We have some code in our tree to support pci passthrough of intel

This patch moves igd-passthrough-isa-bridge creation out of the xen
passthrough code into machine init. It is triggered by the
igd-passthru=on machine option. Advantages:
* This works for on both xen and kvm.
* It is activated for the pc machine type only, q35 has a real

The xenstore-ls output is not complete. Could you please send it again?
I noticed from the DomU config file that it is not a Windows VM, as
previously discussed, but a Linux VM. That is OK, but of course in that
case you won't be able to use the Windows PV drivers which I linked.

There are a few issues in the config files. In conf_DomU_WindowsHVM:
- device_model is set to /usr/lib64/xen/bin/qemu-dm, which is the old
qemu-xen-traditional device model, known to have worse disk

objections, please let us know.
