[ovs-discuss] vSwitch simple config - no ping between same br ports

["José Tomás"@Home]

So far I search I always do find
"|master ovs-system state UP|"

at ip addr show where I get
"master ovs-system state DOWN"

help needed to understand why this...

By the way I'm working with fresh installs for Ubuntu 14.04 and 16.04, 
same issue... :(
