[Xen-users] Problem with HVM domU and virtual disk image

Hello,

I''m trying to create a HVM machine with a Virtual Disk Image (created
using dd if=/dev/zero of=virtualdisk-root.img bs=1k seek=2048k
count=1) and attach it to a HVM domU using the following template:

#  -*- mode: python; -*-

import os, re

arch_libdir = ''lib''
arch = os.uname()[4]
if os.uname()[0] == ''Linux'' and
re.search(''64'', arch):
    arch_libdir = ''lib64''

kernel = "/usr/lib/xen/boot/hvmloader"

builder=''hvm''

memory = 1024

name = "Ubuntu11"

vcpus=1

vif = [ ''type=ioemu, bridge=eth1'' ]

disk = [ ''file:/home/xen/ubuntu-server.img,sda,w'',
''file:/home/xen/ubuntu.iso,hdc:cdrom,w'' ]
# I have to use sda because if I put hda the installer doesn''t find the
disk

device_model = ''/usr/'' + arch_libdir +
''/xen/bin/qemu-dm''

boot="dc"

vnc=1
vnclisten="0.0.0.0"
vncpasswd=''XXXX''

serial=''pty''

localtime=1
usb=1
usbdevice=''tablet''
keymap=''es''

With this template I''m able to install the system to the disk, the
problem comes when I later on remove the CDROM (hdc) and try to boot
from sda. If I change the disk line to:

disk = [ ''file:/home/xen/ubuntu-server.img,sda,w'' ]

The domU starts and closes, almost immediately. This is what xend says:

If I replace sda with hda the domU boots the kernel, but cannot find
root disk and drops to initramfs, if I take a look at the devices in
/dev, there doesn''t seem to be any kind of Disk (no hda, sda, or
xvda). Can someone give a hand with this? I''ve been struggling with
this issue for some time, and I cannot seem to be able to figure out
how to solve it.

Thanks and regards, Roger.

[Xen-users] Re: Problem with HVM domU and virtual disk image

Just as a note in case someone comes up with the same issue, don’t try
to install Ubuntu as HVM (11.04 amd64), it will fail to recognize the
hard disk and network card (at least in my case), I’ve lost almost a
week thinking it was a problem with Xen, and it turned out to be a
Ubuntu specific issue. Debian and FreeBSD work well under HVM.

Nod, I saw the same thing, and I hope they fix it in the next release. 
To work around it, you have to disable at least ACPI and possibly APIC, 
and set xen_platform_pci = 0 in the domU cfg. There''s also some
trickery
that must be done during the install process to kill hung processes. All 
in all, it''s a painful experience.

Debian Squeeze also doesn''t install perfectly under HVM, IIRC, but just
due to a glitch in the installer, and everything works fine after it''s 
set up.

Re: [Xen-users] Re: Problem with HVM domU and virtual disk image

Hello,

Debian Squeeze 6.0.1a worked perfectly for me. Regarding the
submission of bugs, I would like to extract the kernel log from the
Ubuntu HVM (because I can boot to the LiveCD), but since I have no
network or hard drive this is kind of complicated. I will try to
attach a USB drive or something, so I can make a dump there.
Suggestions about how to save this trace are welcome.

Regards, Roger.

Re: [Xen-users] Re: Problem with HVM domU and virtual disk image

I would like to refine the statement made before about Debian 6.0.1a,
it works well under HVM on 4.0, but fails to detect hard drive on
4.1.1 during the instal, and I think it''s because it tries to load the
PV drivers.
