在把 Virtual Server 2005 的虚拟机迁过去 Windows Server 2008 Hyper-V 以后,原来有些虚拟机开了 undo disk 的,发现在 Hyper-V 中没有合并选项,于是又重新安装了 Virtual Server 2005 SP1, 但是合并的时候失败,出错提示如下:

“Virtual Server was unable to commit the changes made during the current session of “[VPC NAME]“. The cause of this problem is that the parent virtual hard disk is a part of a saved state. Your changes will be kept for the next time you start this virtual machine.”
