How to troubleshoot kernel panic in Mac Paralles

Reference :  http://kb.parallels.com/en/10007

 

問題的描述：

今天在嘗試使用puppetlab 提共的vm到parallels使用時，遇到的kernel panic問題，但卻不知道該如何下手，後來就從paralles上面的論壇找到有關kernal panic的debug 方法，然後再從有問題的debug log中找到原來是找不到lvm 的virtual group，然後繼續找就看到原來他是開機的時候嘗試找尋ide硬碟，但轉換後他卻直接使用scsi，所以造成找不到硬碟，才會顯示kernal panic

 

重點：

1.安裝虛擬的serial port，並把開機資料導出文字檔案中

2.修改開機指令，讓開機資料導出到虛擬的serial port中
