[ovs-discuss] Can not change MTU of emulated ports (ethxxxx-emu)

[Jamshaid Faisal]

Hello

I need to change MTU of OVS bridge to 9000. And this is only possible if
all ports of OVS are mtu 9000.

I am using XEN (xl toolstack) which is creating  emulated interface in OVS
for each port it create. for example each port is added in ovs as two ports

ethxxxxx
ethxxxxx-emu

i can set the mtu for ethxxxxx but if i try to set mtu > 1500 for emulated
interface ethxxxx-emu, i get the error

SIOCSIFMTU: Invalid argument

So it seems those emulated ports dont support MTU greater then 1500. In
this case how can i switch MTU of bridge to 9000 ?

Thanks for any help you can provide.
