Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

Eric Blake acf522e85a examples: Avoid gnulib, have standalone examples
Commit 0c6ad476 updated gnulib, which rearranged some of the
conditions in gnulib wrapper headers such that compilation
started failing on BSD systems when the normal system <unistd.h>
tried to include another system header but instead got a
gnulib wrapper header in an incomplete state; this is because
gnulib headers only work if <config.h> is included first.

Commit b6f78259 papered over the symptoms of that by including
<config.h> in all the examples.  But this logic is backwards -
if our examples are truly meant to be stand-alone, they should
NOT depend on how libvirt was configured, and should NOT
depend on the gnulib fixes for system quirks.  In particular,
if an example does not need to link against libgnulib.la,
then it also does not need to use -Ignulib in its compile
flags, and likewise does not need to include <config.h> since
none of the gnulib wrapper headers should be interfering.

So, revert (most of) b6f78259 (except for the bogus pre-patch
use of "config.h" in admin/logging.c: if config.h is included,
it should be via <> rather than "", and must be before any
system headers); then additionally nuke all mention of
<config.h>, -Ignulib, and -llibgnu.la, making all of the
examples truly standalone.

Build Status CII Best Practices

Libvirt API for virtualization

Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.

Further information about the libvirt project can be found on the website:

https://libvirt.org

License

The libvirt C API is distributed under the terms of GNU Lesser General Public License, version 2.1 (or later). Some parts of the code that are not part of the C library may have the more restrictive GNU General Public License, version 2.1 (or later). See the files COPYING.LESSER and COPYING for full license terms & conditions.

Installation

Libvirt uses the GNU Autotools build system, so in general can be built and installed with the usual commands. For example, to build in a manner that is suitable for installing as root, use:

$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install

While to build & install as an unprivileged user

$ ./configure --prefix=$HOME/usr
$ make
$ make install

The libvirt code relies on a large number of 3rd party libraries. These will be detected during execution of the configure script and a summary printed which lists any missing (optional) dependencies.

Contributing

The libvirt project welcomes contributions in many ways. For most components the best way to contribute is to send patches to the primary development mailing list. Further guidance on this can be found on the website:
