Re: Installing a NetBSD DomU on a file-backed disk

[Blair Sadewitz <blair.sadewitz%gmail.com@localhost>]

OK, it's working.  I shouldn't have bothered using sysinst to begin
with, as I think it was easier just doing it myself in this case.  I
kept everything very simple to eliminate points of failure.  Labelling
the disk didn't break anything.  Of course, I didn't install the
bootblocks! ;-)

My disklabel:

type: unknown
disk: Xen Virtual ESD
label:
flags:
bytes/sector: 512
sectors/track: 2048
tracks/cylinder: 1
sectors/cylinder: 2048

headswitch: 0           # microseconds
track-to-track seek: 0  # microseconds

16 partitions:

This is my /boot/grub/menu.lst and /boot/grub/grub.conf:

default=0
timeout=10
title NetBSD (comment)
  root (hd0)
  kernel /netbsd root=xbd0

(I don't know which one it looks for, or if it looks for both, or
what; I'll figure that out later)

I'm swapping to a file.  If I do this again, I'll experiment more, but
for now I just wanted a working system.

Oh, FWIW, I get this in my message buffer:

xbd0: WARNING: cache flush not supported by backend

How do I, um, get them to support it?  I don't like that.
