Xen users - Sep 2007 - Domain has shutdown: reason=poweroff

Hi list,

This is probably a familiar problem, but I haven''t found anything in
the
archives yet.

I am trying to start hvm domU, but as soon as the domU unpauses after
waiting for devices, it immediately does a shutdown.
I am clearly doing something wrong.  I''m guessing xend can''t
find a
boot image? don''t know.  

xend.log:
[cut]

This is on xen 3.0.4, SuSE sles10 sp1.  domU is sles9 x86-64.  hardware
is AMD Opteron 2220 (Sun x4200)


Here is my domU config:
# Host tenar-vhost

import os, re
arch = os.uname()[4]
if re.search(''64'', arch):
    arch_libdir = ''lib64''
else:
    arch_libdir = ''lib''

localtime = 0
on_poweroff = ''destroy''
on_reboot = ''restart''
on_crash = ''restart''

name = ''tenar-vhost''
memory = 2048
vcpus = 4

builder = ''hvm''
vif = [ ''type=ioemu, model=rtl8139, mac=00:16:3e:bc:5D:4B,
bridge=xenbr0'' ]
kernel = "/usr/lib/xen/boot/hvmloader"
device_model = ''/usr/'' + arch_libdir +
''/xen/bin/qemu-dm''
boot="cda"
# set runlevel here
extra = '' ''

disk = [
''phy:data0/tenar-vhost-root, ioemu:sda1,w'', 
''phy:data0/tenar-vhost-swap, ioemu:sda2,w''
]

serial="pty"
nographic=1

AFAIK hvm only takes complete discs here, and the sda looks bad.
Try something like

disk = [ ''phy:/dev/data0/tenar-vhost-root,hda,w''	]

Thanks for your reply.  I tried your suggestion, but I think my syntax
error is only part of the problem.  But it points out my confussion
about use of ''phy'' disks when building hmv.  I dont understand
the
boot process of hvmloader.  Under pv I would create a logical volume
for each partition and copy my OS into them with no regard to grub
and boot loading.

Do I need to install grub on the logical volume data0/tenar-vhost-root?
Do I need to make a partition table also?
How is this done for real disk volumes as opposed to disk image files?
