SR-IOV Networking and OVS - InterVM isn't working

Hi there,

I hope all of you are fine.

I have problem trying to communicate two VMs in the same hypervisor.
VM1 with PCI-Passthrough/SR-IOV and VM2 with VIRTIO/OVS bridge.

Hypervisor have 2 different NIC, 1 NIC (XL710 4x10G) for SR-IOV and other one used for Open-vSwitch. Trying to ping same subnet, on the same VLAN. I get unreachable, I don't see MACs on FDB, ping to other VMs hosted on other hypervisors are working from VM1.

Maybe something related with VEB and VEPA?

Kindly,

Pau
