xpci —
xpci* at xenbus?
pci* at xpci?
xpci driver is the frontend part of the PCI
  pass-through functionality that can be used by Xen guest domains to
  communicate with PCI devices.
From a guest point of view, xpci is
    similar to a pci(4) bus, except
    that the guest talks with the PCI backend driver instead of the real
    physical device directly.
When the host domain is NetBSD, the
    xpci driver is backed by a
    pciback(4) driver within the
    dom0.
xpci driver first appeared in
  NetBSD 5.1.
xpci driver was written by Manuel
  Bouyer
