Hey everyone, We are seeing some strange behavior with our X710 NIC.
SRIOV is enabled, VF are created. We are able to pass the VF to the guest VM. But inside the guest VM, it complains as being unable to talk to the PF. In this example, I gave it two VF on two separate cards. On each X710, its the second 10G interface and in both cases, it's unable to talk to the PF. We have this behavior across 15 different computes all using X710 with a few different firmwares.
