Testing the Interconnection Between VMs in Different AZs

Perform the following operations on the controller node.

1. Source the admin credentials to gain access to admin-only CLI commands.

   1	source /etc/keystone/admin-openrc

2. Create an instance flavor.

   openstack flavor create ${flavor_name} --ram $RAM_MB --vcpus $CPU --disk $DISK_GB --public

   Figure 1 flavor creat
   
3. Create an x86 VM in the x86 compute AZ (select the self-service x86 network).

   1	openstack server create --flavor 4u8g40gb --image CentOS-7.6-x86_64 --nic net-id=test_selfservice_x86 --availability-zone az-x86 x86-self-service-instance

4. Create an Arm VM in the Arm compute AZ (select the self-service Arm network).

   1	openstack server create --flavor 4u8g40gb --image CentOS-7.6-aarch64 --nic net-id=test_selfservice_arm --availability-zone az-arm arm-self-service-instance

5. Test the network connectivity between two VMs in different AZs.
   1. Query the IP addresses of the created VMs.

      1	openstack server list

      

   2. Query the IP address and port number of the VNC console.

      1	nova get-vnc-console x86-self-service-instance novnc

      

   3. Log in to the VM using a browser and ping the IP address of another VM.

      1	ping <arm-self-service-instance ip>
