The current usage of LIBEXEC is bogus. It describes the directory for
private xen executables. Other places create their own, similar
libexecdir path as $prefix/lib/xen/*.
Additional two other variables are used to describe similar paths:
PRIVATE_BINDIR and PRIVATE_PREFIX
The autoconf documentation refers to libexec as a directory for
executables and stuff which is called by other programs, not by the
user.
Adjust all places that want libexecdir as a target path. LIBEXEC refers
now to the base directory. Three convenience variables are used to refer
to paths to private binaries, libs and include files.
In the systemd files LIBEXEC_BIN is substituted, so this variable has to
be present in autoconf. All other variables are expanded in Paths.mk
because they are only used in Makefiles.
Most users of LIBEXEC are updated to use LIBEXEC_BIN because that is
what they want.
Users of PRIVATE_BINDIR are updated to use LIBEXEC_BIN because that is
what they want. PRIVATE_BINDIR and PRIVATE_PREFIX usage is removed by
this patch, in favour of LIBXEC_BIN and LIBEXEC
An internal libxl function was removed. A single helper to retrieve
LIBEXEC_BIN remains.
As suggested by the autoconf documentation, configure appends the
package name to LIBEXEC to make sure the provided directory really
refers to xen. This makes sure "make uninstall" preserves the real
libexecdir.

`xenpvnetboot' supports getting boot images from following locations:
- http://host/path
- https://host/path
- ftp://host/path
- file:///path
- tftp://host/path
- nfs:host:/path
- /path
- /path/file.iso
- /path/filesystem.img
- /dev/sda1
- nfs+iso:host:/path/file.iso
- nfs+iso:host:/path/filesystem.img
To use it, make `xenpvnetboot' as bootloader for PV guest::
bootloader = '/usr/bin/xenpvnetboot'
To get boot images from various locations, set the right bootloader
arguments, e.g.:
bootloarder_args = ['--location=http://192.168.0.1/fedora/x86_64']
bootloarder_args = ['--location=ftp://192.168.0.1/fedora/x86_64']
bootloarder_args = ['--location=file:///fedora/x86_64']
bootloarder_args = ['--location=tftp://192.168.0.1/fedora/x86_64']
bootloarder_args = ['--location=/fedora/x86_64']
bootloarder_args = ['--location=/fedora/Fedora-16-x86_64-DVD.iso']
bootloarder_args = ['--location=nfs:192.168.0.1:/fedora/x86_64']
bootloarder_args = ['--location=nfs+iso:192.168.0.1:/fedora/Fedora-16-x86_64-DVD.iso']
You can use `kernel' and `ramdisk' to specify the relative path of
boot kernel and ramdisk. `xenpvnetboot' will join them with the
location to find the boot kernel and ramdisk, e.g.:
kernel = 'images/pxeboot/vmlinuz'
ramdisk = 'images/pxeboot/initrd.img'
bootloarder_args = ['--location=http://192.168.0.1/fedora/x86_64']
kernel = 'fedora/x86_64/images/pxeboot/vmlinuz'
ramdisk = 'fedora/x86_64/images/pxeboot/initrd.img'
bootloarder_args = ['--location=http://192.168.0.1/']
You can also omit the `--location' option and specify the full URL for
`kernel' and `ramdisk' directly, e.g.:
kernel = 'http://192.168.0.1/fedora/x86_64/images/pxeboot/vmlinuz'
ramdisk = 'http://192.168.0.1/fedora/x86_64/images/pxeboot/initrd.img'
If only `--location' is specified and `kernel' and `ramdisk' are not
specified, `xenpvnetboot' will search the following places for boot
images from the location::
('images/xen/vmlinuz', 'images/xen/initrd.img'), # Fedora <= 10 and OL = 5
('boot/i386/vmlinuz-xen', 'boot/i386/initrd-xen'), # openSUSE >= 10.2 and SLES >= 10
('boot/x86_64/vmlinuz-xen', 'boot/x86_64/initrd-xen'), # openSUSE >= 10.2 and SLES >= 10
('current/images/netboot/xen/vmlinuz', 'current/images/netboot/xen/initrd.gz'), # Debian
('images/pxeboot/vmlinuz', 'images/pxeboot/initrd.img'), # Fedora >=10 and OL >= 6
('isolinux/vmlinuz', 'isolinux/initrd.img'), # Fedora >= 10 and OL >= 6
`xenpvnetboot' requires python module `urlgrabber'
http://urlgrabber.baseurl.org/.

