Linux qemu启动内核rootfs挂载失败VFS: Cannot open root device问题解决方案

本文介绍了在使用QEMU模拟Linux系统时遇到的rootfs挂载失败的问题,分析了可能的错误原因,并提供了解决方案。同时,针对高版本内核中GDB断点不停的问题,提出了启用'nokaslr'参数来解决问题。此外,还提及了GDB调试时需要关注的内核配置选项。

rootfs挂载失败

But using this QEMU emulation setup I tried to produce minimal examples of every possible failure type to help you debug your problem.

In that simple setup, QEMU emulates a system with:

  • a single virtio disk which represents a hard disk or SDD of real hardware
  • that virtio disk has a raw unpartitioned ext4 image in it. In normal operation, that device would appear under /dev/vda (v is the indicator letter for virtio, if it were partitioned the partitions would be /dev/vda1/dev/vda2, etc.)

The possible errors you could get are:

  1. Linux cannot read bytes from the disk.

    This could be either because the disk is broken, or be
