的XenServer的Java API啓動VM

Question

我使用的XenServer 6.5

在Java中，我使用SDK庫

<dependency> 
    <groupId>net.java.dev.vcc.thirdparty</groupId> 
    <artifactId>xen-api</artifactId> 
    <version>6.2.0-3.1</version> 
</dependency> 

然後，我創建我的實例與模板。

VM template = VM.getByNameLabel(connection, templateName).iterator() 
       .next(); 
VM vm = template.createClone(connection, instanceName); 
vm.setIsATemplate(connection, false); 
vm.removeFromOtherConfig(connection, "disks"); 
vm.setNameLabel(connection, instanceName); 
vm.setMemoryStaticMin(connection, new Long(256)); 
vm.setMemoryDynamicMin(connection, new Long(256)); 
vm.setMemoryDynamicMax(connection, new Long(256)); 
vm.setMemoryStaticMax(connection, new Long(256)); 
vm.setVCPUsAtStartup(connection, new Long(1)); 

我創建一個實例後，我嘗試啓動它。

VM vm = VM.getByNameLabel(connection, name).iterator().next(); 
vm.start(connection, false, false); 
System.out.println(vm.getPowerState(connection)); 

但它返回

The server failed to handle your request, due to an internal error. The given message may give details useful for debugging the problem.

我在互聯網上搜索，發現 的創造功能沒有對兩個布爾參數：

vm.start(connection); 

但我嘗試不同的版本的Maven：

vm.start(connection, false, false); 

而錯誤信息沒有太多的信息。我錯過了任何步驟？

Answer 1

我真的很抱歉回答這麼晚，但我剛剛看到昨天的問題，我希望在回答你之前測試一些東西。
關於內存問題，任何內存設置都是以字節爲單位的，因爲這個參數很長（爲了允許巨大的內存配置）。只有在兩個內存（靜態和動態）中將新VM設置爲512字節，少於Spectrum ！
考慮到這一點，我的假設是你的內存限制太低，因爲內存限制（特別是Windows）。在此blog中，可以看到與其他虛擬機管理程序相關的guest虛擬機操作系統的最小/最大內存（但我認爲在Xenserver中是相同的）。
無論如何，這個片段正在爲我工​​作，使用相同的maven依賴，和同樣的xenserver - 6.5 - 與你一樣。
有關vm.start(con,false,false)的更多信息，您可以下載Xenserver 6.5 SDK並查看與VM相關的javadoc。第二個參數是允許在暫停模式下啓動，第三個參數是強制啓動操作。

 try 
     { 
      Connection con = new Connection(new URL(url)); 
      Session.loginWithPassword(con, user, pass); 
      String templateName = "template-test"; 
      String instanceName = "testVM"; 
      VM template = VM.getByNameLabel(con, templateName).iterator().next(); 
      VM vm = template.createClone(con, instanceName); 
      vm.setNameLabel(con, instanceName); 
      //This numbers are upper than required minimum for Windows 7 
      //My Guest OS 
      vm.setMemoryStaticMin(connection, 1073741824L); 
      vm.setMemoryDynamicMin(connection, 4294967296L); 
      vm.setMemoryDynamicMax(connection, 1073741824L);    
      vm.setMemoryStaticMax(connection, 4294967296L); 
      vm.setVCPUsAtStartup(con, 1L); 
      vm.provision(con); 
      VM vm2 = VM.getByNameLabel(con, instanceName).iterator().next(); 
      vm2.start(con, false, false); 
      System.out.println(vm2.getPowerState(con)); 
     } 
     catch (Exception e) 
     { 
      e.printStackTrace(); 
     }
