the only place i'm seeing details about backend drivers activity is standard
syslog output (/var/log/messages). i guess the domU creation at dom0 side goes
as follows:
* xm/xend (or xl/libxl - i did not migrate to one yet) queries xenstore for
resources the domU is being assigned with
* if xenstore succeeds with the inquiry it marks the resource as allocated and
posts subsequent inquiry to dom0 kernel as a holder of all backend xen
resources
* the kernel performs particular resource initialization and generates an
appropriate event
* the event is handled by udev (/etc/udev/rules.d/xen-backend.rules)
* udev processes a matching rule and calls userspace script (vif-setup for
network backends and vscsi for block backends) attaching the resource to the
domU being started. i believe all possible debugging should deal with these
scripts
my second guess is that real hardware passthrough works indentically
i just uploaded everything related to a pure pv domU creation:

your configuration
