在某一个计算节点上同时创建多台虚拟机

gistfile1.txt

通过availability_zone参数可以将虚拟机强制调度到指定的计算节点，但是默认的该参数只能由admin使用，若要普通用户使用，在nova的policy.json中，将"compute:create:forced_host": "is_admin:True"，这条规则改为"compute:create:forced_host": ""


命令行：

nova boot --image c796de54-25f8-405e-afdd-e03003a9e62a --nic net-id=ba05e057-1eb8-4cb2-af58-9b99a72df5ed --flavor 2 --availability_zone nova:server-76 vm


API:

1. 首先获得token

POST http://10.1.0.39:35357/v3/auth/tokens

{
   "auth":{
      "identity": {
         "methods": ["password"],
         "password": {
            "user": {
               "domain": {
                  "id": "7a84434c3283421cac31d98e65ac5d72"
               },
               "name": "guangyu_7a84434c3283421cac31d98e65ac5d72",
               "password": "rachel"
            }
         }
      },
      "scope":{
         "project": {
            "domain": {
              "id": "7a84434c3283421cac31d98e65ac5d72"           
            },
            "id": "6366f4fe38f54c3a96c62e90c088490a"
          }
      }
   }
}

返回的token在response的header中。


2. 在server-76上同时创建3台虚拟机：

POST http://10.1.0.39:8774/v2/6366f4fe38f54c3a96c62e90c088490a/servers

header:
X-Auth-Token = e4ddd10f49fa44ceae7791f5b8360dbb
Content-Type = application/json

body:
{
   "server":{
      "name":"test_slow",
      "imageRef":"c796de54-25f8-405e-afdd-e03003a9e62a",
      "flavorRef":"c40bf599-a979-4404-8332-5a23f75a66cd",
      "max_count":3,
      "min_count":3,
      "networks":[
         {
            "uuid":"ba05e057-1eb8-4cb2-af58-9b99a72df5ed"
         }
      ],
     "availability_zone": "nova:server-76"
   }
}
