Hi,

Instead of GPLPV driver or spice-guest-tools-0.2.exe,  I use es1370 driver
to help to finish the installation automatically.

My config file is as below:

# =====================================================================
# Example HVM guest configuration
# =====================================================================
#
# This is a fairly minimal example of what is required for an
# HVM guest. For a more complete guide see xl.cfg(5)

# This configures an HVM rather than PV guest
builder = "hvm"

# Guest name
name = "win7"

device_model_version ="qemu-xen"
device_model_override="/usr/lib/xen/bin/qemu-system-i386"

# 128-bit UUID for the domain as a hexadecimal number.
# Use "uuidgen" to generate one if required.
# The default behavior is to generate a new UUID each time the guest is
started.
#uuid = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"

# Enable Microsoft Hyper-V compatibile paravirtualisation /
# enlightenment interfaces. Turning this on can improve Windows guest
# performance and is therefore recommended
#viridian = 1

# Initial memory allocation (MB)
memory = 1024

# Maximum memory (MB)
# If this is greater than `memory' then the slack will start ballooned
# (this assumes guest kernel support for ballooning)
#maxmem = 512

# Number of VCPUS
vcpus = 2

# Network devices
# A list of 'vifspec' entries as described in
# docs/misc/xl-network-configuration.markdown
vif = [ 'type=ioemu, mac=00:16:3E:*:*:*,bridge=br0']

# Disk Devices
# A list of `diskspec' entries as described in
# docs/misc/xl-disk-configuration.txt
disk = [ '/root/win7.img,raw,hda,rw' ]

# Guest VGA console configuration, either SDL or VNC
sdl = 0
#vnc = 1
#vnclisten="0.0.0.0"
