Hi, I managed to deploy a compute node with ovs-dpdk using two NICs. The first for the provisioning network and control plane, the other NIC is used tenant network over ovs-dpdk. I then tried to use only a single nic for provisioning and ovs-dpdk. I used the nic configuration below for the compute nodes running ovs-dpdk but encountered two problems. First the tenant network was working (wasn't able to get DHCP running and even when I manually configured it wasn't able to reach the router) Second the default route on control plane is not set even though it is configured in /etc/sysconfig/network-scripts/route-br-ex Samuel OsNetConfigImpl: type: OS::Heat::StructuredConfig properties: group: os-apply-config config: os_net_config: network_config: - type: ovs_user_bridge name: {get_input: bridge_name} use_dhcp: false dns_servers: {get_param: DnsServers} addresses: - ip_netmask: list_join: - '/' - - {get_param: ControlPlaneIp} - {get_param: ControlPlaneSubnetCidr} routes: - ip_netmask: 169.254.169.254/32 next_hop: {get_param: EC2MetadataIp} - default: true next_hop: {get_param: ControlPlaneDefaultRoute} members: - type: ovs_dpdk_port name: dpdk0 members: - type: interface name: nic1 - type: vlan vlan_id: {get_param: InternalApiNetworkVlanID} addresses: - ip_netmask: {get_param: InternalApiIpSubnet} - type: vlan vlan_id: {get_param: TenantNetworkVlanID} addresses: - ip_netmask: {get_param: TenantIpSubnet} _______________________________________________ users mailing list users(a)lists.rdoproject.org http://lists.rdoproject.org/mailman/listinfo/users To unsubscribe: users-unsubscribe(a)lists.rdoproject.org

I think you have an issue here: members: - type: ovs_dpdk_port name: dpdk0 members: - type: interface name: nic1 It appears that you have the ovs_dpdk_port as a member of the user bridge, but then you have the NIC and the VLANs as members of the ovs_dpdk_port, but the VLANs should be members of the bridge, not the ovs_dpdk_port. But that might not be the case, which is why I would like to see the original unmodifed NIC config. -- Dan Sneddon | Senior Principal OpenStack Engineer dsneddon(a)redhat.com | redhat.com/openstack dsneddon:irc | @dxs:twitter
