Re: [Xen-users] kernel panics??
So where would it be reading that script from? Somewhere in the boot there is a line saying fstab.sys not found loading defaults. I have tried renaming the fstab to fstab.sys but this still gives the same error. I am correct in thinking that it is referring to the fstab in the guest file structure.
thanks
Alex

hello again!
right im trying to boot a guest cloned from the host os.
I have followed the instructions in the wiki
I am getting switchroot: mount failed: No such file or directory
i have created a new ramdisk and my config file points to it, are there things other than scsi drivers that cause this issue?
thanks
