Hello eyeryone,
I'm kind of new with OpenStack. Three months ago I managed to deploy OpenStack using Packstack on three nodes. Three VMs with CentOS 7 minimal created using VM Ware ESXI hypervisor: a controller node, a network controller node (Neutron) and a compute node (Nova). Things worked all right there as a test bed for PoC and lunching a few instances. That was OpenStack Newton. Yesterday I followed the very same procedure and I ran into two problems: first problem was related to NTP, and I finally found a workaround for it. However the second problem I couldn't handle it so far and I hope to get some kind recommendations here. The problem is that it seems the traffic does not go off to the External network I create an external network and a Router on a project using Horizon and connect the external network to the gateway of the Router. Everything seems fine, but I can't ping the router's gateway from my own client which are on the same subnet. It seems that External Bridge does not route the traffic outside. I can't ping the router's gateway from Neutron server. With this big problem I can't go further, because instances won't be able to ping outside network, also they won't be reachable from outside. I checked the firewall on my client and even turned it off. Also I checked Neutron server's firewall status using: "systemctl status firewalld" and service seemed dead. Here is my eth0 and External bridge configurations on Neutron server: eth0: DEVICETTYPE=ovs TYPE=OVSPort OVS_BRIDGE=br-ex DEVICE=eth0 NAME=eth0 BOOTPROTO=none ONBOOT=yes External bridge: TYPE=OVSBridge DEVICE=br-ex NAME=br-ex BOOTPROTO=static DEVICETYPE=ovs ONBOOT=yes IPADDR=172.16.10.123 NETMASK=255.255.255.0 GATEWAY=172.16.10.1 DNS1=8.8.8.8 PEERDNS=yes USERCTL=yes Even I lunched three instances using Cirros image and they able to ping each other, also able to ping the gateway of the router, However nothing seems reachable from outside. That's why I think there should be something wrong with External Bridge. Please Help, if you have any alternative config for external bridge and NIC card, or whatever useful to help my limit knowledge... Thank you Rez P.S: Is the NIC card type in VM has anything to do with this problem? I mean when I created the Virtual machines, I chose VMXNET3 as NIC card type, should I try another type, something like E1000, maybe for compatibility?
