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.
