Hi there guys
As a test, I started using the same kernel and initramfs like in Dom0
which i know it works, but when starting up DomU I've get.
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!
Pid: 1, comm: init Not tainted 2.6.31.13 #14
I've got the same error while setting up Dom0 and was a problem with
the scsi modules which I included in the kernel and not in the
initramfs, my bad !!
My config file looks this.
#----------------------------------------------------------------------------
# Kernel image file.
kernel = "/boot/vmlinuz-2.6.31.13"
# Optional ramdisk.
ramdisk = "/boot/initrd-2.6.31.13.img"
disk = [ 'phy:VG-NW/root,sda1,w','phy:VG-NW/swap,sda2,w' ]
Also copied the /lib/modules/kernel_version to the *guest* partition.
What am I missing?
Thanks for your time and support
