You probably want root_args set to "ro", otherwise fsck will
complain.

Assuming you've installed hda6 with a standard linux
installation, you probably don't want to explicit set the init
program, or the run level

e.g. <args>DOMID=+</args>

> <nw_ip>=+</nw_ip>

This will set the IP address to dom0's IP address plus the
current domainID. You might want to set this to a fixed value.

I don't like the look of this last line -- its definitely the
primary cause of your problems.

What version of Xen/Xenolinux are you using? What's the contents of
/proc/xeno/blkdev_info ?

Best,
Ian
