本文介绍如何使用vSphere for Java SDK实现虚拟机的自动化配置与部署，包括虚拟机模板克隆、资源分配及网络设置等关键步骤。

vSphere for Java类库：vijava

虚拟机配置类

package com.vmware.vcenter_event.VirtualMachine;

import com.vmware.vim25.CustomizationIPSettings;
import com.vmware.vim25.mo.ClusterComputeResource;
import com.vmware.vim25.mo.Datastore;
import com.vmware.vim25.mo.Folder;
import lombok.Data;


@Data
public class VirtualMachineConfig {

    private String vmName;

    private String hostName;

    private String domain;

    private Integer cpuNums;

    private Long memoryGB;

    private Integer diskGB;

    private Folder folder;

    private Datastore datastore;

    private ClusterComputeResource clusterComputeResource;

    private CustomizationIPSettings ipSettings;

}