Create two new variables called APPEND_ and PREPEND_ to add compile
flags at the beginning or at the end of the search path.
Added a new semantic for user defined compile flags, here is the list
of possible options:
PREPEND_LIB: add libraries to the search path before xen
(before xen installation folders).
PREPEND_INCLUDES: add headers to the search path before xen
(before xen installation folders).
APPEND_LIB: add libraries to the search path at the end
(after all xen installation folders have been added).
APPEND_INCLUDES: add libraries to the search path at the end
(after all xen installation folders have been added).
EXTRA_INCLUDES and EXTRA_LIB can still be used, and they will have the
same effect as PREPEND_INCLUDES and PREPEND_LIB.

A fair few things under tools link against libraries which they don't
even use.
Most of this appears to come from copy-and-pasting previous Makefile
snippets and cargo-culting plus the tendency to define global $(LIBS)
even for Makefiles which build multiple separate utilities or
libraries.
Identified by comparing a build with --as-needed to one without by

to crash the guest (since the CPUs may not be executing in kernel

pygrub currently has a hardcoded path of /usr/bin/python which is not
correct if the version of python at install time is not the same as
that at build time. This patch uses the existing install-wrap and
python/get-path machinery.
(It does not address the currently-existing bug that the get-path
machinery works by assuming that `python' is a symlink, rather than
querying the python interpreter for its version.)

Tmem, when called from a tmem-capable (paravirtualized) guest, makes
use of otherwise unutilized ("fallow") memory to create and manage
pools of pages that can be accessed from the guest either as
"ephemeral" pages or as "persistent" pages. In either case, the pages
are not directly addressible by the guest, only copied to and fro via
the tmem interface. Ephemeral pages are a nice place for a guest to
put recently evicted clean pages that it might need again; these pages
can be reclaimed synchronously by Xen for other guests or other uses.
Persistent pages are a nice place for a guest to put "swap" pages to
avoid sending them to disk. These pages retain data as long as the
guest lives, but count against the guest memory allocation.
Tmem pages may optionally be compressed and, in certain cases, can be
shared between guests. Tmem also handles concurrency nicely and
provides limited QoS settings to combat malicious DoS attempts.
Save/restore and live migration support is not yet provided.
Tmem is primarily targeted for an x86 64-bit hypervisor. On a 32-bit
x86 hypervisor, it has limited functionality and testing due to
limitations of the xen heap. Nearly all of tmem is
architecture-independent; three routines remain to be ported to ia64
and it should work on that architecture too. It is also structured to
be portable to non-Xen environments.
Tmem defaults off (for now) and must be enabled with a "tmem" xen boot
option (and does nothing unless a tmem-capable guest is running). The
"tmem_compress" boot option enables compression which takes about 10x
more CPU but approximately doubles the number of pages that can be
stored.
Tmem can be controlled via several "xm" commands and many interesting
tmem statistics can be obtained. A README and internal specification
will follow, but lots of useful prose about tmem, as well as Linux
patches, can be found at http://oss.oracle.com/projects/tmem .

If you use -MMD -MF then the correct .o filename is written to the
.*.d file as the compiler driver arranges everything. This was done
in 19010:275abe1c5d24 for the hypervisor.
In this patch we do the same elsewhere in the xen-unstable tree,
particularly tools/. Specifically:
* Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS.
* Remove -Wp,-MD... from every other Makefile
* Remove setting of DEPS from every other Makefile
* Ensure that every Makefile says -include $(DEPS)
* Ensure that every Makefile's clean target removes $(DEPS)
Some Makefiles were already halfway there, but often for a different
variable name eg PROG_DEP. The variable name is now standardised in
Rules.mk as DEPS.
I have done a test build with this change, on Debian etch.

The Xen tools contain a number of Python extensions written in C. The
C API to Python, used by these extensions, is not stable from one
version of Python to the next.
Our build system uses whatever version of Python is the default on the
build system at that time to build these extensions. However, the
actual scripts such as `xm' use #!/usr/bin/env python which uses
whichever version of Python is the default on the deployment system at
the time of invocation.
If for any reason these two versions of Python are not the same (eg,
because the system is built on one computer and executed on another,
or because the system's gains a more recent Python installation
alongside the original which changes the previous default), warnings
and failures occur.
In this patch I arrange for Python scripts to be installed via a
special wrapper around `install', which determines the build-time
Python version and path and then writes that into the #! line at the
point of `make install' (or `make dist'). (It can also be overridden
by setting PYTHON_PATH.)
