Hi, I am in the process of setting up a cluster of 4 CentOS 6.4 servers, with Neutron and VLAN. The current goal is to create under the same tenant 3 subnets in different VLANs. Also, I've used the following guides to do this:
http://openstack.redhat.com/Neutron_with_OVS_and_VLANs http://docs.openstack.org/grizzly/openstack-network/admin/content/under_the_hood_openvswitch.html I have tried alternative setups: A. All services (including compute) on one host + 3 additional compute hosts. B. All services (except compute) on one host + 3 additional compute hosts. In case A, the guest VM is by default launched on the same host that runs the rest of the services -- then the VM is reachable. In case B, the VM is started on one of the compute hosts -- and then the guest VMs are not reachable (though running on the compute nodes and viewable through the instance console) e.g.: ip netns exec qrouter-b702c4e9-cb3a-4156-8412-f902363075f2 ping 10.0.103.5 PING 10.0.103.5 (10.0.103.5) 56(84) bytes of data. >From 10.0.103.1 icmp_seq=2 Destination Host Unreachable >From 10.0.103.1 icmp_seq=3 Destination Host Unreachable >From 10.0.103.1 icmp_seq=4 Destination Host Unreachable I've double checked the security group and rules (to allow ssh and icmp). Logs don't show anything interesting. Questions: * Do the compute hosts need any additional services set up (except the quantum-openvswitch-agent and openswitch)? * Could you suggest any troubleshooting tips/techniques? cheers, /Nico
