Hi, =

When = creating a dpdkvhostuser port in ovs 2.5, when starting vm which = connected to this port, using command “ovs-ofctl show br0”, = it will shows like this:

3(vhost-user-0): = addr:00:00:00:00:00:00

config: = PORT_DOWN

state: = LINK_DOWN

speed: 0 = Mbps now, 0 Mbps max

the config and state are both wrong, is this bug = fixed?

If not fix this bug, when ovs is controlled by sdn = controller like Floodlight, floodlight will check ovs’s port using = only config and state as follows:

public boolean isEnabled() = {

return = (!state.contains(OFPortState.LINK_DOWN) && = !config.contains(OFPortConfig.PORT_DOWN));

}

So, dpdkvhostuser port = will be treated as not enabled and the packet-in message will drop which = will cause the vm connected to dpdkvhostuer port can’t communicate = with other vms;

Thank = you.
