: so I think I had problems because the guy was workin on the DSLAM11:15
bauzas(I mean the cabinet)11:16
sean-k-mooneythey tend to set it up slightly differntly here.11:16
sean-k-mooneyya so FTTH at least where i am youhave a direct connection to an aggreation site (it can be a cabinet but ussually larger) and the tehy use a fiber switch to connect you to a a backhaul network11:17
bauzassean-k-mooney: in my department, the operator uses a p2p network for fibers11:17
bauzaseach fiber goes to the DSLAM11:18
sean-k-mooneyso if my neighbour is getting fiber installed it should not affect me as that will go over its own direct conencted fiber line to the aggreation point11:18
bauzasbut in Grenoble (which is in my department but has other operators), it mixes fibers *before* the DSLAM11:18
bauzasso, our development is better, as any fiber isn't mixed11:19
bauzasand we don't have equipments between my own fiber and the DSLAM11:19
bauzasbut that also means that if we have problems on the fiber itself, or at the DSLAM, then I'm impacted11:20
sean-k-mooneyya in ireland all the fiber is own by eirgrid and they do direct connection to houses but then aggreate mutiple frequense over the same fiber link only after that11:20
artom_I thought DSLAM was for DSL11:20
sean-k-mooneyi belive there is an optical version of it too that 11:22
bauzassean-k-mooney: sorry, I only know the french terms, but do you know whether the fibers are mixed between the ISP and your home or not ?11:22
sean-k-mooneydslam is the acronmy for the copper dsl version11:22
bauzassorry, french terms here https://lafibre.info/gpon/comprendre-les-differences-entre-la-fibre-gpon-p2p-active-ethernet-fttla/11:22
bauzasgpon fiber vs. p2p fiber11:23
bauzasie. we don't have with p2p fiber some cabinets in the streets for mixing fibers11:23
sean-k-mooneybauzas: all our fiber is manage seperatly form the isps and there is no mixing between me and then first level aggration site so my fiber link goes dirctly to a fiber switch11:24
bauzaswe have straight large optic cables that can take 800 lines each 11:24
bauzassean-k-mooney: ok so like me11:24
bauzasbut yeah, here is the same11:24
sean-k-mooneyso as long as the uplinks to that switch are not messed with my neigbors can get fiber installed lighting up one of the dark strands without impact11:25
bauzasone operator is responsable for managing a city network 11:25
sean-k-mooneyif that switch dies we all get taken out11:25
bauzasand then ISPs are only responsible for the connectivity to the last mile11:25
bauzasoh wait, then you have active internet ftth11:26
bauzasa local switch located in a street cabinet11:26
sean-k-mooneyits within 10km or so11:26
opendevreviewLee Yarwood proposed openstack/nova master: Add two new hacking rules  https://review.opendev.org/c/openstack/nova/+/80566811:27
sean-k-mooneybut ya it depends on desity where i am its likely closer due to the population desity11:27
bauzasvery interesting11:27
bauzasI'm afraid to only knowing french terminologies11:28
bauzasbut at least, I know my SPOFs11:28
sean-k-mooneyi did not see a fiber cabinet comming into where i live but there is likely one on the road within a km or so11:28
bauzasthat's something you should take interest11:29
bauzasas for example, depending on the deployment technology, you could be limited with bandwitdh upgrades11:29
bauzasie. a GPON FTTH is limited because this is mixed11:30
bauzasyou can only adress 2.5 Gbps per client11:30
bauzaswhile with P2P, changing the bandwidth is only an ISP question11:31
gibiwho needs more than 2.5 Gpbs?11:31
sean-k-mooneybauzas: i think technially i can get 10G if i needed too although i might need to replace the optical terminator on my side11:32
bauzasgibi: :D11:32
sean-k-mooneythey are currently only trilaing grater then 1G is some areas11:32
sean-k-mooneyi dont think mine is one of them11:32
bauzasgibi: trust me, I'm sometimes exhausting my 1gbps connection11:32
gibiI know the joke about 64Kb but honestly 2.5Gpb?!11:32
gibibauzas: do you download to /dev/null? :D11:33
bauzasI'm tempted to choose another ISP that proposes 2.5Gbps on two NICs11:33
bauzasso I could load-balance11:33
bauzasgibi: heh, downloading is always greedy11:34
bauzasgibi: but funnily enough, I discovered after 20 ans what IO-bound means11:34
bauzas20 years*11:34
bauzasnow, I'm limited by my clients, not by my bandwidth11:34
sean-k-mooneyi used to have semetriic 1gbps but they apparenly only did that for an intoductray trial and dropped my upload to 200mb. i have my home cloud offline for the last while but i was actully ortinnaly more interestedin getting native ipv6 which my current isp does not have an more upload so i could host a few things here11:35
bauzassean-k-mooney: yeah, I'm lazy with moving to v611:35
bauzaswhile I should11:35
bauzasmy ISP is proposing it and I could manage it11:36
bauzasbut I'm still concerned by 6to411:36
sean-k-mooneyi used ot use hricane eltric to provide a tunnel for ipv6 but there latency has gone up recently so removed it about 2 months ago11:36
bauzasthat's the whole problem with v611:36
bauzasuntil the whole internet has moved, you'll face problems with 6 :(11:37
sean-k-mooneymy isp recentl up there price so im going to move before the end of the year but native ipv6 is on my list of things to look for11:37
sean-k-mooneybauzas: oh we have dual stack connectivity11:37
bauzashah11:37
sean-k-mooneythere is no ipv6 only isp in ireland11:37
sean-k-mooneymost are still ipv4 only some offer native ipv6 in addtion 11:38
gibiI can write to my m2 ssd with 290MB/s you 1Gpbs download means ~128MB/s writing so a 2.5 Gpbs download would be limited by the local disk receiving the write11:38
sean-k-mooneyone even give you native ipv4 and ipv6 without CGNAT on teh ipv4 side but they are $$$$11:38
bauzassean-k-mooney: we have one provider that proposes ipv6 native11:39
bauzasbut this is an option11:39
bauzasgibi: trust me, I know it ;)11:39
bauzasa classic dd works 11:40
bauzasbut when it's about collecting pieces from the internet and reassembling them on the fly, I'm 11:40
bauzas**really IO-bound, even with 1gbps :)11:40
gibiyeah I can imagine11:40
bauzasyeah, reading newsgroups takes time... :)11:41
bauzasanyway, the dudes probably have stopped to work at the network room11:42
sean-k-mooneygod i havent done that in at least a decade. i did for a short while in collage but never found it a good way to consume info11:42
bauzaslooks like my gitches are gone11:42

gibisean-k-mooney: fyi just got reported from downstream https://bugs.launchpad.net/nova/+bug/194232913:30
sean-k-mooneygibi: yep this is a know issue13:33
gibiis it an older bug report open for it I should duplicate to?13:34
gibiis there13:34
sean-k-mooneygood question tl;dr when drict physical supprot was added they did not add support for any move operations13:34
sean-k-mooneyso cold migration resize and shelve are all broken13:35
sean-k-mooneyi cant recall if i blocked it for live migration or if that is also affected13:35
sean-k-mooneywe have downstream bugs for this https://bugzilla.redhat.com/show_bug.cgi?id=174584213:36
sean-k-mooneyi dont see an upstream one linked so im not sure if we have an upstream bug but we have talked about it at the ptg before i think13:37
gibithanks13:38
sean-k-mooneyah yes line 420 https://etherpad.opendev.org/p/nova-xena-ptg13:41
opendevreviewMerged openstack/nova stable/victoria: Reproducer unit test for bug 1860312  https://review.opendev.org/c/openstack/nova/+/80284213:42
sean-k-mooneyno upstream links form ath either altough i did not include the downstreeam one so either but lets use your new one for now13:42
gibiohh cool, I have a very bad memory 13:44
sean-k-mooneythis has been on my todo list to fix evenuatlly but it keep getting pushed off. artom started fixing some of the degecases and we have resolved other incidnetally.13:45
sean-k-mooneyfor example live migration did not wrok because 1 the mac was not updated and 2 detach of PF was not implmented13:46
sean-k-mooneygibi: you fixed detach when you added sriov attach/detach supprot13:46
gibiyepp13:46
gibiand I see artom fixed the unshelve pci_slot case13:46
sean-k-mooneyyes13:46
sean-k-mooneyso we have been trying to fix the more commens cases first when we get time too work on bugs13:47
gibiI made TODO now on my side to look at the MAC update at some point13:47
sean-k-mooneyack, so it a general problem for all pf move operation including evacuate13:48
sean-k-mooneyas you noted we do update the neutron port on vm boot intially its just never done after that13:48
gibiyepp13:48
sean-k-mooneyso we need to add the same logic in all the places to update the neutron port mac13:48
sean-k-mooneythe problem is that that is not part of multipe port bidnign which makes it annoying13:48
gibiohh then live migration will be a special case13:49
kashyapgibi: Is it something recent - Zuul requires uBlockOrigin to be disabled?13:49
kashyap(And Privacy Badger)13:49
gibikashyap: didn't noticed yet13:49
sean-k-mooneyyep gibi  so if you work on this proably leave live migration till last13:50
gibisean-k-mooney: ack, good idea13:50
sean-k-mooneywe could add a api block noting its not implemented in the interim with a workaround flag to allow operators to renable it13:50
sean-k-mooneyits one of the things we disucssed downstream i just never got around to pusshing a patch13:51
gibiit is not utterly broken as we are not leaking resources or breaking the guest, so I would not block the operation13:51
sean-k-mooneywell actully it kind of is13:51
sean-k-mooneythe vm will migrate but it can cause other vms to fail to boot13:52
gibiwhy?13:52
sean-k-mooneywhen we release the PF on the source13:52
kashyapWhen I opened a Zuul URL to debug, it was asking me to "please try with disabling ad blocker".  /me tries.  It's iether that, or it's just a stable URL13:52
kashyaps/stable/stale/13:52
sean-k-mooneyif another vm in the same network is shcudled to the source node then it will get a mac conflict in neutron when it trys to update the mac13:52
sean-k-mooneygibi: also the vm that was migrate will not get an adress form dhcp proeprly13:53
gibiOhh so neutron will reject the AMC update13:53
gibi:/13:53
gibiOK then it is broken13:53
sean-k-mooneyyep 13:53

