We have defaulted to using the system libaio for a while now and I din't think
there are any relevant distros which don't have it that running Xen 4.4 would
be reasonable on.
Also it has caused confusion because it is not ever wanted on ARM, but the
build system doesn't express that (could be fixed, but deleting is the right
thing to do anyway).

Updated the figlet version number to "Xen 4.3-rc". Also remove the

It is sometimes hard to discover all the optional tools that should be
on a system to build all available Xen documentation. By checking for
documentation generation tools at ./configure time and displaying a
warning, Xen packagers will more easily learn about new optional build
dependencies, like markdown, when they are introduced.
Based on a patch by Matt Wilson. Changed to use a separate
docs/configure which is called from the top-level in the same manner
as stubdoms.
Rerun autogen.sh and "git add docs/configure" after applying this patch.

Hotplug has been replaced by udev since several years. Remove the
hotplug related files and install udev unconditionally.
This makes it possible to remove udev from rpm BuildRequires which
reduces the buildtime dependency chain. For openSuSE:Factory it was
done just now:

The patch by itself will have no practical impact unless someone

Added autotools magic to replace custom check scripts. The previous
checks have been ported to autoconf, and some additional ones have
been added (plus the suggestions from running autoscan). Two files are
created as a result from executing configure script, config/Tools.mk
and config.h.
conf/Tools.mk is included by tools/Rules.mk, and contains most of the
options previously defined in .config, that can now be set passing
parameters or defining environment variables when executing configure
script.
config.h is only used by libxl/xl to detect yajl_version.h.
[ tools/config.sub and config.guess copied from
autotools-dev 20100122.1 from Debian squeeze i386,
which is GPLv2.
tools/configure generated using the included ./autogen.sh
which ran autoconf 2.67-2 from Debian squeeze i386. autoconf
is GPLv3+ but has a special exception for the autoconf output;
this exception applies to us and exempts us from complying
with GPLv3+ for configure, which is good as Xen is GPL2 only.

I have confirmed that the relevant pages have been transitioned.
What remains is pages which have not yet been moved over:
$ rgrep xenwiki *

tools/xenballoon/xenballoond.README:http://wiki.xensource.com/xenwiki/Open_Topics_For_Discussion?action=AttachFile&do=get&target=Memory+Overcommit.pdf
Note that "PythonInXlConfig" never existed in the old wiki and does not exist
in the new. This reference was introduced by 22735:cb94dbe20f97 and was
supposed to have been written prior to the 4.1 release. I have transitioned it
anyway but it's not clear how valuable the message actually is. Perhaps we
should just remove that aspect of it?

I could have sworn I did this years ago.
IIRC the need for our own copy was due to the use of io_set_eventfd which is
not present in version 0.3.106. However it is in 0.3.107 the first version of
which was uploaded to Debian in June 2008 (I can't find a better reference for
the release date).
The necessary version is available in Debian Lenny onwards and is in at least
RHEL 6, Fedora 13 and OpenSuSE 11.3. The necessary version appears to not be
available in RHEL 5 or SLES 11 which is why I haven't simply nuked the in tree
version.
This is based on tools-system-libaio.diff from the Debian packaging although I
have made it optional (but default on).

Cloning and building a kernel as part of the Xen distribution
implicitly advises that this kernel is the best kernel for all users
and many users appear to be under this impression, even though there
is no fundamental coupling between the Xen distribution and a
particular domain 0 kernel.
There are several choices available for domain 0 kernel, as well as
other user specific variations in requirements e.g. for kernel
configurations. It's not clear that whatever the xen build system
happens to produce (which is really tailored to the needs of the
automated build system) is best for anybody.
Coupling the kernel build with the Xen build has proved problematic
for stable Xen releases as it implicitly blesses the particular kernel
(at a particular point in time) as a constituent part of the Xen
release, while in reality the OS kernels are separate entities with
their own release cycles which may or may not coincide with the
maintenance of Xen stable branches.
Therefore disable the building of a kernel as part of the Xen
distribution by default and instead direct users to use an OS
distribution provided kernel (properly packaged with security updates
via the normal distribution mechanisms etc) where possible and give
pointers to suitable resources providing guidance for cases where it
is not.
This decouples the implicit advice as to the best kernel at any moment
from Xen's own release cycle and removes the implicit suggestion that
only particular domain 0 kernel will do.
The actual infrastructure is left in place since the automated test
system (currently) relies on it (but always asks for the specific
kernel variant it wants for a particular test).
(I also tried to remove Linux-isms from the README's Quick start
guide. In particular I'm not sure what was supposedly Linux specific
about steps 3 and 4 therefore I have removed the suggestion that they
are.)

This provides a replacement config file parser for "xl" based on bison
and flex.
Benefits:
* proper error reporting with line numbers
* parser can understand nearly all "xm" configuration files directly
(doesn't understand Python code but should do everything else)
* parser also understands the ;-infested "xl" style files
* removes the dependency on libconfig
* better checking for certain kinds of mistakes
* eliminates the strange "massage file and try again" code
This is intended to support all config files currently supported by
"xl" and almost all files supported by "xm". (NB that whether a
feature works depends on the implementation of that feature in
xl/libxl of course.)
This patch also introduces a new library "libxlutil" which is mainly
for the benefit of "xl". Users of libxl do not need to use libxlutil,
but they can do so if they want to parse "xl" files without being
"xl".
