When attempting to run:
libvirt.git/_build # ./run --selinux ./src/libvirtd
the following error is thrown:
Refusing to change selinux context of file './src/libvirtd' outside build directory
which is obviously wrong. The problem is 'being inside of build
directory' is detected by simple progpath.startswith(builddir).
While builddir is an absolute path, progpath isn't necessarily.
And while looking into the code, I've noticed chcon() function
accessing variable outside its scope when printing out the path
it's working on.

When running libvirt from the build directory with the 'run' script, it
will run as unconfined_t. This can result in unexpected behavior when
selinux is enforcing due to the fact that the selinux policies are
written assuming that libvirt is running with the
system_u:system_r:virtd_t context. This patch adds a new --selinux
option to the run script. When this option is specified, it will launch
the specified binary using the 'runcon' utility to set its selinux
context to the one mentioned above. Since this may require root
privileges, setting the selinux context is not the default behavior and
must be enabled with the command line switch.

When using thue 'run' script to launch a daemon, it is intended to
temporarily stop the systemd units and re-start them again after.
When using this script over an SSH connection, it will get SIGHUP
if the connection goes away, and in this case it fails to re-start
the systemd units. We need to catch SIGHUP and turn it into a
normal python exception. For good measure we do the same for
SIGQUIT and SIGTERM too. SIGINT already gets turned into an
exception by default which we handle.

The run script tries to detect when a daemon is being run in order to
shutdown other systemd unit files that clash. As implemented this
only works if the daemon name is the first argument. This won't be the
case if running via GDB or strace eg
./run strace -e trace=openat ./build/src/virtqemud
We need to check all argv to find which might be a daemon path/name.

When testing locally built daemons on a systemd host there can be quite
a few systemd units that need temporarily stopping, and ideally
restarting after the test is complete. This becomes a massive burden
when modular daemons are running and you want to test libvirtd, as a
huge number of units need stopping.
The run script can facilitate this usage by looking at what units are
running and automatically stopping any that are known to conflict with
the daemon that is about to be run. This is only done when running as
root, since non-root libvirtd does not (currently) use systemd.

You normally want to run the locally compiled copy of virsh. Trying
to run the installed version with the locally compiled library is a
recipe for problems with missing symbols and so on. By adding tools
to the path we can ensure that (eg) the libguestfs test suite will use
compatible copies of the library and virsh.

The Perl bindings for libvirt use the test driver for unit tests. This
tries to load the cpu_map/index.xml file, and when run from an
uninstalled build will fail.
The problem is that virFileActivateDirOverride is called by our various
binaries like libvirtd, virsh, but is not called when a 3rd party app
uses libvirt.so
To deal with this we allow the LIBVIRT_DIR_OVERRIDE=1 env variable to be
set and make virInitialize look for this. The 'run' script will set it,
so now build using this script to run against an uninstalled tree we
will correctly resolve files to the source tree.

We're using virFileFindResourceFull() to locate resources
nowadays, which makes exporting these information in the
environment unnecessary: see
virDriverLoadModule() for LIBVIRT_DRIVER_DIR
virLockManagerPluginNew() for LIBVIRT_LOCK_MANAGER_PLUGIN_DIR
virLockManagerLockDaemonConnectionNew() for VIRTLOCKD_PATH
doRemoteOpen() for LIBVIRTD_PATH
As further proof that we don't need to expose the information
this way anymore, we're not even exporting VIRTLOGD_PATH, which
would be necessary if virLogManagerConnect() didn't already
take care of that for us.

It makes no sense to prohibit reuse of the wrapper in other LGPL
projects, since most of libvirt is designed to be LGPL. Of
course, when using the wrapper to wrap a GPL program, the combined
result is still effectively GPL, but that shouldn't force us to
license the wrapper as GPL in isolation.
* run.in: Relicense to LGPLv2+.
Nothing in run required bash, except for the shebang. On systems
where /bin/bash doesn't exist (I hit it on FreeBSD), using /bin/sh
instead fixes a 'make check' failure:
gmake[3]: Entering directory `/usr/home/dummy/libvirt/python'
GEN check-local
/usr/local/bin/bash: ../run: /bin/bash: bad interpreter: No such file or directory
* run.in: Use /bin/sh, not bash.
This adds a 'lockd' lock driver which is just a client which
talks to the lockd daemon to perform all locking. This will
be the default lock driver for any hypervisor which needs one.
* src/Makefile.am: Add lockd.so plugin
* src/locking/lock_driver_lockd.c: Lockd driver impl

With this script you can run libvirt programs without needing to
install them first. You just have to do for example:
./run ./tools/virsh [args ...]
If you are already in the tools/ subdirectory, then the following
command will also work:
../run ./virsh [...]
You can also run the C programs under valgrind like this:
./run valgrind [valgrind opts...] ./program
or under gdb:
./run gdb --args ./program
This also works with sudo (eg. if you need root access for libvirt):
sudo ./run ./tools/virsh list --all
Derived from libguestfs and simplified. The ./run script in
libguestfs is much more sophisticated:
