用JAVA控制ESXi虚拟机

分类： 虚拟化

2011-06-15 12:52:18

免费版的VMWare ESXi 从v3.5 u3开始，禁止了SDK和vCli的“写”调用。
也就是说，从ESXi 3.5u3开始，我们不能用SDK或者vCLI命令行，控制免费版ESXi上运行的虚拟机了，不能对其进行重起，关机等任何“写”操作。
后来无意中在网上发现了一个叫esxi-control.pl的脚本，可以用来控制免费版ESXi上的虚拟机，地址如下

脚本是用Perl写的，通过模拟vSphere Client发出的SOAP消息来控制ESXi.但是这个Perl脚本 仍然需要调用Perl-vCLI去获得虚拟机的id信息。我想既然能够模拟SOAP的控制消息，那也一定能模拟读取虚拟机信息的消息啊，但是平时用Perl很少，所以干脆就用JAVA写了一个实现。

先说说程序的原理，
程序调用Apache的httpclient来完成SOAP消息的发送与接受。

第一步，发送下列SOAP消息来建立连接与身份认证，$USERNAME$和$PASSWORD$为ESXi主机的登陆用户名和密码
  1. <soap:Envelope xmlns:xsd="" xmlns:xsi="-instance" xmlns:soap="">
  2.     <soap:Body>
  3.         <Login xmlns="urn:internalvim25">
  4.             <_this xsi:type="SessionManager" type="SessionManager" serverGuid="">ha-sessionmgr</_this>
  5.             <userName>$USERNAME$</userName>
  6.             <password>$PASSWORD$</password>
  7.             <locale>en_US</locale>
  8.         </Login>
  9.     </soap:Body>
  10. </soap:Envelope>
第二步，获取当前已连接主机上的虚拟机列表，SOAP消息如下
  1. <soapenv:Envelope xmlns:soapenv="" xmlns:xsd="" xmlns:xsi="-instance">
  2.         <soapenv:Body>
  3.                 <RetrieveProperties xmlns="urn:vim25">
  4.                         <_this type="PropertyCollector">ha-property-collector</_this>
  5.                         <specSet>
  6.                                 <propSet>
  7.                                         <type>HostSystem</type>
  8.                                         <all>0</all>
  9.                                         <pathSet>vm</pathSet>
  10.                                 </propSet>
  11.                                 <objectSet>
  12.                                         <obj type="HostSystem">ha-host</obj>
  13.                                 </objectSet>
  14.                         </specSet>
  15.                 </RetrieveProperties>
  16.         </soapenv:Body>
  17. </soapenv:Envelope>
第三步，第二步返回的消息里面只有虚拟机的ID,但是用户一般是不知道虚拟机的ID是干啥的，所以，我们需要虚拟机的名称等其它信息，所以发送下面的消息用来获取虚拟机其它的信息,包括虚拟机的名称，虚拟机的网络名称，IP地址，开关机状态以及VMWareTool的运行情况。
其中的$VMID$就是要获取具体信息的虚拟机ID
可以有多个，用来一次性获取多台虚拟机的信息
  1. <soapenv:Envelope xmlns:soapenv="" xmlns:xsd="" xmlns:xsi="-instance">
  2.     <soapenv:Body>
  3.             <RetrieveProperties xmlns="urn:vim25">
  4.                 <_this type="PropertyCollector">ha-property-collector</_this>
  5.                     <specSet>
  6.                         <propSet>
  7.                             <type>VirtualMachine</type>
  8.                             <all>0</all>
  9.                             <pathSet>name</pathSet>
  10.                             <pathSet>guest.hostName</pathSet>
  11.                             <pathSet>runtime.powerState</pathSet>
  12.                             <pathSet>guest.ipAddress</pathSet>
  13.                             <pathSet>guest.toolsRunningStatus</pathSet>
  14.                         </propSet>
  15.             <objectSet>
  16.                 <obj type="VirtualMachine">$VM1ID$</obj>
  17.             </objectSet>
  18.             <objectSet>
  19.                 <obj type="VirtualMachine">$VM2ID$</obj>
  20.             </objectSet>
  21.                     </specSet>
  22.             </RetrieveProperties>
  23.     </soapenv:Body>
  24. </soapenv:Envelope>
第四步，到这里，我们的准备工作就结束了，可以发送SOAP的控制消息，控制虚拟机的开关机/重起等操作了，这部分SOAP消息esxi-control.pl做得比较深入，值得借鉴。
这里只举一个重起虚拟机的SOAP消息做例子, $VMID$就是要被重起的虚拟机的ID
  1. <soap:Envelope xmlns:xsd="" xmlns:xsi="-instance" xmlns:soap="">
  2.     <soap:Body>
  3.         <ResetVM_Task xmlns="urn:internalvim25">
  4.             <_this xsi:type="VirtualMachine" type="VirtualMachine" serverGuid="">$VMID$</_this>
  5.         </ResetVM_Task>
  6.     </soap:Body>
  7. </soap:Envelope>
第五步，断开连接
  1. <soap:Envelope xmlns:xsd="" xmlns:xsi="-instance" xmlns:soap="">
  2.     <soap:Body>
  3.         <Logout xmlns="urn:internalvim25">
  4.             <_this xsi:type="ManagedObjectReference" type="SessionManager" serverGuid="">ha-sessionmgr</_this>
  5.             </Logout>
  6.     </soap:Body>
  7. </soap:Envelope>

JAVA实现代码如下
  1. package java_vc;
