It comes from pygrub itself which is being run early on in the domain
construction process.

No, it appears it isn't even finding the partition which should contain
it.

If you run "pygrub /path/to/disk.img" I expect it will report the same,
but can you please confirm.

It would also be useful to see the full logs from "xl -vvv
create /vm/arch1/arch1.conf".

These are in the guest? I don't think it is getting near to consulting
these.

What does the partition table of your disk image look like? (You
provided a bunch of gdisk runes earlier, but I've no idea what they
would result in.
