I have a OpenStack kilo setup with a controller and a compute node(network-compute + network-network).

After i created an VM instance and got IP 10.0.0.100 from dnsmasq, i want to ping the instance from the br100(100.0.0.11), i get the error message “ping: sendmsg: Operation not permitted”.

for example: 1)instance ping br100: OK 2)br100 ping instance: “ping: sendmsg: Operation not permitted”

Then I configured “nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0”, but still I not able to ping the Vm instance.

I am confused with this problem a few days. Thanks !
