用于检测 Hyper-V Gen 2 VM 与 Gen 1 VM 的 PowerShell 代码（运行来自 VM 本身）

Question

在 VM 的 PowerShell 脚本运行中，我想以编程方式确定该 VM 是第 1 代 Hyper-V VM 还是第 2 代 Hyper-V VM。假设 VM 是运行与第 2 代 VM 中的运行兼容的 Windows 版本。

这个问题不是关于检测 Hyper-V 的。鉴于脚本在 VM 上是运行而 VM 在 Hyper-V 上是运行，我如何确定 VM 的世代号？

可能的线索：

Sample C++ MSDN code to query VM Generation ID - 也许有一种方法可以将此 C++ 代码转换为 C#，然后在运行时使用 Add-Type 动态编译它？我认为这可能是最好的方法，但它超出了我的技能水平。

VMDE Project on GitHub - 有各种检测VM平台的方法，但不是用PowerShell写的，要实现它超出了我的技能水平

提前致谢！

Answer 1

不像您已经发现的那样是本地的，但解决方法可能是调用远程计算机运行ning hyper-v，然后运行那里的 Get-VM cmdlet 来检查您的来宾代号。

Invoke-Command -ComputerName 'SomeRemoteServerNameWithHyperV' {
    Get-VM -ComputerName 'YourHostName' | 
    Select-Object -Property Name, Generation
}

更新

根据您的 Device Guard 检查。试试这个...

Get-CimInstance –ClassName Win32_DeviceGuard –Namespace root\Microsoft\Windows\DeviceGuard

Answer 2

我假设如果系统是 Hyper-V VM 并且它是运行ning UEFI（而不是 BIOS），那么它就是 Hyper-V Gen 2 VM。同样，如果它是 Hyper-V VM 而不是运行ning UEFI，则它必须是 Hyper-V Gen 1 VM。在撰写本文时，这些假设是正确的。

我今天下午参加了编码马拉松比赛，并有一个 可行的解决方案 ，最容易阅读和维护的是我的 GitHub：https://github.com/franklesniak/PowerShell_Resources/blob/master/Get-HyperVVMGenerationNumberFromWithinVM.ps1

不幸的是，代码超出了 Stack Overflow 上 post 的允许限制，因此我无法在 post 中提供代码。但是，感兴趣的函数是 Get-HyperVVMGenerationNumberFromWithinVM 并且我将其包含在下面，尽管 它不会运行如果没有加载先决条件函数，包含在GitHublink.
