linux – 内核恐慌 – 创建自己的AMI(亚马逊机器映像)

概述我创建了自己的AMI并在Amazon EC2上注册了它.但是在AMI启动时我收到以下错误： Kernel panic – not syncing: VFS: Unable to mount root fs on unknown-block(8,1) 图像在本地运行没有任何问题. fstab包含： proc /proc proc defaults 我创建了自己的AMI并在Amazon EC2上注册了它.但是在AMI启动时我收到以下错误：

Kernel panic – not syncing: VFS: Unable to mount root fs on unkNown-block(8,1)

图像在本地运行没有任何问题.

fstab包含：

proc          /proc   proc     defaults                      0 0/dev/sda1     /       ext3     relatime,errors=remount-ro    0 1

该图像是使用以下命令创建的

ec2-bundle-image -i image.raw -r i386 -c cert-xxx.pem -k pk-xxx.pem --user 123456
