Red Hat Training
A Red Hat training course is available for Red Hat OpenStack Platform
18.3. Extend the Tenant Network for the Benchmarking Service
The following procedure is
optional
and required only if the Benchmarking service scenario being run requires a direct access (ssh
) to the guest. When running the NovaServers.boot_server
scenario, extending the tenant network is not required as this is specific scenario does not ssh
into the guests but simple launches the guests.
Perform the following steps on your Controller node, unless otherwise specified.
- If your Red Hat OpenStack Platform deployment does not have any floating point IPs available, extend the Tenant network to the
rally
host. Run the following command to install the OpenStack Networking OpenvSwitch agent package:#
yum install openstack-neutron-openvswitch
- Copy the OpenStack Networking configuration files from the Compute node to the Controller node:
#
scp COMPUTE_NODE_IP:/etc/neutron/* /etc/neutron
- Set an IP address to the interface that would have been associated with the Tenant network had it been part of the OpenStack cluster.
- Edit the
ovs_neutron_plugin.ini
file and change thelocal_ip
to the IP address that resides on the Tenant network:[OVS] vxlan_udp_port=4789 network_vlan_ranges= tunnel_type=vxlan tunnel_id_ranges=1:1000 tenant_network_type=vxlan local_ip=IP_WITHIN_TENANT_NETWORK enable_tunneling=True integration_bridge=br-int tunnel_bridge=br-tu
- Edit the
/etc/neutron/plugin.ini
file and change thelocal_ip
to the IP address that resides on the Tenant network:[OVS] vxlan_udp_port=4789 network_vlan_ranges= tunnel_type=vxlan tunnel_id_ranges=1:1000 tenant_network_type=vxlan local_ip=IP_WITHIN_TENANT_NETWORK enable_tunneling=True integration_bridge=br-int tunnel_bridge=br-tun
- Restart the
neutron-openvswitch-agent
:#
systemctl restart openvswitch
#
systemctl restart neutron-openvswitch-agent
- On the Controller node, verify the agent is properly setup by using the
neutron agent-list
command:#
neutron agent-list
... Output Abbreviated ... ] | 8578499b-0873-47a9-9cae-9884d4abf768 | Open vSwitch agent | Controller_Host | :-) | True | neutron-openvswitch-agent - On the Controller node, create the variables
netid
andhostid
with the following information:#
netid=PRIVATE_NETWORK_ID
#
echo $netid
#
hostid=CONTROLLER_NODE_HOSTNAME
#
echo $hostid
- On the Controller node, create a
neutron
port labelledrally-port
that binds to thehost_id
and creates the port within the network of the associatednetid
.#
neutron port-create --name rally-port --binding:host_id=$hostid $netid
Created a new port: +----------------------- +---------------------------------------------------------------------------------+ | Field | Value | +----------------------- +---------------------------------------------------------------------------------+ | admin_state_up | True | | allowed_address_pairs | | | binding:host_id | VISIONING_HOST | | binding:profile | {} | | binding:vif_details | {"port_filter": true, "ovs_hybrid_plug": true} | | binding:vif_type | ovs | | binding:vnic_type | normal | | device_id | | | device_owner | | | extra_dhcp_opts | | | fixed_ips | {"subnet_id": "5279a66d-a5f5-4639-b664-163c39f26838", "ip_address": "10.1.0.2"} | | id | 0a9e54da-6588-42ce-9011-d637c3387670 | | mac_address | fa:16:3e:44:c3:d9 | | name | rally-port | | network_id | 1cd7ae4f-d057-41bd-8c56-557771bf9f73 | | security_groups | 76fe37c7-debb-46b4-a57a-d7dbb9dfd0ed | | status | DOWN | | tenant_id | 6f98906137a2421da579d4e70714cac6 | +----------------------- +---------------------------------------------------------------------------------+ - Within the Controller node, modify the
rally
virtual machine XML with the following:#
virsh edit rally
... <interface type='bridge'> <mac address='fa:16:3e:1a:3b:f1'/> <source bridge='br-int'/> <virtualport type='openvswitch'> <parameters interfaceid='neutron-port-id'/> </virtualport> <target dev='vnet4'/> <model type='virtio'/> <alias name='net1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x0f' function='0x0'/> </interface> ...Note
Make sure you update theneutron-port-id
with theid
located in the previous step when creating therally-port
. - After the XML file changes have been applied to the
rally
guest, reboot the guest.
