Verifying OpenStack Installation on a Single Node

This shows how to access VM instances and perform traffic test after the OpenStack deployment is complete.

1. List the VMs using virsh.

   virsh list --all

   An output example:

    Id   Name                State
   -----------------------------------
    1    instance-00000001   running
    2    instance-00000002   running

2. Access the VMs.

   virsh console <VM instance name>

3. Compare the MAC addresses of the ports on the host and on the VMs.
   Execute the following command on the host to get the MAC address of a port.

   openstack port show <port_name> | grep mac_address

   For example:

   openstack port show port10 | grep mac_address

   An output example:

   | mac_address             | fa:16:3e:e8:6c:42 

   Note: The following command must be executed to enable the openstack commands when a new terminal is opened.

   source keystonerc_admin

   Check the MAC address on each VM. For example:

   ip a

   Note: If the IP address is not assigned, configure manually.

   ip a add <ip>/<netmask> dev eth0

   For example:

   ip a add 192.168.1.10/24 dev eth0

   Two VMs should now be connectable via ping.

4. Test with traffic between two VMs using iperf3.
   For example:

   # Start iperf3 as a server on one VM
   iperf3 -s
   
   # Start bandwidth test on another VM
   iperf3 -c 192.168.1.X

   where X is the last field of the iperf3 server IP address.
