How can I create an instance with the Nova command line client?

You can use Nova command line client to launch an instance. For example, to create a VM from an image while attaching an ephemeral disk, use the following command:

$ nova boot <vm_name> --flavor <flavor_name> --image <image_name> --security-groups <security_group_name> --nic net-id=<network_ID> --ephemeral size=<size_GBs>

• <vm_name>: Name of the instance.
• --flavor <flavor_name>: Name or ID of flavor.
• --image <image_name>: Name or ID of image.
• --security-groups <security_group_name>: Comma separated list of security group names.
• --nic net-id=<network-ID>: Create a NIC on the server.
• --ephemeral size=<size_GBs>: Create and attach a local ephemeral block device of GB.
