GPLPV depends on KMDF (Kernel Mode Driver Framework). If there is no
KMDF currently installed then it is installed along with the drivers and
everything will be active on the next boot. If the same or newer KMDF is
already installed then the drivers are installed and everything will be
active on the next boot. If an older version is installed then it will
be upgraded but the drivers won't load until the new KMDF is loaded.
When the new KMDF is loaded on the next boot, the drivers load but too
late in the boot process so it's only on the next boot that they can
properly take control.

What you're seeing is almost the opposite of this though... when you
first install, does xenpci load (the unknown PCI device should be gone
and replaced with xenpci and have not exclamation marks etc)? Do any of
the other devices load (xenvbd/xenpci/xenusb/xenscsi etc)? What about on
the first reboot?
