Hi list, I've been trying to set up an external network for a few days and this driving me crazy. I have a topology close to the one described in the ubuntu 14.04 documentation for icehouse (using networking not legacy) My setup is completely running under vitrualbox as this is just a POC at the moment, I have checked that my neutron node is allowed to put its network interface in promiscuous mode which seem to be the case but none of the interface on my neutron node actualy get put in promisc mode. My external network is 192.168.199.0/24 (I don't have a public network available) and I have an external router providing gateway on 192.168.199.1. my pool is defined from .101 to .150 However I cannot ping .101 from the external router. I have tried adding an extra network interface to the neutron node plugged in on the same network as the external router (.45) and from that one I can ping the router just fine. My questions are : Is it normal that none of the neutron node interface are in promisc mode ? oot at os-network:~# netstat -i Kernel Interface table Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg br-ex 1500 0 11 0 0 0 8 0 0 0 BRU br-int 1500 0 22 0 0 0 8 0 0 0 BRU br-tun 1500 0 0 0 0 0 8 0 0 0 BRU eth0 1500 0 12199 0 0 0 3959 0 0 0 BMRU eth1 1500 0 1338 0 0 0 1940 0 0 0 BMRU eth2 1500 0 2 0 0 0 18 0 0 0 BMRU eth3 1500 0 15 0 0 0 17 0 0 0 BMRU eth4 1500 0 9 0 0 0 14 0 0 0 BMRU lo 65536 0 18 0 0 0 18 0 0 0 LRU Do you have any poitner or direction I can follow to troubleshoot this ?
