我們在博客中能夠知道? 能用命令行定向創建虛擬機到指定計算節點

http://blog.csdn.net/qq_21398167/article/details/46710175

nova boot --image fedora ?--flavor 1 ?test1 ?--availability-zone nova:node-1

為此我想看看是否能通過API? 創建這種instance

通過查看 官網中的開源API?? 能夠看到

http://blog.csdn.net/qq_21398167/article/details/46530305

中有這樣一個API：

create(name,image,flavor,meta=None, files=None, reservation_id=None,min_count=None,max_count=None,security_groups=None, userdata=None, key_name=None, availability_zone=None, block_device_mapping=None,block_device_mapping_v2=None,nics=None,scheduler_hints=None,config_drive=None, disk_config=None,**kwargs)

Create (boot) a new server.

Parameters:

name – Something to name the server. image – The Image to boot with. flavor – The Flavor to boot onto. meta – A dict of arbitrary key/value metadata to store for thisserver. Both keys and values must be <=255 characters. files – A dict of files to overrwrite on the server upon boot.Keys are file names (i.e./etc/passwd) and valuesare the file contents (either as a string or as afile-like object). A maximum of five entries is allowed,and each file must be 10k or less. reservation_id – a UUID for the set of servers being requested. min_count – (optional extension) The minimum number ofservers to launch. max_count – (optional extension) The maximum number ofservers to launch. security_groups – A list of security group names userdata – user data to pass to be exposed by the metadataserver this can be a file type object as well or astring. key_name – (optional extension) name of previously createdkeypair to inject into the instance. availability_zone – Name of the availability zone for instanceplacement. block_device_mapping – (optional extension) A dict of blockdevice mappings for this server. block_device_mapping_v2 – (optional extension) A dict of blockdevice mappings for this server. nics – (optional extension) an ordered list of nics to beadded to this server, with information aboutconnected networks, fixed IPs, port etc. scheduler_hints – (optional extension) arbitrary key-value pairsspecified by the client to help boot an instance config_drive – (optional extension) value for config driveeither boolean, or volume-id disk_config – (optional extension) control how the disk ispartitioned when the server is created. possiblevalues are ‘AUTO’ or ‘MANUAL’.

這個API 中有同樣參數? ?--availability-zone

所以直接在使用這個API 的時候將默認參數 None? 替換成你想定向的那個計算節點名就Ok了！
