是指使用govmomi库来管理和操作VMware vSphere环境中的虚拟机的开机时间。
govmomi是一个用于与VMware vSphere进行交互的Go语言库。它提供了一组功能丰富的API,可以通过编程方式管理和操作vSphere环境中的虚拟机、主机、数据存储和网络等资源。
在使用govmomi库的零点指示中,我们可以通过以下步骤来实现:
import (
"github.com/vmware/govmomi"
"github.com/vmware/govmomi/vim25"
"github.com/vmware/govmomi/vim25/soap"
)
func createClient() (*govmomi.Client, error) {
url := "https://vcenter.example.com/sdk"
username := "username"
password := "password"
// 创建SOAP客户端
soapClient := soap.NewClient(url, true)
// 使用用户名和密码进行身份验证
err := soapClient.Login(context.Background(), url, username, password)
if err != nil {
return nil, err
}
// 创建vSphere客户端
vimClient, err := vim25.NewClient(context.Background(), soapClient)
if err != nil {
return nil, err
}
// 返回vSphere客户端
return &govmomi.Client{
Client: vimClient,
RoundTripper: soapClient,
}, nil
}
func getVirtualMachine(client *govmomi.Client, vmName string) (*object.VirtualMachine, error) {
// 获取根目录
rootFolder := client.ServiceContent.RootFolder
// 创建一个对象导航器
navigator := client.ServiceContent.SearchIndex
// 根据虚拟机名称查找虚拟机对象
vm, err := navigator.FindByInventoryPath(context.Background(), vmName)
if err != nil {
return nil, err
}
// 返回虚拟机对象
return vm.(*object.VirtualMachine), nil
}
func setPowerOnTime(vm *object.VirtualMachine, powerOnTime time.Time) error {
// 创建一个虚拟机配置对象
configSpec := types.VirtualMachineConfigSpec{
Tools: &types.ToolsConfigInfo{
ToolsUpgradePolicy: string(types.ToolsUpgradePolicyUpgradeAtPowerCycle),
},
ScheduledHardwareUpgradeInfo: &types.ScheduledHardwareUpgradeInfo{

ScheduledHardwareUpgradeStatus: []types.ScheduledHardwareUpgradeStatus{
{
ScheduledHardwareUpgradeStatus: string(types.ScheduledHardwareUpgradeStatusInfoScheduled),
ScheduledHardwareUpgradeTime: powerOnTime,
},
},
},
}
// 执行虚拟机配置更改
task, err := vm.Reconfigure(context.Background(), configSpec)
if err != nil {
return err
}
// 等待任务完成
err = task.Wait(context.Background())
if err != nil {
return err
}
return nil
}

defer client.Logout(context.Background())
// 获取虚拟机对象
vm, err := getVirtualMachine(client, "vm-1")
if err != nil {
fmt.Println("Failed to get virtual machine:", err)
return
}
// 设置开机时间为当前时间加10分钟
powerOnTime := time.Now().Add(10 * time.Minute)
err = setPowerOnTime(vm, powerOnTime)
if err != nil {
fmt.Println("Failed to set power on time:", err)
return
}
fmt.Println("Power on time set successfully:", powerOnTime)
}
func createClient() (*govmomi.Client, error) {
url := "https://vcenter.example.com/sdk"
