Sure. Thanks again for the prompt help - very appreciated.

As I see I am trying to do what only few have done wrt Xen dom0 to package as bootable iso with ramdisk.

Now error below Xen dom 0 is trying to bring up Linux:

<..clipped..>

md: ... autorun DONE.

RAMDISK: ext2 filesystem found at block 0

RAMDISK: image too big! (524288KiB/4096KiB)

<...clipped: Details below...>

The grub is:
