KLuka_Hi guys... Do you have any idea if "OpenStack NFV Orchestration Using Tacker" presentation video will be available on https://www.openstack.org/summit/tokyo-2015/videos/?09:58
karimbKLuka_ probably yes10:07
karimbmost summit videos are10:07
ilozgachHello! Can anyone answer my question?10:17
ilozgachI want to implement custom management driver for my VNF.10:17
ilozgachAs it done, for example for OpenWRT10:18
ilozgachBut stevedore.extension do not see it10:19
ilozgachHow I can register my extension?10:19

tbharathilozgach, Hi, sorry for the late response11:06
tbharathilozgach, do you get any  errors?11:06
ilozgachMoment11:07
ilozgachIt looks like I found smth11:07
*** testss has quit IRC11:07
ilozgachWow11:10
ilozgachIt looks like I did it!11:10
ilozgachAfter 6 hours I did it :)11:11
tbharathilozgach, oh nice11:11
tbharathilozgach, may I know what is the issue you faced, and how you solved it?11:12
ilozgachWell, I think someone shold write "howto" for this task on tacker wiki11:12
ilozgachYes11:12
ilozgachI create file with name "nfvpilot" in directory /opt/stack/tacker/tacker/vm/mgmt_drivers/11:12
ilozgachups11:12
ilozgachname is "nfvpilot.py"11:12
ilozgachAnd implemented custom driver there11:13
ilozgachBut it was not visible11:13
ilozgachAfter long debbuging I found11:13
KLuka_karibm thanks11:13
ilozgachWiki page that says I have to update setup.cfg file11:14
ilozgachSo I did it but no luck11:14
ilozgachThen I updated /etc/tacker/tacker.conf file11:14
ilozgachBut no luck again11:14
ilozgachThen I found that NamedExtensionManager doesn't import my extension11:15
ilozgachThen I updated /opt/stack/tacker/tacker.egg-info/entry_point.txt file11:15
ilozgachAnd now it's loaded! :)11:16
ilozgachSo now I'm going to check how my manager configures VNF :)11:16
*** openstackgerrit_ has quit IRC11:16
tbharathilozgach, sure, I think Bob has mentioned this details as reply to your email11:18
tbharathilozgach,  we will update the wiki on how-to11:18
KLuka_From this review for http ping you can see what needs to be done: https://review.openstack.org/#/c/229858/11:19
tbharathKLuka_, Hi, I am not sure to whom you are referring the patch11:20
KLuka_This patch shows how to add new monitor driver, which is similar to adding mgmt driver. At least I think so :)11:21
tbharathKLuka_, I think you are trying  to refer this https://review.openstack.org/#/c/226899/7/doc/source/devref/monitor-api.rst11:23
tbharathKLuka_, yeah there we didn't specify the entry in entry_point.txt, we need to update the doc11:24
tbharaths/yeah/even11:25
KLuka_Maybe entry_point.txt is updated if you run setup.py install?11:26
tbharathKLuka_, yes11:27
tbharathKLuka_, but after you run setup.py, and you added monitor_driver or mgmt_driver11:28
tbharathKLuka_, either we have to update setup.cfg and run setup.py again11:28
tbharathKLuka_,  or update entry_point.txt11:28
KLuka_aha, thanks :)11:29
ilozgachAnyway, more details have to be added to wiki page11:29
ilozgachAt least specify that setup.py should be executed11:29
tbharathilozgach, yes11:29
tbharathKLuka_, in the second case, we have to restart again11:30
KLuka_Do we have to add driver name also to etc/tacker/tacker.conf and restart tacker service?11:32
KLuka_This is also not mentioned in monitor-api.rst...11:32
tbharathKLuka_, actually, we have to update what are the available drivers in /etc/tacker/tacker.conf for example monitor_driver=http_ping11:35
tbharathKLuka_, and then in setup.cfg or entry_point.txt, we need to map http_ping to python class for example11:36
tbharathKLuka_, http_ping = tacker.vm.monitor_drivers.http_ping.http_ping:VNFMonitorHTTPPing11:36
tbharathKLuka_, yeah will update as soon as possible11:37
*** dkusidlo has joined #tacker11:39
ilozgachInteresting thing that11:44
ilozgachI tried to vnf-create a lot of times before success11:45
ilozgachAnd now11:45
ilozgachI see that all failed attempts actually create VNF11:45
ilozgachBut it keeps in PENDING_CREATE state11:45
ilozgachForever11:46
ilozgachWhile vnf-create command produced internal server error11:46
ilozgachIs that expected behaviour?11:47
ilozgachAre you there?12:05
ilozgachI have new question :)12:05
KLuka_tbharath: great, thanks for your help12:05
ilozgachI have VNF which is in PENDING_UPDATE state, how I can modify it's state or remove it?12:06
KLuka_ilozgach, I am here but I don't think I can help you... Can you remove individual instances and than delete VNF?12:09
ilozgachI'm trying to perform command12:09
ilozgachtacker vnf-delete 082cf40a-0223-4c27-bbf4-74d8d3f2721e12:10
ilozgachBut it says12:10
ilozgachDevice 082cf40a-0223-4c27-bbf4-74d8d3f2721e is still in use12:10
ilozgachSo it's completely freezed12:10
KLuka_hat does tacker vnf-show  082cf40a-0223-4c27-bbf4-74d8d3f2721e outputs?12:12
KLuka_*what12:12
ilozgachAs usual, it shows VNF information12:13
ilozgach| description | demo-example12:14
ilozgachUps12:14
ilozgachIt looks like I cannot copy-paste here12:14
tbharathilozgach, can you paste tacker logs?12:15
tbharathilozgach, using paste.openstack.org12:15
ilozgachMoment12:16
*** KLuka__ has joined #tacker12:17
*** KLuka_ has quit IRC12:18
ilozgachDo you want logs for delete action?12:19
karimbhi foks, is this mandatory for tacker to create the heat stacks in the services tenant?12:22
karimbit got me crazy until i figured out the stacks were actually created, but not in the tenant i would have expected12:22
ilozgachtbharath, here it is http://paste.openstack.org/show/477456/12:23
tbharathilozgach, can I find the logs when you ran vnf-create?12:25
tbharathilozgach, when the vnf status is PENDING_CREATE, we cannot delete that vnf becuase it has a lock12:26
ilozgachI think the problem is in vnf-update that I performed with my custom mgmt_driver. That command failed. So after rhis command VNF get PENDING_UPDATE state12:28
ilozgachSo I just want to remove it or revert last vnf-update command. Is that possible?12:28
