please provide your sight .
I am following openstack icehouse ubuntu installation guide .
I am able to launch install and be able to console in as well .
no IP address in the vm .
used udhcpc -T 1 -A 1 to request ip address from dhcp server .
dhcp server is running on network node .
using traffic mirroring and I see traffic going out br-int patch-tun
interface .
when I try to mirror traffic on br-tun patch-int , I don't see any traffic
coming in .
and also no traffic going out compute node physical interface .
detail here with first section to mirror patch-tun , next is patch-int ,
eth2 .
any idea ? thanks !
section 1 , able to capture patch-tun traffic .
