I have multiple netvms, the MTUs on these need to be set to a specific value to work. Currently I have the following in /rw/config/rc.local :
for I in eth0 eth1 do ip link set mtu 1280 dev $I done
This works if the appvm has the netvm set on boot. However if I change the netvm, a new interface is created in the new netvm which has the default MTU which doesn’t work.
How might I have the MTU set correctly automatically?
