In this post, we’ll walk through the process of getting virtual machines on two different hosts to communicate over an overlay network created using the support for VXLAN in Open vSwitch (or OVS).
The test environment
For this post, I’ll be working with two systems:
node0.ovs.virtat address 192.168.122.107node1.ovs.virtat address 192.168.122.174
These hosts are running CentOS 8, although once we get past the package installs the instructions will be similar for other distributions.
