compiles and didn't immediately explode as soon as I started a VM.
I've not given it much testing beyond that, though.

In some configurations, when dom0 is busy with I/O, it may take
several minutes to complete all hotplug scripts required when a new
domain is being created. As device create timeout is set to 100
seconds, users get "hotplug scripts not working" error instead of a
new domain.
This patch makes both DEVICE_CREATE_TIMEOUT and DEVICE_DESTROY_TIMEOUT
configurable in xend-config.sxp to allow users to easily adapt hotplug
timeouts to their environment.

In the case of inactive managed domains:
The following error occurs currently. We cannot change the
configuration of the VBD by using xm block-configure. Of course,
using xm block-detach and xm block-attach instead of xm
block-configure, we can change it. However, I'd like to change it by
using xm block-configure.
In the case of active domains:
Another problem occurs after a domain was rebooted. Even if we
change a configuration of a VBD in the domain by using xm
block-configure, the configuration of the VBD is reverted to previous
configuration after the domain was rebooted.

When a PCI function is passed-through extra options may be passed
through.
In the case of boot-time PCI pass-through the documented format is:
[dom:]bus:dev.slot[@vslot][[,opt]...]
e.g.
00:01.00.1@7,msitranslate=3D1
In the case of PCI hot-plug the xm pci-attach command take the
following arguments:
[-o opt[,opt]...] [dom:]bus:dev.slot [vslot]
e.g.
-o msitranslate=3D1 00:01.00.1 7
These xm ends up passing these to xem-qemu as:
[dom:]bus:dev.slot[[,opt]...][@vslot]
e.g.
00:01.00.1,msitranslate=3D1@7
Note that the option and the vslot have are transposed when
compared to the format used by boot-time PCI pass-through.
The parser inside qemu-xen can only handle the format used by
boot-time PCI pass-through and because of this ignores
any options passed by hot-plug.
This patch alters format used by hot-plug to match the parser.

We change all invocations of setup.py as follows:
* use $(PYTHON) instead of `python' so that the user can specify
an alternative python version if they need to. If not set it
defaults to `python' in Config.mk.
* pass --prefix=$(PREFIX) via a new make variable
$(PYTHON_PREFIX_ARG). This allows a user to suppress the
--prefix=... argument entirely by setting PYTHON_PREFIX_ARG=''.
This will work around the bug described here
https://bugs.launchpad.net/ubuntu/+bug/362570
where passing --prefix=/usr/local (which ought to have no effect as
/usr/local is the default prefix) changes which subdirectory
distutils chooses, and results in the files being installed in
site-packages which is not on the default search path.
Users not affected by this python packaging bug should not set
PYTHON_PREFIX_ARG and their builds will not be affected. (Provided
PREFIX did not contain spaces. People who put spaces in PREFIX are
being quite optimistic.)

op_pincpu method in SrvDomain.py does not currently work because
op_pincpu method gives string objects to a cpumap argument of
domain_pincpu method in XendDomain.py though the cpumap argument
expects list objects.
This patch solves the above problem as follows.
op_pincpu method gives string objects to the cpumap argument as is,
because op_pincpu method cannot give list objects to the cpumap
argument.
Instead, domain_pincpu method expects that the cpumap argument is
string objects, then domain_pincpu method converts the cpumap
argument into list objects.
Also, the patch modifies two methods (except for op_pincpu method)
calling domain_pincpu method. The methods give string objects to
the cpumap argument instead of list objects.
