Kernel panic: VFS: Unable to mount root fs on 08:08 解决方法

用qemu启动qcow2镜像时，虚拟机报错提示

/lib/sym53c8xx.o: init_module: No such device
insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters
ERROR: /bin/insmod exited abnormally!
VFS: Cannot open root device "808" or 08:08
please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 08:08

 

网上找了一圈都没找到解决方法

主要问题是启动磁盘格式不正确，改成SCSI格式就能正常启动
