Comment 4 zenghui.shi 2021-06-21 12:19:04 UTC

Rafal, could you help collect the following net-attach-def info?

oc get net-attach-def sriov2-25-1311 -n default -o yaml
oc get net-attach-def sriov1-25-1310 -n default -o yaml

Wanted to check if the generated net-attach-df contain the right ipam field.

Comment 6 zenghui.shi 2021-06-23 02:05:47 UTC

I don't see any issue with the generated net-attach-def.

How did you check the ip address for sriov interfaces?
What deviceType is used when creating SriovNetworkNodePolicy? Is it netdevice or vfio-pci ?

Comment 9 zenghui.shi 2021-06-23 09:14:02 UTC

ok, from comment #8, SriovNetworkNodePolicy CRs are using vfio-pci deviceType, in which mode VF devices are no longer observed as kernel interfaces, which means IP address cannot be configured to the VF devices. This is expected when vf is used for dpdk application (vfio-pci).  
IP address can be configured to VF device when SriovNetowrkNodePolicy is using netdevice deviceType.

Comment 10 Rafal Szmigiel 2021-06-23 12:46:40 UTC

You're absolutely right - once I switched it to netdevice the IPs are being assigned/visible in the outputs.
Many thanks for your help!

Best Regards,

Rafal
