Hello, I am really desperate as I am trying to solve the following issue for almost two weeks now.

First - I have classic hardened AMD_64 gentoo on software raid with boot on md0 (ext3) and md1 (LVM) running with LILO and initrd (the initrd is for LVM2 support).

Now I am trying to make a dom0 kernel for XEN and I am using mbootpack to create the kernel image from xen image, kernel and my initrd. I am following the guides on the internet and I can not make the xen kernel boot.

Code:

lba32
compact
vga=normal
read-only
prompt
timeout=30
serial=0,9600

boot=/dev/md1

image=/boot/vmlinuz-xen0-mpack
  label=xen
  root=/dev/ram0
  append="dom0_mem=256M console=com1,vga noreboot noapic -- noapic rootlvm2root=/dev/lvm-raid/root console=ttyS0"


The output of the console when the xen kernel is booting is:

Code:

I am not very experienced with the XEN but it looks for me, that the xen sources and then a kernel is booting fine and the problem is when it tries to process my initrd.

I would be very gratefull for any advice, even for example how to get more info about the error - the "domain 0 crashed" is not very helpful for me. Many thanks!
