[win-pv-devel] No matching device was found when trying to install PV drivers

[Nick Craig-Wood <nick@xxxxxxxxxxxxxx>]

We've been trying to make the new PV drivers work under Xen 4.6.3
(compiled from source) with Windows 2012R2

When we try to install them the drivers can't find the device they are
supposed to be attached to.  The Xen platform PCI device is visible in
device manager.

This is trying with the 8.1 Release.

The xen config looks like this - note the use of stubdomains.

memory = 4096
maxmem = 4096
name = "win2012r2"
domain = "win2012r2"
vif = [ 'ip=1.2.3.4, mac=00:16:3E:00:00:01, vifname=win2012r2, type=vif,
script=/etc/xen/scripts/vif-route' ]
disk = [ 'format=raw, vdev=hda, access=rw,
target=/dev/lvm/win2012r2_root_fs' ]
restart = 'onreboot'
vcpus = 4
cpu_weight=1024
# enable stubdomain
device_model_stubdomain_override = 1
# enable pv on hvm
xen_platform_pci=1
# HVM options
builder='hvm'
monitor_path = 'null'
boot='c'
sdl=0
vnc=1
vncunused=0
vnclisten='0.0.0.0'
vncdisplay='XXXX'
vncpasswd='XXXXXXXX'
serial='pty'
parallel='none'
ne2000=0
usb=1
usbdevice='tablet'

The config works fine for Linux HVM with PV.

Any help much appreciated, and apologies in advance if this is a stupid
question!

Thanks

Nick
