With SRIOV instances, the VM has a virtual network card VF, that goes straight physically to the ToR switch on an specific VLAN. This will not work with OVN because the gateway nodes need to be reached on the L3 router MAC address, and the MAC address flaps on current implementation.
We have Anil's patches that partially address VLAN support, but SRIOV+VLAN will be not covered because of the detail explained on previous comment
https://patchwork.ozlabs.org/bundle/mangelajo/l3-vlan/
According to our records, this should be resolved by openvswitch-2.9.0-97.el7fdp. This build is available now.
The target release is osp13z6 moving to modify until we get a puddle.
