esbergluThe error is coming from line 303 in jenkins_jobs/builder.py13:50

thorstyeah...but is that just the refactor?13:52
thorstdid we change anything in our YAML?13:52
adreznecThat... doesn't seem right? That commit is from last year...13:52
adreznecUnless it took this long to get into a verison13:53
adreznec*version13:53
esbergluBut the actual error isn’t coming from the parser it’s from trying to load self.plugins_list13:53
esbergluYeah it merged in recently13:54

*** burgerk has joined #openstack-powervm13:57
adreznecesberglu: If you replace JJB master install with the latest release (1.6.1.) does it fix things?13:58
esbergluI think that that line above should be accessing self._plugins_list not self.plugins_list13:58
esbergluthorst: adreznec: Yeah changing that passed the tox14:03
adreznecOk, so definitely a conflict with something merged since June 9th then14:04

efriedthorst, svenkat and I would like to discuss SR-IOV enablement in nova15:55
efriedWould like to explore the possibility of getting a change in core nova to enable "virtual" SR-IOV attachment.15:56
efriedThere was another hypervisor that needed to do something similar.  They actually deferred their blueprint to ocata - possible partially for that reason.15:57
svenkatok…15:58
efriedWould we need an actual blueprint in nova to make that happen at this point, or could we slide it in as a "bug"?15:58
svenkatefried : do you know exactly what needs to be done? what chnages to pci white list15:58
svenkatso when you create a vnic type direct port and boot a vm with it, create_pci_requests_for_sriov_ports in nova/network/neutronv2/api.py adds pci request to network...15:59
efriedNot exactly.  You will have to create an entry that doesn't trigger any of the libvirt-centric device special file-based validation code.16:00
efriedMeans you need to avoid setting certain fields, but I don't remember exactly which ones those are.  It wasn't hard to figure out by poking at the code, though.16:00
svenkatok..16:00
efriedAnd the other bits should be able to be dummied out.16:00
svenkatok…16:00
efriedI think the code will simply require there to be *something* there.  I'm not sure it's going to matter what it is.16:01
svenkatok…16:01
svenkati will look at compute init code that reads pci whitelist again.16:01
efriedBut if we could propose a simple change to nova that would allow the whitelist to be empty without erroring, that would be best.16:01
svenkatsure.16:02
thorstwe could say that, but we need to find another hypervisor that can benefit from that16:02
thorstcause of obvious reasons16:02
efriedYeah, I would have to find that other blueprint.16:02
efriedWhat's another platform that doesn't have the hypervisor owning all the hardware?16:02
*** k0da has quit IRC16:03
thorstwell, isn't it more, what's another platform that doesn't have linux as the hypervisor/16:03
efriedsure, that would work.16:03
thorstVMware & hyper-v16:03
efriedI read an actual blueprint from an actual hypervisor that wanted to implement SR-IOV something-or-other, but they had to punt to ocata.16:03
efriedIt may have been VMWare.16:03
efriedNot sure how I'm going to find that sucker again...16:03
thorstgaryk may have it?16:04
thorstI think he's vmware16:04
adreznecYeah16:06
adreznecIt was vmware16:06
adreznecefried: I think it was https://review.openstack.org/#/c/317126/16:07
efriedadreznec, yup, that was the one, thanks.16:08
efriedmaybe16:09
adreznecIt was the one I remembered16:09
adreznecThere may be more16:09

thorstI'd give you an e-high five20:07
thorstI have to try it out...one of the benefits of having a system failure is seeing the reboot scenarios20:08

thorstI can also have madhavi take a peak if you've got another thing to chase...it is for the OVS / SDN stuff20:17
efriedthorst, you need to add new_vif=False to the new plug call, yes?20:22
thorstyeah, I missed a couple things20:22
efried...and finish the comment on line 124?20:22
efriedthorst, so you need me for what, UT?20:24

efriedoic20:27
efriedthorst, so line 107 needs new_vif=new_vif ?20:28
thorstefried: yep20:28
thorstjust saw that20:29

efriedWell, once you have the code, you can huck it over the fence and I can UT it.20:29

efriedthorst, svenkat https://review.openstack.org/#/c/343423/7/networking_powervm/plugins/ibm/agent/powervm/sriov_agent.py@6621:03
efriedGot a moment to discuss?21:03
svenkatefried sure…21:04
thorstname to name21:04
efriedsvenkat, could you make use of the pport loc codes?  Presumably these mappings are accessible to the plug method?21:05
svenkatbut this data has to  go to mechaism driver… and there they have to be matched with neutron network object data.. ( one ofthemis physcal network. thats why i am puling port labels and includeing them in bridge mapping)21:06
svenkatneutron network object does not have location codes…21:06
*** seroyer has quit IRC21:06
efriedThe keys would still be the net names.21:07
svenkatok. i can do that21:07
efriedThe values would be the physloc codes, as a list.21:07
thorstwhy not just 'default:default'21:07
svenkatbut what is the prupose of location code in bridge mapping21:07
efriedThat would save you the entire chunk from line 500-511 in https://review.openstack.org/#/c/343419/5/nova_powervm/virt/powervm/vif.py21:07
efried...assuming you could get at that data from plug.21:08
svenkatoh ok…21:08
efriedthorst ^^21:08
svenkati can see if mech driver can push that data into vif21:08
svenkatlike vlan id21:08
svenkatunder vif details, i can put whatever21:08
thorstyep21:08
thorstdig it...however, remember21:08
svenkatso i thiik it is possible to put loc codes in vif...21:09
thorstthe mechanism driver runs on the neutron server.21:09
svenkatyes..21:09
thorstnot necessarily on the compute node21:09
thorstso we'd have to have the mechanism driver get it from the agent21:09
thorstwhich I think can be done21:09
svenkatyes. bridge mapings flow from agent to server and mech driver to vif is between neutron server to nova compute…21:09
efriedPretty sure that's how it *is* done.21:09
efriedyeah, what he said.21:09
svenkatyes. just like we push vlan id to vif from mech driver21:09
svenkatgood point efried. i wilil give it a shot21:10
efriedCool beans.21:10
thorstseems like that gets rid of all the calls in the vif to neutron21:10
svenkati thought we removed all that already… no more neutron calls in vif21:10
efriedwhat, vif.get_physical_network()?21:10
svenkatthat is also flowing from mech driver to vif21:11
svenkatto get physical network, vif need not have to go to neutron21:11
svenkatwith loc code in vif suggestion, we will save using pypowervm to get port labels. instead wewill get them from vif directly21:12
svenkatmore on get_physical_network it i smade possible by the way port is created21:12
svenkatneutron port-create --debug --vnic-type direct e23ef566-2942-47fc-aaf6-35b905904767 -- --binding:profile type=dict physical_network=default21:12
svenkatbinding profile physical network dictionary item in port makes mech driver to push it to vif21:12
svenkatif you create a port without binding profile, then it does not work21:13
