Description Miguel Angel Ajo 2018-08-07 13:17:52 UTC
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.

Comment 1 Miguel Angel Ajo 2018-08-07 13:20:07 UTC
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

Comment 2 Miguel Angel Ajo 2018-08-07 13:22:22 UTC

Comment 8 Lon Hohberger 2019-03-21 10:35:57 UTC
According to our records, this should be resolved by openvswitch-2.9.0-97.el7fdp.  This build is available now.

Comment 10 Eran Kuris 2019-03-28 07:00:38 UTC
The target release is osp13z6 moving to modify until we get a puddle.
