Question

我正在使用XenServer 6.5

在Java中，我使用SDK库

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

然后我用模板创建我的实例。

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));

创建实例后，我尝试启动它。

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

但它返回

我在互联网上搜索，发现了 create函数没有两个布尔参数：

vm.start(connection);

但我尝试使用不同版本的Maven：

vm.start(connection, false, false);

错误消息没有太多信息。我错过了任何步骤吗？

Answer 1

我很抱歉这么晚回答，但我昨天刚看到这个问题，我想在回答你之前先测试一下。
关于内存问题，任何内存设置都是以字节为单位，因此，参数很长（允许大容量内存配置）。你只能在两个内存中设置新的VM，静态和动态，低于Spectrum！
考虑到这一点，我的假设是你的内存限制太低，因为 GUEST OS 有内存限制（特别是Windows）。在这个blog中，您可以看到与其他虚拟机管理程序相关的客户操作系统的最小/最大内存（但我认为在Xenserver中是相同的）。
无论如何，这个片段对我来说是使用相同的maven依赖，和你一样的xenserver - 6.5 - 。有关vm.start(con,false,false)的更多信息，您可以下载Xenserver 6.5 SDK并查看与VM相关的javadoc。第二个参数是允许在暂停模式下启动，第三个参数是强制启动操作。

       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();
        }

Xenserver Java API启动VM
