有没有办法使用Powershell从Hyper-V获取VM操作系统名称? [英] Is there a way to get VMs Operating System name from Hyper-V using powershell?

问题描述

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VM操作系统名称?

I'm writing a script on HYPER-V host for getting VMs guest informations. Is there a way to get VMs Operating System name from Hyper-V using powershell?

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

There are several examples using (Get-WmiObject Win32_OperatingSystem -ComputerName $vmName).name but i should get this information directly from Hyper-V because of domain restrictions.

我也正在使用powershell的hyper-v模块，但是我看不到任何与OS相关的cmdlet.

Also i'm using hyper-v module of powershell but i couldn't see any cmdlets related to OS.

推荐答案

可以从访客固有交换项中检索该信息.

This could be retrieved from guest intrinsic exchange items.

# 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"
}
