2. activate the cloud, e.g. cloud on india
3. set the default key to start VMs, e.g. key default [NAME]
4. set the start name of VMs, which is prefix and index, e.g. label --prefix=test --id=1
5. set image of VMs, e.g. default image

Also, please make sure the group name of the cluster is unique
Options:
--ln=<LoginName> give a login name for the VMs, e.g. ubuntu
--cloud=<CloudName> give a cloud to work on
