The Geneve encapsulation protocol uses UDP port 6081. You must allow this port access in the firewall on the KVM host.
Search for the line exclude.
Add the line "kernel* redhat-release*" to configure yum to avoid any unsupported RHEL upgrades.
The supported RHEL version is 7.3.
Install KVM and bridge utilities.
Check the hardware virtualization capability.
cat /proc/cpuinfo | egrep "vmx|svm"
The output should contain vmx.
Verify that the KVM module is installed.
For KVM to be used as a host for NSX Manager or NSX Controller, prepare the bridge network.
In the following example, the first Ethernet interface (eth0 or ens32) is used for connectivity to the Linux machine itself. Depending on your deployment environment, this interface can use DHCP or static IP settings.
Interface names might vary in different environments.
For KVM to be used as a transport node, prepare the network bridge.
Configure one more interface than in the previous step.
Interface names may vary in different environments.
For Ubuntu, all network configurations must be specified in /etc/network/interfaces. Do not create individual network configuration files such as /etc/network/ifcfg-eth1, which can lead to transport node creation failure.
To make the networking changes take effect, restart networking service systemctl restart network or reboot the Linux server.
