Add commands to automatically prep devices for pass-through The current method for passing through devices requires users to either modify cryptic Linux boot parameters and reboot, or do a lot of manual reads and writes into sysfs nodes. This set of patches introduces commands to make this easier. It expands on the concept of "assignable" (from the list_assignable_devices command).

...PCI devices with stubdomains Since 23565:72eafe80ebc1 the xenstore entries for the stubdomain''s PCI were never created and therefore the stubdom ends up waiting forever for the devices which it has been asked to insert to show up. Since the stubdomain is already running when we call the libxl_device_pci_add loop in do_domain_create we should treat it as if "starting == 0".

...o-generated and special hooks are declared and stubbed where, for example, conversion between libxl_file_reference and a python file object is required. There are minor changes to libxltypes.py and the libxl.idl file and the new rules are documented. I have also removed the use of a nasty union in libxl_device_pci structure which was making the binding more complicated than necessary and for no good reason (exporting random bits of low level ABI that libxl would rather hide anyway). Finally there is a corresponding (untested) change to the ocaml binding to fix a compile error and maintain previous API in oca...

The following series implements libxl_domain_config_init as per the libxl API requirement that each type has an init function. The first function does this in an open coded manner and is proposed for Xen 4.2. The second function is RFC only since it moves the definition of this type into the IDL and makes the required infrastructure updates to enable this. I think this is more 4.3 material at

The series introduces auto-generation of the type definitions used in the libxl interface followed by auto-generation of a destructor function for each type. In the future it may be possible to use the related data structures for other purposes, for example auto-generation of the functions to marshal between C and language binding data types. tools/_libxl_types.h should be identical both before

The following series of patches fill in most of the gaps in the OCaml bindings to libxl, to make them useful for clients such as xapi/xenopsd (from XCP). There are a number of bugfixes to the existing bindings as well. I have an experimental version of xenopsd that successfully uses the new bindings. An earlier version of the first half of the series was submitted to the last by Ian Campbell on
