Previously, by default we would install our python modules into
/usr/lib/python/xen, for example /usr/lib/python/xen/__init__.py.
Upstream python's standard install location (a) includes the Python
version number and (b) puts things in site-packages by default.
Our best conjecture for the reason for this was an attempt to make the
installs portable between different python versions. However, that
doesn't work because compiled python modules (.pyc), and C python
extensions corresponding to one version of python, are not compatible
across different versions of python.
This is why upstream include the version number.
site-packages is the standard location for locally-installed packages
and is automatically included on the python search path.
In this change, we abandon our own unusual python path setup:
* Invoke setup.py in an entirely standard manner. We pass
PREFIX and DESTDIR using the appropriate options provided by
setup.py for those purposes (adding them to setup.py calls
which were previously lacking them).
* Since the installation locations are now on the standard
python path, we no longer need to add anything to the path
in any of our python utilities. Therefore remove all that
code from every python script. (Many of these scripts
unconditionally added /usr/lib/python and /usr/lib64/python which
is wrong even in the old world.)
* There is no longer any special `Xen python path'. xen-python-path
is no longer needed. It is no longer called by anything in our
tree. However since out-of-tree callers may still invoke it, we
retain it. It now prints a fixed string referring to a directory
which does not to exist; callers (who use it to augment their
python path) will thus add a nonexistent directory to their python
path which is harmless.
* Remove various workarounds including use of setup.py --home
(which is intended for something completely different).
* Remove tests for the XEN_PYTHON_NATIVE_INSTALL build-time
environment variable. The new behaviour is the behaviour which we
should have had if this variable had been set. That is, it is now
as if this variable was always set but also bugs in the resulting
install have been fixed.
This should be a proper fix for the bug addressed by c/s 19515.

When xend calls xc.test_assign_device, xend does not have to give
the domain-ID of a guest domain.
This patch gives domain-ID 0 to xc.test_assign_device.
The following methods give domain-ID 0 to xc.test_assign_device
currently.
- setupDevice@xend/server/pciif.py
- pciinfo@xend/XendNode.py

The current parser only accepts vslots 0 - f (hex), that is, only

with a leading 0 or 1 are also valid, representing the

I started a VM by using xm create, then I checked values of VDI

"r" "w" "w!"
VDI:read_only True True True <-- Always True!
VDI:sharable True True True <-- Always True!
VBD:mode RO RW RO
^^ <-- It should be RW.
This patch fixes the values of the records as follows.

The current implementation of 'xm pci-list-assignable-devices' command
has a problem that it directly invokes hypercall using
xen.lowlevel.xc.
This is probably based on an assumption that the command is executed
on the host itself, but in fact there are cases xm commands can be
executed on a remote server through xmlrpc.
So this patch makes the xm command just inquire of xend about the
information of available devices.

Currently a slot may be specified for a hot-plug device,
but not for a pass-through device that is inserted at boot time.
This patch adds support for the latter.
The syntax is:
BUS:DEV.FUNC[@VSLOT]
e.g: 0000:00:1d:0@7
This may be important as recent changes that allow any free PCI
slot to be used for pass-through (and hotplug) may case pass-through
devices to be assigned in different locations to before. Amongst
other things, specifying the slot will allow users to move them
back, if there is a need.
