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.

This moves all generic path variables to a new the config/Paths.mk.in
input source file to be processed at configure time, tons of files use
these so this just share them. This also paves the way to let us
easily dynamically configure these with autoconf, for now we leave the
same presets as was present before.
This work was prompted by looking for an autoconf way to do
replacements for the hotplug global file, while at it I realized
that a few other files use the same variables and have in places
around the tree the same constructs for generating their own
files. This makes use of the old buildmakevars2file() but generalizes
the definition of the paths at configure time and spreads the
new definitions out throughout the build system.
This has no impact on building the hypervisor and extras/mini-os,
you do not need to, and are not expected to, run configure to build
those targets.
While at it lets add some documentation on the for the two files on
the source file, we can expand further details on the wiki [0].

The current -maarch64elf fails when cross-building arm64 on Ubuntu Raring due
to a missing file "ldscripts/aarch64elf.xr". This is undoubtedly an Ubuntu gcc
bug, hwever when investigating I found that this option was not necessary at
all since we provide an explicit linker script when linking the hypervisor
(AFAICT all -m<foo> does is override the default linker script).
LDFLAGS_DIRECT is also used when linking the intermediate built-in.o files but
-m<emulatin> is not needed for this since it isn't linking the final image and
we are calling the linker with the correct, cross if necessary, name.
However it does appear to be potentially useful to supply -EL in both cases to
ensure that we get little endian images. (I just happened to spot that Linux
does this, for both arm and arm64, although I expect we are unlikely to trip
over such toolchains these days).
