有没有办法使用 powershell 从 Hyper-V 获取虚拟机操作系统名称？

Question

我正在 HYPER-V 主机上编写脚本以获取 VM 来宾信息。有没有办法使用 powershell 从 Hyper-V 获取虚拟机操作系统名称？

有几个使用 (Get-WmiObject Win32_OperatingSystem -ComputerName $vmName).name 的示例，但由于域限制，我应该直接从 Hyper-V 获取此信息。

另外，我正在使用 powershell 的 hyper-v 模块，但我看不到任何与 OS 相关的 cmdlet。

Answer 1

除非您使用的是 SCVMM，否则无法通过 Hyper-V PowerShell cmdlet 获得来宾 OS 详细信息。

您必须像已经找到的那样查询来宾本身。

Answer 2

这可以从来宾内部交换项目中检索到。

# Filter for parsing XML data
filter Import-CimXml 
{ 
   # Create new XML object from input
   $CimXml = [Xml]$_ 
   $CimObj = New-Object -TypeName System.Object 

   # Iterate over the data and pull out just the value name and data for each entry
   foreach ($CimProperty in $CimXml.SelectNodes("/INSTANCE/PROPERTY[@NAME='Name']")) 
      { 
         $CimObj | Add-Member -MemberType NoteProperty -Name $CimProperty.NAME -Value $CimProperty.VALUE 
      } 

   foreach ($CimProperty in $CimXml.SelectNodes("/INSTANCE/PROPERTY[@NAME='Data']")) 
      { 
         $CimObj | Add-Member -MemberType NoteProperty -Name $CimProperty.NAME -Value $CimProperty.VALUE 
      } 

   # Display output
   $CimObj 
} 

# Prompt for the Hyper-V Server to use
$HyperVServer = Read-Host "Specify the Hyper-V Server to use (enter '.' for the local computer)"

# Prompt for the virtual machine to use
$VMName = Read-Host "Specify the name of the virtual machine"

# Get the virtual machine object
$query = "Select * From Msvm_ComputerSystem Where ElementName='" + $VMName + "'"
$Vm = gwmi -namespace root\virtualization\v2 -query $query -computername $HyperVServer

# Get the KVP Object
$query = "Associators of {$Vm} Where AssocClass=Msvm_SystemDevice ResultClass=Msvm_KvpExchangeComponent"
$Kvp = gwmi -namespace root\virtualization\v2 -query $query -computername $HyperVServer

Write-Host
Write-Host "Guest KVP information for" $VMName

# Filter the results
try {
    $Kvp.GuestIntrinsicExchangeItems | Import-CimXml | where Name -eq "OSName"
}
catch {
    Write-Host "Not found"
}

我无法在 PowerShell 7.1 版上运行 t1meless' 脚本，因为 gwmi 在 7.1 中已弃用，来源 MS Docs and GitHub。我为 PS 7.1.

重写了脚本

# Script for retrieving Hyper-V Guest Operating System.
# Tested on PowerShell 7.1

# Prompt for the Hyper-V Server to use
$hyper_v_server = Read-Host "Specify the Hyper-V Server to use (enter '.' for the local computer)"

# Prompt for the virtual machine to use
$vm_name = Read-Host "Specify the name of the virtual machine"

# Check if VM exists and is running. This script doesn't work if the VM is stopped.
# Capture error output, source: 
$vm_not_found = $($vm_state = (Get-VM $vm_name).state) 2>&1

if ($vm_not_found -ne $null) {
    Write-Host "$vm_name VM was not found."
    exit
}

if ($vm_state -eq "Off") {
    Write-Host "Cannot retrieve information of $vm_name. The VM is stopped. Only running VM information can be retrieved."
    exit
}

# Get the virtual machine object
$query = "Select * From Msvm_ComputerSystem Where ElementName='" + $vm_name + "'"
$vm = Get-CimInstance -namespace root\virtualization\v2 -query $query -computername $hyper_v_server

# Get associated information
$vm_info = Get-CimAssociatedInstance -InputObject $vm

Write-Host "Guest information for" $vm_name

# Select only required information
$vm_info | Where GuestOperatingSystem |
    Select -Property GuestOperatingSystem |
    Format-List *
