[Xen-devel] [Xen-users] XENBUS waiting timeout

[jinho hwang <hwang.jinho@xxxxxxxxx>]

Hi,

I have used disk image to copy host fs to image file and boot a guest system. But, the system is dropped to shell and it also says that it can't find /dev/xvda1 which is the root fs. I have defined it in the configuration file as follows:

disk = [ 'tap:aio:/xen/XenGuest1.img,xvda1,w', 'tap:aio:/xen/XenGuest1.swap,xvda2,w' ]

root = "/dev/xvda1 ro"

Also, modified the fstab as follows:

/dev/xvda1       /               ext3    defaults          1       1

/dev/xvda2       none            swap    sw                0       0

none             /dev/pts        devpts  gid=5,mode=620    0       0

none             /dev/shm        tmpfs   defaults          0       0

none             /proc           proc    defaults          0       0

none             /sys            sysfs   defaults          0       0

The following is the error shown in the console.

Gave up waiting for root device.  Common problems:

 - Boot args (cat /proc/cmdline)

   - Check rootdelay= (did the system wait long enough?)

   - Check root= (did the system wait for the right device?)

 - Missing modules (cat /proc/modules; ls /dev)

ALERT!  /dev/xvda1 does not exist.  Dropping to a shell!

If anybody has any idea, please let me know. 

Thank you,

Jinho
