15:34:17 sean-k-mooney bauzas: the hypervisror did nto need modifcation to work with vgpus with sriov
15:34:51 bauzas sean-k-mooney: not sure I get your point :)
15:35:11 sean-k-mooney my point is that libvirt works with amd vgpus also
15:35:27 sean-k-mooney you just to a pci passthough of the sriov vf
15:35:47 bauzas ah okay, and amd driver uses SR-IOV for that?
15:35:57 bauzas the AMD driver isn't using mdevs ?
15:36:05 sean-k-mooney yes they do the virtualisation in hardware
15:36:09 bauzas I see
15:36:11 sean-k-mooney they do not use mdevs
15:36:11 bauzas so, the thing is
15:36:20 bauzas I see baby steps here
15:36:38 bauzas step 1/ make sure we have something workable without adding more tech deby
15:37:07 bauzas step 2/ work on the generic thingy from efried and "do the work" (c)
15:37:37 bauzas step 3/ migrate how we track PCI devices from the old world to the new world
15:38:02 fried_rice ++
15:38:12 bauzas hah, Friday!
15:38:28 bauzas holy shit, I said many times I need a ZNC bot for me
15:38:40 mriedem andreykurilin: http://forumtopics.openstack.org/cfp/details/55
15:38:43 mriedem superdan: melwitt: ^
15:39:23 melwitt cool
15:40:27 sean-k-mooney bauwser: makes sense, my concern is coming for interop side in that i would hope at the api level we will not need to expose if it is an mdev or sriov based vgpu
15:40:51 bauwser sean-k-mooney: that's where I'm pretty firm in my mind
15:41:02 bauwser sean-k-mooney: outside the virt driver, we shouldn't leak out the details
15:41:23 sean-k-mooney bauwser: we may need to expose a vender in some form for guest driver reasons but other then that how we virtualise should be internal to nova
15:41:26 bauwser the virt driver will just report inventories
15:41:46 bauwser how those inventories will be populated will be different based on the driver
15:41:59 bauwser but that will be consistent
15:42:17 openstackgerrit Eric Fried proposed openstack/nova master: WIP: Use ksa adapter for cinder client https://review.openstack.org/508345
15:42:41 sean-k-mooney sure and i think we can use traits on the provider to hanel the "i only have a nvida driver in my vm image" problem
15:42:44 fried_rice mordred ^ would you mind checking that I did my version discovery sanely here?
15:43:03 bauwser so that a flavor asking for an amount of 2 of the VGPU resource class and a trait of 'K800' will get 2 K800 vGPUs
15:43:21 bauwser that's where the API is
15:43:46 bauwser actually a good call for trying to fit the fried_rice's model with vGPUs
15:44:19 sean-k-mooney bauwser: perhaps yes or as image metadata where i say i can support x,y,z and the and flavor say i want y and we compare to make sure its compatible
15:45:10 bauwser sean-k-mooney: mmm
15:45:26 bauwser sean-k-mooney: I wonder if that wouldn't be just a filter for the image metadata
15:45:47 bauwser like, I can find all the hosts that can support y (if y is asked by the flavor)
15:45:48 sean-k-mooney im thinking we can add traits to the image metadata
15:45:52 bauwser that is a placement thing
15:46:14 bauwser well
15:46:25 bauwser honestly that's a thought
15:47:22 mordred fried_rice: looks good on quick glance - but I haven't ooked deeply yet
15:47:37 fried_rice mordred Cool, thanks.
15:48:22 bauwser well, I need to call it a day, actually
15:48:48 mriedem fried_rice: let's let mordred deal with the infra fire that's raging
15:48:52 mriedem :)
15:49:19 fried_rice mriedem mordred Sorry, didn't smell the smoke.
15:49:27 mriedem #openstack-infra
15:49:42 sean-k-mooney leakypipes: am qq. is there a way we can retrive the compute node resocue provide by the hostid? and if not would you be against adding one. it could just be a trait
15:50:33 leakypipes sean-k-mooney: each resource provider has a name attribute.
