3. Disable Selinux.
4. In the
/etc/selinux/config
file on the Network, Compute1, and
Compute2 nodes, change
SELINUX=enforcing
to
SELINUX=permissive
.
5. Disable the firewall by issuing the following command:
# systemctl disable firewalld && systemctl stop firewalld
6. Make sure the correct version of the NIC drivers are loaded on the
Compute1 and Compute2 nodes:
 bnx2x (3400 and 8400 Series Adapters)
 qede/qed (45000 Series Adapters)
You can use the Red Hat 7 inbox driver to check the version.
7. Set the MTU size to 1600 for the VXLAN header.
This size avoids fragmentation, which can impact throughput.
VXLAN Configurations
For VXLAN configuration using OVS and the ML2 plug-in, make the configuration
changes described in the following sections for all nodes (Controller, Network,
Compute1, and Compute2).
Controller Node Configuration
To configure the Controller node:
1. In the Controller node, edit the
/etc/neutron/plugins/ml2/ml2_conf.ini
file as follows:
[ml2]
tenant_network_types = flat, vxlan
type_drivers = vxlan
mechanism_drivers = openvswitch.
[ml2_type_vxlan]
