Note that the VM will not be ready instantaneously waiting time is mostly determined by the cloud’s available resources. Īccess instance with `ssh -i /home/ubuntu/.config/openstack/sunbeam to the VM over SSH using the provided command.

Sample output: Launching an OpenStack instance. The launch command is used: sunbeam launch ubuntu -name test Verify the cloud by launching a VM called ‘test’ based on the ‘ubuntu’ image (Ubuntu 22.04 LTS). Admin credentials can be obtained in this way (file admin-openrc): sunbeam openrc > admin-openrc The above command provides normal user credentials (file demo-openrc).