15:50:41 leakypipes sean-k-mooney: that is set to hypervisor_hostname value
15:50:49 leakypipes sean-k-mooney: so yeah, you can already do that.
15:50:55 leakypipes sean-k-mooney: and that name is unique BTW
15:51:24 sean-k-mooney leakypipes: yes i know we require that all hostnames be unique in the openstack cloud
15:51:47 sean-k-mooney leakypipes: the issue is the get resouce provider api to day i think need you to pass the uuid
15:51:50 mriedem sean-k-mooney: you can find the compute node by hostname, and from the compute node uuid look up the RP
15:51:53 mriedem that's what our functional tests do
15:51:58 sean-k-mooney i dont know if we have a rest api call to get it by name
15:52:06 leakypipes sean-k-mooney: no, I mean when resource providers are added by the compute node, the resource provider's name attribute is set to the hypervisor_hostname
15:52:32 sean-k-mooney fried_rice: cool if GET /resource_providers?name={hostname} works that perferct
15:52:34 leakypipes sean-k-mooney: GET /resource_providers?name=$hypervisor_hostname
15:52:43 leakypipes sean-k-mooney: sorry, yeah, fried_rice beat me to it.
15:52:59 fried_rice Yeah, to be technically correct, in case $hypervisor_hostname isn't the same as `hostname`
15:52:59 leakypipes he's a wily coyote, that fried_rice
15:53:16 leakypipes fried_rice: which is the case for Ironic nodes :)
15:53:27 fried_rice right
15:53:39 sean-k-mooney the reason i was asking is for the neutron placement work. when nested provider are added we will need to find the computenode provider for the current host hence question
15:54:17 fried_rice So as long as you know how virt is reporting the hypervisor hostname, you're golden.
15:54:54 sean-k-mooney in neutron i belive we have the host id in a config that must be set to match the one used by nova
15:55:23 leakypipes right
15:55:32 fried_rice # Hostname to be used by the Neutron server, agents and services running on
15:55:32 fried_rice # this machine. All the agents and services running on this machine must use
15:55:32 fried_rice # the same host value. (unknown value)
15:55:32 fried_rice #host = example.domain
15:55:35 fried_rice in neutron.conf ?
15:55:39 leakypipes device_id == hostname, right?
15:55:42 leakypipes sean-k-mooney: ^\
15:55:59 sean-k-mooney device_id?
15:56:41 leakypipes sean-k-mooney: in neutron port response...
15:57:35 leakypipes sean-k-mooney: never mind.
15:57:36 sean-k-mooney oh binding:host_id is
15:57:40 mriedem superdan: http://forumtopics.openstack.org/cfp/details/60
15:57:45 mriedem melwitt: tssurya: ^
15:59:06 superdan mriedem: hmm, did the gate just get dumped?
15:59:16 mriedem idk
15:59:18 sean-k-mooney binding:host_id is set by nova when the port is bound by the compute node
15:59:54 sean-k-mooney leakypipes: but thanks that answers my question ill let rodolfo know
16:00:06 sean-k-mooney and thank fried_rice too
16:00:07 melwitt I thought I saw something in #openstack-infra that said they were gonna stop zuul v3
16:00:08 superdan s'empty
16:00:27 melwitt but I wasn't sure if I read it right
16:00:35 fried_rice I just got a weird merge conflict
16:00:45 superdan well, I had to fix the unit test patch anyway, so I'll push up some fresh in a minute
16:02:54 openstackgerrit Dan Smith proposed openstack/nova master: Move cell0 marker test to Cellsv1DeprecatedTestMixIn https://review.openstack.org/508314
16:02:55 openstackgerrit Dan Smith proposed openstack/nova master: Use improved instance_list module in compute API https://review.openstack.org/505418

16:02:56 openstackgerrit Dan Smith proposed openstack/nova master: Fix minor input items from previous patches https://review.openstack.org/506416
16:03:38 superdan mriedem: did you want me to do something with those session proposals or just headupping me?
16:03:45 mriedem just fyi
16:03:50 superdan ack
