Creating a VM Network

You can refer to this section to create different types of networks as required.

1. Import environment variables.

   source ~/.admin-openrc

2. Create a network.

   openstack network create $net_name --provider-network-type vxlan --project admin --provider-segment 300

   

   Replace net_name with the name of the created VM network.

3. Create a subnet.

   openstack subnet create $subnet_name --ip-version 4 --project admin --network $net_name --subnet-range $subnet --allocation-pool start=$start_ip,end=$end_ip

   

   Modify the following parameters as required:

   • Replace subnet_name with the name of the created subnet.
   • Replace net_name with the name of the network created in step 2.
   • Replace subnet with the created subnet segment. For example: 192.168.101.0/24.
   • Replace start_ip with the start IP address of the network segment.
   • Replace end_ip with the end IP address of the network segment.
