I just comment some of floodlight codes and VMs can ping the gateway.
But I do not know why the gateway port and link is down, it is up in
namespace view:
root@controller
:/usr/src/eclipse# ip netns exec
qrouter-7bde1209-e8ed-4ae6-a627-efaa148c743c ip link
14: qr-8af2e01f-bb: BROADCAST,MULTICAST,UP,LOWER_UP mtu 1500 qdisc

hi
I use quantum grizzly with namespace and floodlight, but VMs can not ping
its gateway. It seems that floodlight ignore devices whose status
is PORT_DOWN or LINK_DOWN, somehow the subnetwork gateway is
really PORT_DOWN and LINK_DOWN.. is it normal?or how can I change its
status to normal?
