[Xen-devel] [PATCH] Support user domain create extensions

[Juergen Gross <juergen.gross@xxxxxxxxxxxxxx>]

This patch supports arbitrary extensions to xl create by being able to specify
a script which is run at domain creation. The script is specified in the xl
config file and will be started at domain creation with following parameters:

<script> restore|create <domid> <path of config file>

To be able to use non-standard devices a new device class "NSTD" is defined.
The xl framework will remove all NSTD devices when destroying a domain.

This extension enables us (Fujitsu) to use standard Xen with xl for our
Xen-based mainframe with BS2000 as DomU (this requires an additional Xen
PV-device emulating the BS2000 I/O-system).

It might be interesting for others as well to be able to add new experimental
devices or other features to Xen without having to change Xen (especially xl)
itself.
