In the controlled test, I set the MTU down to 1360, so the vxlan overhead would still fit under 1500, which is what that lan segment supports. I am assuming my options are either to support larger/jumbo frames or set the hosts lower than 1500. Is there any way to do this on the OVS side?

If it is awfully low, it is likely that your [ outer MTU < (inner MTU + vxlan header)]. You can reduce your inner MTU and see the difference.

However, the VXLAN performance has been poor. I am trying to verify the VM environment. Any recommendations from a performance tuning perspective? Is it possible to get good performance with VXLAN in virtual hardware, or would I be better going with a different tunnel type.
