This will allow us to share the same module list with
systemd, and lets us upkeep it in one place. Document this
while at it on the top level README and expand on the wiki:
http://wiki.xen.org/wiki/Category:Host_Configuration#Kernel_modules
In order to upkeep parallelism builds be explicit about the
requirement to complete all actions before any installation
targets.

As it stands oxenstored will be used by default if ocaml tools are
found, the init system will also try to use oxenstored first if its
found otherwise the cxenstored will be used. Lets simplify the init
script and let users be explicit about the preference through configure.
This adds support to let you be explicit about the xenstored preference,
you can only use one of these two options:
./configure --with-xenstored=xenstored
./configure --with-xenstored=oxenstored
We continue with the old behaviour and default oxenstored will be used
but only if you have ocaml dependencies. Since the xenstored preference
is explicit now and since we require configure substitutions for it we
make use of the AX_XEN_EXPAND_CONFIG() helpers as otherwise substitution
for SBINDIR is not propagated from the top level configuration.
All this allows us to simplify the init script to use the configured
xenstore from the start. We update the sysconfig/default xencommons file
with the paths for the different options though, this can be used by
users to override the default xenstored, this follows the old behaviour
but we now just explicitly provide the full configured paths for users.
As before, changing the xenstore requires a reboot.
In order to help with documentation we update the README with some
details on configure usage refer to the wiki [0] [1] [2] for more elaborate
details.
Since we are now parsing an entry within Paths.mk.in on tools we let
the move the parsing of the file to be the tool's configure.

+xenstore: xenstored and oxenstored
+====================================
+
+Xen uses a configuration database called xenstore [0] to maintain configuration
+and status information shared between domains. A daemon is implemented as part
+of xenstore to act as an interface for access to the database for dom0 and
+guests. Two xenstored daemons are supported, one written in C which we refer
+to as the xenstored (sometimes referred to as cxenstored), and another written
+in Ocaml called oxenstored. Details for xenstore and the different
+implementations can be found on the wiki's xenstore reference guide [1] and
+the xenstored [2] page. You can choose which xenstore you want to enable as
+default on a system through configure:
+
+ ./configure --with-xenstored=xenstored
+ ./configure --with-xenstored=oxenstored
+
+By default oxenstored will be used if the ocaml development tools are found.
+If you enable oxenstored the xenstored will still be built and installed,
+the xenstored used can be changed through the configuration file:
+
+/etc/sysconfig/xencommons
+or
+/etc/default/xencommons
+
+You can change the preferred xenstored you want to use in the configuration
+but since we cannot stop the daemon a reboot will be required to make the
+change take effect.

From: "Luis R. Rodriguez" <mcgrof@suse.com>
This adds the systemd xen service / module files and integrates
support into the build system.
This goes in with AX_AVAILABLE_SYSTEMD() which will enable
systemd if development libraries have been found on your
build system. If you don't have systemd on target systems
for binaries built with systemd then the binary will not
work, you must explicitly disable systemd support if you
do not want to build systemd support.
When systemd libraries are present only systems that
have booted into systemd go through the systemd initialization,
otherwise the SysVinit is used.
These are originally based on the Fedora systemd files.
Changes made from Fedora's systemd files:
* split sockets into two files to claim different permissions
* Use /bin/sh -c exec to for a simple launcher implementation
* enables systemd socket activation for C xenstored and Ocaml
oxenstored
* use sd_notify(), so change the service to Type=notify, because of
this we remove the PIDFile specification as we don't care for it, and let
systemd do its magic for us, this also means we don't have to fork
so we use --no-fork with systemd
* defines a modules-load.d, its original source file will be shared
between systemd and old init systems
* simplify service files with ConditionVirtualization=xen which uses
the built in systemd virtualization backend detection, these
service files will not be available to start on systems that do not
boot with xen as a hypervisor
* use autoconf to replace @variable@ paths for us which piggy
backs on top of the latest autoconf changes to xen
* removes oxenstored service file in favor of a system variable which
controls which which xentored to use at run time, we avoid multiple
service files this way.
* simplifies startup to not require polling on the sockets
as initial socket management is handled by systemd, we just
take on the socket later once anything pokes at it, a simple nc -U
(as root) on any of the sockets files can activate the service for example.
Anything queued up will be sent to us once we start. Socket activation
should in theory also let us dynamically switch between xenstores but more
importantly we could upgrade xenstored while keeping all active
socket communication queued up, but in order to take advantage of
this we eventually would need to remove the requirement of not being
able to bring down the xenstored. Even though active sockets are
supported since most libxl communication doesn't triggger a check
on the unix socket first administrators are encouraged to enable
the xenstored.service to triggger an initialization of the xenstored
upon bring up. Some systems also never use unix sockets for
communication with the xenstored and as such active sockets will
not be used there.
* allow for xenstored configuration through *either* of these
configuration files:
- /etc/sysconfig/xenstored
- /etc/default/xenstored
The /etc/default/xenstored will let debian based systems do
the same, while SUSE/OpenSUSE/Fedora/RedHat can keep on chugging
with sysconfig. We leave these files all commented out by default
though given that for systemd we want to encourage not using them.
* ensures we create the run directory as most systems will likely
be using a tmpfs for run dirs for the pid files
* Some systems define the selinux context in the systemd Option for the
/var/lib/xenstored tmpfs:
Options=mode=755,context="system_u:object_r:xenstored_var_lib_t:s0"
For the upstream version we remove that and let systems specify the
context on their system /etc/default/xenstored or /etc/sysconfig/xenstored
$XENSTORED_MOUNT_CTX variable, with a default to none.
* takes advantage of the shared xendomains helper for the xendomains
service
* Add the new dom0 that gets kicked off for disk backend access into
its own systemd service associated to xen
We end up with these systemd files:
General requirements:
* proc-xen.mount
* var-lib-xenstored.mount
xenstored:
* xenstored.service
* xenstored.socket
* xenstored_ro.socket
* xenconsoled.service
* xen-qemu-dom0-disk-backend.service.in
Optional:
* xendomains.service
* xen-watchdog.service
As for integration with xen, we house keep all the systemd files
under a new directory tools/hotplug/Linux/systemd/ and will be targeted
by default when building on Linux systems if systemd development
libraries are present at build time.
The systemd files will be sanitized for meta @VARIABLES@ upon
configuration and installed upon the install target. Systems that
do not use systemd can still get systemd service unit files installed
if the build system enabled systemd support, this however does not
mandate a requirement of having systemd libraries present. Old init
scripts are always installed.
If you don't specify a prefix you will end up with the services
files under /usr/local/lib/systemd/system/ by default, and systemd
modules-load.d conf files under /usr/local/lib/modules-load.d/ which
systemd does look for (although it seems this is not documented).
Distributions are expected to provide their /usr/ prefix to end up in
the more generic location upon distribution install at
/usr/lib/systemd/system/ and /usr/lib/modules-load.d/ respectively.

+Systemd support
+===============
+
+If you have systemd development packages installed you can build binaries
+with systemd support. Systemd support is enabled by default if you have
+systemd development libraries present. If you want to force enable systemd to
+ensure you build binaries with systemd support you can use the --enable-systemd
+flag. Likewise if you want to force disable systemd you can use:
+
+ ./configure --disable-systemd
+
+For more details refer to the xen xenstored systemd wiki page [3].
