Overview
This wiki page describes how to tune Mellanox OpenStack on Ubuntu 12.04 servers
Prerequisites
- A running OpenStack environment installed with the ML2 plugin on top of OVS.
- All nodes equipped with Mellanox ConnectX®-3 Network Adapter (http://www.mellanox.com/page/products_dyn?product_family=119)
- Mellanox OFED 2.2 or greater installed on all nodes. Please refer to Mellanox website for the latest OFED: http://www.mellanox.com/page/products_dyn?product_family=26&mtag=linux_sw_drivers
- SR-IOV enabled on all compute nodes. For more information, please refer to Mellanox Community click here.
- The software package iproute2 - (http://www.linuxfoundation.org/collaborate/workgroups/networking/iproute2 ) installed on all Compute nodes
- VLANs configured on the ports in the switch.
Ethernet Network
Controller Node
In /etc/nova/nova.conf ensure you have the following line:
security_group_api=nova
If the value is changed, restart the Nova services:
# for i in $(initctl list | grep '^nova' | awk '{print $1}'); do service $i restart; done
Neutron Server Node
NOTE: The Neutron Server can sometimes be part of the Controller node.
To configure Neutron-Server node:
1. Edit /etc/neutron/neutron.conf, and make sure Neutron is using ML2 plugin:
[DEFAULT] core_plugin = neutron.plugins.ml2.plugin.Ml2Plugin
2. Modify the ML2 configuration file (/etc/neutron/plugins/ml2/ml2_conf.ini) as follows:
[ml2] type_drivers = vlan,flat tenant_network_types = vlan mechanism_drivers = openvswitch,mlnx [ml2_type_vlan] network_vlan_ranges=<physical_network>:<min_vlan>:<max_vlan> //(i.e. default:2:10) [securitygroup] enable_security_group = True [eswitch] vnic_type = hostdev apply_profile_patch = True
3. Install the required Deb for the Mellanox Neutron plugin (from Ubuntu’s repository):
apt-get install neutron-plugin-mlnx-agent
4. Edit /etc/neutron/plugins/mlnx/mlnx_conf.ini to match your environment:
[mlnx] network_vlan_ranges = <physical_network>:<min_vlan:<max_vlan> //(i.e. default:2:10) tenant_network_type = vlan [eswitch] physical_interface_mappings = <physical_network>:<eth interface> //(i.e. default:eth0) vnic_type = hostdev [agent] support_old_agents = True
5. Restart neutron-server:
/etc/init.d/neutron-server start
Compute Nodes
To configure the Compute node:
1. Download mlnxvif and eSwitch Daemon (eSwitchd) from the following link:
http://www.mellanox.com/downloads/solutions/openstack/icehouse/debian/
2. Install the Mellanox plugin services mlnxvif and eSwitchd:
dpkg –i python-mlnxvif_2014.1.1-1_all.deb dpkg –i python-eswitchd_0.10-1_all.deb
3. Edit /etc/eswitchd/eswitchd.conf as follows:
[DAEMON] fabrics=<physical_network>:<eth-interface> //(i.e. default:eth0)
4. Edit /etc/nova/nova.conf as follows:
[DEFAULT] compute_driver = libvirt.LibvirtDriver libvirt_vif_driver = mlnxvif.vif.MlxEthVIFDriver security_group_api = nova
5. Check if “ebrctl” appears in one of Nova’s rootwrap files:
grep 'ebrctl' /etc/nova/rootwrap.d/*
If “ebrctl” does not appear in one of Nova’s rootwrap files, edit the file /etc/nova/rootwrap.d/compute.filters as follows:
[Filters] ebrctl: CommandFilter, ebrctl, root
6. Install the Neutron Mellanox agent (from Ubuntu repository):
apt-get install neutron-plugin-mlnx-agent
7. Copy /etc/neutron/plugins/mlnx/mlnx_conf.ini from the Neutron Server node to the same path on each Compute node. 8. Restart the following services:
/etc/init.d/nova-compute restart /etc/init.d/eswitchd start /etc/init.d/neutron-plugin-mlnx-agent start
Network Node
1. Install the Neutron Linux bridge plugin, the Neutron DHCP agent and the Neutron L3 agent:
# apt-get install neutron-plugin-linuxbridge-agent neutron-dhcp-agent neutron-l3-agent
2. Copy /etc/neutron/neutron.conf from the Compute node.
3. Change the following configuration of the ini file (/etc/neutron/plugins/linuxbridge/linuxbridge_conf.ini). The "default" in the example is the name of the physical network as configured in /etc/neutron/plugins/mlnx/mlnx_conf.ini .
[linux_bridge] physical_interface_mappings = default:eth2
4. Configure the DHCP agent according to the following guidelines
Update the following file: /etc/neutron/dhcp_agent.ini with:
[DEFAULT] interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
For additional information refer to the OpenStack documentation
5. Configure the L3 agent according to the following guidelines
Update the following file: /etc/neutron/l3_agent.ini with:
[DEFAULT] interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
For additional information refer to the OpenStack documentation
6. Configure the Metadata agent according to the OpenStack documentation
7. Start the Neutron Linux Bridge, DHCP and L3 agents
# restart neutron-plugin-linuxbridge-agent # restart neutron-dhcp-agent # restart neutron-l3-agent # restart neutron-metadata-agent
Troubleshooting
- If you're seeing request timeout errors in the plugin's logs, make sure that the eswitchd service is started and try to increase the request_timeout value in the plugin configuration file.
