As you can see in the figure, different service objects can be obtained from the OpenStack client as needed. The computing service is used to manage CVMs. A CVM can be created by using data such as host type, image, key pair and network. It can pause, resume, stop, start, restart and other operations on the CVM. You can also get web vnc-based console links.
