這篇介紹的是Windows 2008 R2的Hyper-V Best Practices Analyzer

這個工具可以快速的檢查出目前Hyper-V非最佳化的設定，並給予建議跟修正的方向

首先需要先將KB977238安裝在Hyper-V Server上

KB977238：Windows Server 2008 R2 x64 Edition 之 HYPER-V 的 Best Practices Analyzer 更新

安裝完並不需要重新開機，請放心使用

安裝完後，就可以到【伺服器管理員】→【Hyper-V】→【Best Practices Analyzer】去掃描是否有未最佳化的設定

接著就可以看他的原因、跟解決方法

以上是安裝有GUI版本的Hyper-V，如果是使用Server Core版本的話，則是使用Powershell

需要先Import ServerManager的Module(因為BPA是ServerManager的組件)

語法：

Import-Module ServerManager

Import-Module BestPractices

接著就是執行BPA

Invoke-Bpamodel Microsoft/Windows/Hyper-V

然後，去取得BPA的Report

Get-BpaResult Microsoft/Windows/Hyper-V

或者是匯出成csv格式

Get-BpaResult Microsoft/Windows/Hyper-V | Export-Csv C:\Hyper-V_BPA.csv

您也可以使用微軟原廠所提供的PowerShell Script去將資訊匯出成csv格式(預設存放csv的路徑是User的Desktop)

路徑的部份，您可以修改$OutputPath的參數例如：$OutputPath = “C:\Hyper-V_BPA”

# the following command will run Hyper-V Best Practices Analyzer (KB977238) and exports the result in CSV format c:\temp\Hyperv_BPA_Report.csv
# Powershell Help:  Get-Help about_BestPractices
# Hyper-V BPA ID: Microsoft/Windows/Hyper-V
