If I use device_model = 'qemu-dm', I need to use vcpus=1. Using vcpus=2 will
cause Win XP Home domU to crash. The situation is reversed.

Hi,
I changed to using device_model = 'qemu-dm' but it still doesn't work.
Here is my Win XP Home HVM Dom U configuration:
import os, re
arch = os.uname()[4]
if re.search('64', arch):
arch_libdir = 'lib64'
else:
arch_libdir = 'lib'
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 2048
# Should be at least 2KB per MB of domain memory, plus a few MB per
vcpu.
shadow_memory = 8
name = "winxphome32"
vif = [ 'bridge=eth0' ]
acpi = 1
apic = 1
disk = [ 'phy:/dev/virtualmachines/winxphome32,hda,w',
'phy:/dev/sr0,hdc:cdrom,r' ]
#device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
#device_model = '/usr/' + 'lib' + '/xen/bin/qemu-dm'
device_model = 'qemu-dm'
#-----------------------------------------------------------------------
------
# boot on floppy (a), hard disk (c) or CD-ROM (d)
# default: hard disk, cd-rom, floppy
boot="cd"
sdl=0
vnc=1
vncconsole=1
vncpasswd=''
serial='pty'
usbdevice='tablet'
pci = [ '01:00.0' ]
vcpus=1
gfx_passthru=2

I suspect you are using old hvm config file. The device_model is
changes in config file.
in old config file:
# New stuff
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
in new config file:
# Device Model to be used
device_model = 'qemu-dm'
Pls check it, and use the latest config file to create guest.

Subject: [Xen-devel] xen-unstable pci passthrough
I have not been able to passthrough any PCI devices using the
latest xen-unstable. I have a DQ45CB, and have successfully passed
devices to guests using 3.4.1.
The latest c/s in my copy of xen-unstable is 20145. I just
started playing around with unstable yesterday, so I can’t tell you if
earlier revisions worked. I’ve tried with various dom0 kernels, the
current 2.6.18.8-xen branch, a xenified 2.6.29.6, and a pvops
2.6.31-rc6, and in every case I get the same error. I’ve tried both
putting pci= in the config file, and hot-adding the device using xm
pci-attach. In every case, the xm command (either create or pci-attach)
fails with the message “Error: Timed out waiting for device model
action”. The guests in every case are HVM guests, some flavors of
Windows, as well as the Knoppix 5.3.1 DVD.
The relevant xm dmesg output is:
(XEN) PCI add device 00:1b.0
(XEN) [VT-D]iommu.c:1292:d0 domain_context_unmap:PCIe: bdf =
0:1b.0
(XEN) [VT-D]iommu.c:1178:d0 domain_context_mapping:PCIe: bdf =
0:1b.0
(XEN) [VT-D]io.c:284:d0 VT-d irq bind: m_irq = 37 device = 3
intx = 0
(XEN) [VT-D]iommu.c:1292:d0 domain_context_unmap:PCIe: bdf =
0:1b.0
(XEN) [VT-D]iommu.c:1178:d0 domain_context_mapping:PCIe: bdf =
0:1b.0
And the messages from qemu-log:
dm-command: hot insert pass-through pci dev
hot add pci slot -2 exceed.
Please let me know what else I need to supply to help resolve
this problem. If I need to enable debugging messages, let me know the
best way to do this.
