Hi Jesse, I apologise I did not configure correctly the vswitch on the Ubuntu machine running 1.2. The behaviour seems anyway confirmed in 1.0.99, but I suspect that's unsupported now.
Anyway, is the behaviour when the interface name exceeds the 16 character limit documented? Ovs-vsctl did not raise any error message.