sean-k-mooneyso unless you are using static ips the vm that was migrated will be broken too13:53
gibikashyap: could paste a link you are strugling with?13:53
kashyapgibi: https://zuul.opendev.org/t/openstack/build/a4b92ce40be841eaaf3e97f00c39b4d413:54
kashyapgibi: It's from June, granted13:54
gibisean-k-mooney: ahh so the dhcp agent uses the port.mac to provide the ip13:54
kashyapProbably it just got garbage-collected13:54
gibikashyap: it is already gc-d13:54
gibikashyap: you need to recheck the patch13:54
kashyapYep13:54
sean-k-mooneygibi: yes and the port will have the mac of the new PF13:54
gibiyep I got it know13:55
gibithen Im OK to block the operation13:55
sean-k-mooneygibi: so either the dhcp server will not respond or it will get the wrong ip if you have moved several vms13:55

gibiI marked https://bugs.launchpad.net/nova/+bug/1942345 as xena-rc-potential as we regressed SRIOV PF detach in Xena15:41
sean-k-mooneyoh it broke ya that would be rc bug then15:42
sean-k-mooneyi might see if we can get this in whitebox ot try and test it eventually15:43
sean-k-mooneyunfortunetly we dont have a way to run against upstream with sriov currently15:43
gibiyepp, it would be nice to get automatic coverage of SRIOV ops as I'm lazy to run SRIOV tests manually in my lab env frequently15:45
gibiI discovered this by playing with the SRIOV migration MAC issue15:45
gibimelwitt: if you are up, do you have any opinion about https://storyboard.openstack.org/#!/story/2009159 and the related discussion happened yesterday on the weekly meeting?16:02

melwittgibi: oh sorry I had missed that. need to read it16:06
melwittgah this traceback formatting on storyboard -_-16:08

melwittI support that16:12
