ก่อนอื่นก็ทำการหา ID กับ Name ของ Host ที่จะลบก่อน โดยคลิก Remove ด้วย GUI ตามปกติ จากนั้นคลิกที่ ViewScript เราก็จะได้ ID Host ที่เราจะลบดังภาพ เพื่อเอาไปลบใน ฐานข้อมูล


จากนั้นเอา ID แทนค่าตัวแปรใน 'YourVMHostID' และชื่อของ Host ใน 'YourVMHostName' แล้ว Execute ใน Microsoft SQL Server Management Studio

โค๊ด: [Select]
-- Define the name of the VMM Database --
USE VirtualManagerDB;

DECLARE @DeleteHostId GUID;
DECLARE @DeleteHostName NVARCHAR;
DECLARE @DatabaseName NVARCHAR;

GO

เมื่อลบออกแล้วเราก็สามารถ Add Hyper-V Host เข้าไปใน System Center ได้ใหม่แล้วล่ะครับ
