详细说明

The Set-VMFirmware cmdlet sets the firmware configuration of a Generation 2 virtual machine.

参数

-BootOrder<VMComponentObject[]>

Specifies an array of devices. The boot order determines the order of the devices from which to boot. 此参数可接受的值如下：

  -- VMBootSource
  -- VMNetworkAdapter
  -- HardDiskDrive
  -- DVDDrive

The VMBootSource value describes a boot entry in firmware nonvolatile Random Access Memory (NVRAM).

-ComputerName<String[]>

Specifies the names of the Hyper-V hosts whose firmware configuration you want to modify.

-EnableSecureBoot<OnOffState>

Specifies whether to enable secure boot. 此参数可接受的值如下：

  -- On
  -- Off

Secure boot uses a public key infrastructure that protects the integrity of the operating system.

-FirstBootDevice<VMComponentObject>

Specifies the device from which to attempt to boot from first. 此参数可接受的值如下：

  -- VMBootSource
  -- VMNetworkAdapter
  -- HardDiskDrive
  -- DVDDrive

The VMBootSource value describes a boot entry in firmware NVRAM.

-Passthru

返回一个表示你正在处理的项的对象。默认情况下，此 cmdlet 将不产生任何输出。

-PreferredNetworkBootProtocol<IPProtocolPreference>

Specifies the IP protocol version to use during a network boot.

-VM<VirtualMachine[]>

Specifies the virtual machine objects for which want to modify the firmware configuration. To obtain a virtual machine object, use the Get-VM cmdlet.

-VMFirmware<VMFirmware[]>

Specifies an array of virtual machine firmware configurations. The cmdlet sets the firmware configurations you specify.

-VMName<String[]>

Specifies an array of names of virtual machines for which you want to modify the firmware configuration.

-Confirm

运行 cmdlet 之前提示你进行确认。

-WhatIf

显示如果运行 cmdlet 则会发生什么情况。cmdlet 未运行。

<CommonParameters>

此 cmdlet 支持通用参数：-Verbose、-Debug、-ErrorAction、-ErrorVariable、-OutBuffer 和 -OutVariable。有关详细信息，请参阅 about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

输入

输入类型是指可通过管道传送给 cmdlet 的对象的类型。

输出

输出类型是 cmdlet 所发出对象的类型。

• Microsoft.HyperV.Powershell.VMFirmware

注意

• Note: This cmdlet is supported only when run against Generation 2 virtual machines.

示例

Example 1

This example enables secure boot functionality on the virtual machine “Test VM”.

PS C:\> Set-VMFirmware "Test VM" -EnableSecureBoot On

Example 2

This example sets the virtual machine “Test VM” to boot off of the VM network adapter object stored in $vmNetworkAdapter. This object was acquired using get-VMNetworkAdapter.

PS C:\> Set-VMFirmware "Test VM" -FirstBootDevice $vmNetworkAdapter

Example 3

Sets the boot order for the virtual machine “Test VM”. $vmNetworkAdapter contains a VM Network Adapter object (acquired using get-VMNetworkAdapter) and $vmHardDiskDrive contains a VM hard disk object (acquired using get-VMHardDiskDrive). Any existing boot entries not specified by this command will be removed from the virtual machine.

PS C:\> Set-VMFirmware "Test VM" -BootOrder $vmNetworkAdapter, $vmHardDiskDrive
