What did you actually do/configure when you tried jumbo frames?

I'm not sure.. I have never really tried jumbo frames with Xen..

I assume first you need to configure your ethX (pethX) devices to use 9000
bytes mtu.. and then your bridge devices to use 9000 mtu too.

After that you need to configure your ethX devices in domU to use 9000 mtu.

Is that enough? Has someone tried this?
