Waiting for device dev/disk/by-id/ata-...-part2 to appear

問題：平台：Oralce VM Virtualbox的虛擬機器Opensuse11.4匯出該機器的OVA檔案後，把該OVA檔案匯入虛擬機器，開機啟動時報如下錯誤：

分析：原因是Opensuse的一個新的預設設定，從10Sp1版本開始，存放裝置（硬碟）由原來的名稱相關變為ID相關。
說明：以前的硬碟描述為sda、sdb等，硬碟的分區描述為sda1、sda2、sda3等；而如今硬碟與分區的新描述，例如：/dev/disk/by-id/ata-TOSHIBA-MK1246GSX-28FGTI70T/dev/disk/by-id/ata-ST380013AS_4MR2NSD8其分區描述，例如：/dev/disk/by-id/ata-TOSHIBA-MK1246GSX-28FTTI70T-part1/dev/disk/by-id/ata-TOSHIBA-MK1246GSX-28FTTI70T-part2問題在於，在虛擬機器Opensuse機器上硬碟是用ID來描述在設定檔做相關記錄的，而目標機器（即存放OVA檔案的物理機）硬碟是不一樣的，會有不一樣的ID記錄名稱，所以匯入後的機器才無法找到硬碟而不能啟動成功。

 

解決：只需在原來的Opensuse機器上修改兩個設定檔即可。這兩個檔案是
/etc/fstab
/boot/grub/menu.lst
在這兩個檔案中，我們需要找出每一個類似下面例子的名稱，例子如下：
/dev/disk/by-id/ata-TOSHIBA-MK1246GSX-28FGTI70T-part1然後把它們改成
/dev/sda1
注意分區名稱對應如下：
-part1  ->  sda1
-part2  ->  sda2

步驟如下：
確保有許可權修改檔案，開啟檔案，修改完畢後，按ESC退出輸入模式，然後輸入:wq儲存修改。

sudo vi /etc/fstabsudo vi /boot/grub/menu.lst

重啟電腦確認一切照常，然後就可以匯出OVA檔案了。

舉例：以下是這兩個檔案修改前後的內容變化：
