[Xen-users] Can't boot HVM Linux guests on Debian Squeeze Dom0

[Garrett Robinson <Garrett.Robinson@xxxxxxxxxxx>]

I just downloaded Debian Squeeze and installed Xen from packages, following the instructions here: http://wiki.debian.org/Xen

I am able to get PV guests up and running easily, but HVM guests will not even boot.

The HVM I am currently trying to run is Debian sarge, which I installed into a disk image and configured using qemu.

I am running on an HP Proliant ML150G6, which has Intel-VT hardware virtualization. One strange thing that I noticed is both

grep vmx /proc/cpuinfo

grep svm /proc/cpuinfo

return nothing, although according to the BIOS settings the Intel-VT extensions are enabled.

On trying to boot my HVM guest (xm create sarge.cfg), several different things would happen. At I fiddled with the configuration file for the VM a bit in attempts to get things working, it seems to have settled on the following. It prints

Using config file "./sarge.cfg"

and then hangs for a looong time, at least one minute. After waiting a bit, it prints 

Error: Domain 'sarge' does not exist.

and quits.

I would really appreciate any advice or insight into this problem and possible solutions! I am including the configuration file for the VM in question, please let me know if more information would be useful:

import os, re

arch = os.uname()[4]

if re.search('64', arch):

        arch_libdir = 'lib64'

else:

        arch_libdir = 'lib'

device_model = '/usr/' + arch_libdir + '/xen-4.0/bin/qemu-dm'

name = 'sarge'

kernel = '/usr/lib/xen-default/boot/hvmloader'

builder = 'hvm'

memory = 256

shadow_memory = 16

vcpus = 1

disk = [

'file:/root/sarge.img,hda1,w'

 ]

vif = [ 'type=ioemu, bridge=xenbr0' ]

vnc=1

vncunused=1

stdvga=0

serial='pty'
