Re: [Rdo-list] Neutron Problems

Hi Everyone, I am having problems with my neutron setup and hopefully with your help I can get it figured out. I have a 4 node blade setup with two nics each, all of them running CentOS 6.6. One host is foreman, the other three are for openstack. Since foreman is managing the blades, they have their IP addresses assigned via DHCP to eth0. After the install I noticed that the eth0 device was not attaching to the br-ex device. After lots of work, I was able to get that connected using these configs: ifcfg-br-ex: DEVICE="eth0" #BOOTPROTO="dhcp" BOOTPROTO="none" DEVICETYPE=ovs TYPE=OVSPort OVS_BRIDGE=br-ex #DHCP_HOSTNAME="openstack-1.quicksand.bitc.morphotrust.com" #HOSTNAME="openstack-1.quicksand.bitc.morphotrust.com" HWADDR="E4:1F:13:78:D8:90" #IPV6INIT="yes" MTU="1500" #NM_CONTROLLED="yes" NM_CONTROLLED="no" ONBOOT="yes" #TYPE="Ethernet" UUID="ebd620ad-7e48-4a08-9875-c596b4c4648c" VLAN=yes ifcfg-eth0: DEVICE="eth0" #BOOTPROTO="dhcp" BOOTPROTO="none" DEVICETYPE=ovs TYPE=OVSPort OVS_BRIDGE=br-ex #DHCP_HOSTNAME="openstack-1.quicksand.bitc.morphotrust.com" #HOSTNAME="openstack-1.quicksand.bitc.morphotrust.com" HWADDR="E4:1F:13:78:D8:90" #IPV6INIT="yes" MTU="1500" #NM_CONTROLLED="yes" NM_CONTROLLED="no" ONBOOT="yes" #TYPE="Ethernet" UUID="ebd620ad-7e48-4a08-9875-c596b4c4648c" VLAN=yes I can see eth0 attached to the br-ex, along with the external router port in ovs-vsctl show: Bridge br-ex Port br-ex Interface br-ex type: internal Port "qg-161de698-16" Interface "qg-161de698-16" type: internal Port "eth0" Interface "eth0" Now my problem, I can not get the guest VM to talk out. It can ping to the router port IP (10.30.1.10) but nothing past it. And from my network I can ping to the gateway of that network (10.30.1.1). What else should I check? I feel this is a problem with openvswitch, but I just dont know what to look at. Thanks for any help you can offer. --Brian
