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.
NAME_OR_ID server name or ID
KEYPAIR_NAME Name of the openstack keypair to be used to create VM. Note this is not a path to key.
NEWNAME New name of the VM while renaming.
Options:
--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_OR_ID 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_OR_ID 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 delete vms without user's confirmation
--command=COMMAND
specify the commands to be executed
--new=NEWNAME Specify the new name for a VM while renaming.
By default, this will be set to <username>-<count> format.
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']

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.
NAME_OR_ID server name or ID
KEYPAIR_NAME Name of the openstack keypair to be used to create VM. Note this is not a path to key.
NEWNAME New name of the VM while renaming.
Options:
--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_OR_ID 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_OR_ID 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 delete vms without user's confirmation
--command=COMMAND
specify the commands to be executed
--new=NEWNAME Specify the new name for a VM while renaming.
By default, this will be set to <username>-<count> format.
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']
