            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.

                KEYPAIR_NAME   Name of the openstack keypair to be used to create VM. Note this is
                               not a path to key.
                NEWNAMES       New names of the VM while renaming.
                OLDNAMES       Old names of the VM while renaming.

            Options:
                --username=USERNAME  the username to login into the vm. If not specified it will be guessed
                                     from the image name and the cloud
                --ip=IP          give the public ip of the server
                --cloud=CLOUD    give a cloud to work on, if not given, selected
                                 or default cloud will be used
                --count=COUNT    give the number of servers to start
                --detail         for table print format, a brief version
                                 is used as default, use this flag to print
                                 detailed table
                --flavor=FLAVOR  give the name or id of the flavor
                --group=GROUP          give the group name of server
                --secgroup=SECGROUP    security group name for the server
                --image=IMAGE    give the name or id of the image
                --key=KEY        specify a key to use, input a string which
                                 is the full path to the private key file
                --keypair_name=KEYPAIR_NAME   Name of the openstack keypair to be used to create VM.
                                              Note this is not a path to key.
                --user=USER      give the user name of the server that you want
                                 to use to login
                --name=NAME      give the name of the virtual machine
                --force          rename/ delete vms without user's confirmation

                                 specify the commands to be executed


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

                vm default [options...]
                    Displays default parameters that are set for vm boot either on the
                    default cloud or the specified cloud.

                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 ssh [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']
