kzaitsev_wsivc_: hm. any ideas how I can pass physnet information to the CNI?08:18
kzaitsev_wsI used to pass it as part of the annotation, but now that I've converted the annotation to {ifname: vif-obj} there's place for it anymore =/08:20
kzaitsev_wsI can probably use a custom DirectVIF...08:20

apuimedoif it works for you and it works for me I'll merge it09:16
*** yedongcan has quit IRC09:18
kzaitsev_wsI'll try to =) Just need to finish with converting sriov to a new spec-version09:18
*** yedongcan has joined #openstack-kuryr09:19
kzaitsev_wseh, seems like I would have to add a custom vif-type or at least vif-port-profile in the end09:21

mchiapperoI'm not sure what's going on10:46
mchiapperobut previously overcloud was working fine10:46
mchiapperoIs there a way I can debug?10:46
ivc_kzaitsev_ws you'll need to create new os-vif VIF type10:58
ivc_and you can add any relevant info you need to it10:59
ivc_kzaitsev_ws check this patch https://github.com/openstack/kuryr-kubernetes/commit/dc65eb1cbd19df8e4627bc734dc99cdba1d7ac6911:03

kzaitsev_wsivc_: yeah. I was just hoping I could re-use os_vif.vif.VIFDirect =)12:10
*** aojea has quit IRC12:15
*** aojea has joined #openstack-kuryr12:16
*** aojea has quit IRC12:20
ivc_kzaitsev_ws btw it might make sense to get in touch with nova/os-vif folks about VIFSRIOV, they most likely planning to add it to os-vif12:21
kzaitsev_wsivc_: I think VIFDirect is exaclty for sriov12:24
kzaitsev_wsit's more like they don't have a physnet field in Network object12:25
ivc_kzaitsev_ws i would not be so sure about that :)12:27

ivc_kzaitsev_ws btw why do you need physnet field?12:41
kzaitsev_wsivc_: because I need to know which PF to use for a VF12:42
ivc_kzaitsev_ws does not the port returned by neutron have the pci address?12:42
kzaitsev_wshow would neutron know in advance which pci address to assign to the port?12:43
*** yamamoto has quit IRC12:43
kzaitsev_wsi.e. which pci device on some compute node would be allocated for the specific port12:44
ivc_kzaitsev_ws so how does it work with nova? who allocates VFs?12:45
*** yamamoto has joined #openstack-kuryr12:50
kzaitsev_wsI believe nova does the heavylifting. you add the `PciPassthroughFilter` to the scheduler and `pci_passthrough_whitelist` on computes. And finally a sriov-agent on computes to let it know which devices map to which physnet12:51
kzaitsev_wshttps://docs.openstack.org/ocata/networking-guide/config-sriov.html here are the docs on how to set things up12:51
ivc_kzaitsev_ws do you have a link to the code in nova that implements it?12:53
ivc_kzaitsev_ws i have some doubts about the correctness of your approach in https://review.openstack.org/#/c/462456/5/kuryr_kubernetes/cni/binding/sriov.py@8412:54
*** yamamoto has quit IRC13:00
kzaitsev_wsivc_: that approach I took from neutron's sriov manager. I'm not sure if I can find exact place in nova/neutron, where device is passed to the vm, though13:02
kzaitsev_wslet me share the manager link13:03
kzaitsev_wsivc_: https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/mech_sriov/agent/eswitch_manager.py13:05
*** salv-orlando has joined #openstack-kuryr13:07
kzaitsev_wsit's hard to pinpoint the exact place in the code, where the device is passed to the VF =( and the mechanism would be different for containers anyway since we only need to pass the VF to Pods network ns13:14
