hidekazuhi, I created environment via devstack and start using watcher.08:53
acabothidekazu : great, how is it going ?08:54
hidekazubut watcher action list returns no output after created audit.08:55
hidekazuI saw http://docs.openstack.org/developer/watcher/deploy/user-guide.html#getting-started-with-watcher08:55
hidekazuPlease help.08:56
vincentfrancoisehi hidekazu08:57
hidekazuhi vincentfrancoise.08:57
vincentfrancoisedo you mean you have no action in your action plan?08:58
hidekazuIn the user guide, "Wait until the Watcher audit has produced a new action plan, and get it", so i just waited.08:59
vincentfrancoiseoh ok, so you did "watcher actionplan list --audit <the_audit_uuid>" and you get nothing right?09:00
hidekazuyes.09:00
vincentfrancoisehidekazu: in that case, please run "watcher audit show <the_audit_uuid>" and pastebin me the output please09:01
alexchadinvincentfrancoise: ping09:01
vincentfrancoisealexchadin: hello09:01
alexchadinvincentfrancoise: how are you?:)09:01
vincentfrancoisealexchadin: good :) you?09:02
alexchadinfine! I wanted to ask you about OVO, I'm reviewing it09:02
vincentfrancoisealexchadin: oh good!09:03
vincentfrancoisealexchadin: what is it?09:03
alexchadinvincentfrancoise: as I see, ovo introduces remote objects that are serializing and sending via RPC, right?09:04
vincentfrancoisealexchadin: it's only one aspect of it09:04
alexchadinvincentfrancoise: and it takes a lot of object handling to itself09:04
vincentfrancoisealexchadin: the way I did it doesn't introduce the functionality although everything is set up to activate it in a later BP if we so desire09:05
*** yuanying has joined #openstack-watcher09:05
vincentfrancoisealexchadin: basically, we already defined all the remotable functionalities but I didn't activate their actual remote execution09:05
alexchadincan you describe me the use case of using remote objects? when do we need it?09:06
vincentfrancoisealexchadin: we would first have to decide where the execution would take place and that would probably introduce a new watcher-conductor service or something like this09:06
vincentfrancoisewell, http://cloudystuffhappens.blogspot.fr/2013/04/understanding-nova-conductor-in.html explains it quite well in the case of Nova09:07
*** yuanying_ has quit IRC09:08
alexchadinso, watcher-conductor would manage all the things that are related to the objects and api, applier, d-engine would just call the watcher-conductor to get some objects?09:09
vincentfrancoisealexchadin: yes pretty much09:10
vincentfrancoisealexchadin: but this adds complexity so it's not really needed for now09:10
alexchadin+109:11
vincentfrancoisethat's why I was only interested in implementing the versioning part in order to then implement versioned notifications09:11

alexchadinvincentfrancoise: your OVO patch looks good to me10:17
alexchadinvincentfrancoise: I've not tested it yet, since I started to work on doc for my strategy10:17
vincentfrancoisealexchadin: ah that sounds very good to my ears :)10:17
vincentfrancoisealexchadin: you can look at the tempest test results10:18
vincentfrancoisealexchadin: they are all passing with basic_consolidation10:18
alexchadinvincentfrancoise: cool!10:18
vincentfrancoisealexchadin: but dtardivel is probably going to test it as well I think10:19

digasballe_: acabot : Actually I know about DC license for HyperV, we can save a lot if we make strategy like this15:01
sballe_ok cool15:02
acabotdiga : so how does the HyperV licence works ?15:03
sballe_we just need to make sure thta we have a good use case. I know that when we looked at it in the past it wasn't giving us any saving unless we did it for initial placmenet15:03
digaacabot: but I didnt get travel support from my org, so I am not able to attend summit this time but you should discuss about this,15:03
acabotdo you pay less to MS if you host your windows VM on HyperV ?15:03
digaacabot:If we take DataCenter license in Hyperv, We can place as many VM(Windows) on HyperV15:04
digayes15:04
digaThis is where this idea came into picture, & one more thing, I did observe, if we privision Windows VM on HyperV, performance is far better than others15:05
sballe_what I am trying ot figure out is why have watcher do it and not do it on initial placement? are oyu talking about moving VMs between hosts thta already have hyperV VMs?15:05
digaI am talking about building a strategy around Windows VM to move to HyperV based host to save the licensing cost15:06
digaand then those VMs to HyperV based hosts which has DataCenter license15:07
sballe_oh so it is moving HyperV VM instead of KVM VMs?15:07
digaI talked this with my DC admin, He is actually faced this a lot15:07
digano, KVM/ESXi Windows VMs to HyperV15:08
sballe_i am okay with it. can you point me to the spec and I will review to make sure I understand the use case15:08
digaokay15:09
digaI have submitted the spec yet, but https://blueprints.launchpad.net/nova/+spec/license-cost-aware-vm-placement15:09
sballe_I will need to review the spec to make sure I understand how this would work. please describe the moving of a VM from one hypervisor to another'15:10
digaI have submitted for nova, will re-submit to Watcher & submit the spec15:10
*** alexchadin has joined #openstack-watcher15:10
digasure, I will cover that all the spec15:10
