            Arguments:
                COMMAND        positional arguments, the commands you want to
                               execute on the server(e.g. ls -a) separated by ';',
                               you will get a return of executing result instead of login to
                               the server, note that type in -- is suggested before
                               you input the commands
                NAME           server name. By default it is set to the name of last vm from database.

            Description:
                commands used to boot, start or delete servers of a cloud

                vm default [options...]     Displays default parameters that are set for VM boot.
                vm boot [options...]        Boots servers on a cloud, user may specify
                                            flavor, image .etc, otherwise default values
                                            will be used, see how to set default values
                                            of a cloud: cloud help
                vm start [options...]       Starts a suspended or stopped vm instance.
                vm stop [options...]        Stops a vm instance .
                vm delete [options...]      delete servers of a cloud, user may delete
                                            a server by its name or id, delete servers
                                            of a group or servers of a cloud, give prefix
                                            and/or range to find servers by their names.
                                            Or user may specify more options to narrow
                                            the search
                vm floating_ip_assign [options...]   assign a public ip to a VM of a cloud
                vm ip show [options...]     show the ips of VMs
                vm login [options...]       login to a server or execute commands on it
                vm list [options...]        same as command "list vm", please refer to it
                vm status [options...]      Retrieves status of last VM booted on cloud and displays it.

            Tip:
                give the VM name, but in a hostlist style, which is very
                convenient when you need a range of VMs e.g. sample[1-3]
                => ['sample1', 'sample2', 'sample3']
                sample[1-3,18] => ['sample1', 'sample2', 'sample3', 'sample18']

                               execute on the server(e.g. ls -a) separated by ';',
                               you will get a return of executing result instead of login to
                               the server, note that type in -- is suggested before
                               you input the commands
                NAME           server name. By default it is set to the name of last vm from database.

            Description:
                commands used to boot, start or delete servers of a cloud

                vm default [options...]     Displays default parameters that are set for VM boot.
                vm boot [options...]        Boots servers on a cloud, user may specify
                                            flavor, image .etc, otherwise default values
                                            will be used, see how to set default values
                                            of a cloud: cloud help
                vm start [options...]       Starts a suspended or stopped vm instance.
                vm stop [options...]        Stops a vm instance .
                vm delete [options...]      delete servers of a cloud, user may delete
                                            a server by its name or id, delete servers
                                            of a group or servers of a cloud, give prefix
                                            and/or range to find servers by their names.
                                            Or user may specify more options to narrow
                                            the search
                vm floating_ip_assign [options...]   assign a public ip to a VM of a cloud
                vm ip show [options...]     show the ips of VMs
                vm login [options...]       login to a server or execute commands on it
                vm list [options...]        same as command "list vm", please refer to it
                vm status [options...]      Retrieves status of last VM booted on cloud and displays it.

            Tip:
                give the VM name, but in a hostlist style, which is very
                convenient when you need a range of VMs e.g. sample[1-3]
                => ['sample1', 'sample2', 'sample3']
                sample[1-3,18] => ['sample1', 'sample2', 'sample3', 'sample18']

                               execute on the server(e.g. ls -a) separated by ';',
                               you will get a return of executing result instead of login to
                               the server, note that type in -- is suggested before
                               you input the commands

            Description:
                commands used to boot, start or delete servers of a cloud

                vm default [options...]     Displays default parameters that are set for VM boot.
                vm boot [options...]        Boots servers on a cloud, user may specify
                                            flavor, image .etc, otherwise default values
                                            will be used, see how to set default values
                                            of a cloud: cloud help
                vm start [options...]       Starts a suspended or stopped vm instance.
                vm stop [options...]        Stops a vm instance .
                vm delete [options...]      delete servers of a cloud, user may delete
                                            a server by its name or id, delete servers
                                            of a group or servers of a cloud, give prefix
                                            and/or range to find servers by their names.
                                            Or user may specify more options to narrow
                                            the search
                vm floating_ip_assign [options...]   assign a public ip to a VM of a cloud
                vm ip_show [options...]     show the ips of VMs
                vm login [options...]       login to a server or execute commands on it
                vm list [options...]        same as command "list vm", please refer to it
                vm status [options...]      Retrieves status of last VM booted on cloud and displays it.

            Tip:
                give the VM name, but in a hostlist style, which is very
                convenient when you need a range of VMs e.g. sample[1-3]
                => ['sample1', 'sample2', 'sample3']
                sample[1-3,18] => ['sample1', 'sample2', 'sample3', 'sample18']
