* send, recv: we use write & read for sockets so don't need these portability wrappers * ioctl, fcntl, fcntl-h: any usage of these is conditionally compiled and excludes Windows * ttyname_r: this exists in all supported platforms that we require now * environ: the tests explicitly declare this global variable * intprops: the code has been converted / simplified * nonblocking: we have a custom impl now to work with our own sockets wrappers * openpty: custom checks in configure.ac cope with portability * accept, bind, connect, getpeername, getsockname, listen, setsockopt, socket: code needing Windows portability uses our wrapper functions * close: avoids abort when passed invalid FD on Windows. Our VIR_FORCE_CLOSE wrapper avoids calling close(-1) and it is reasonable to abort in other scenarios in the RPC client * physmem: the gnulib code has been partially imported * warnings, manywarnings: copy the files directly into our local m4 dir * verify: replaced by G_STATIC_ASSERT * pthread_sigmask: none of the fixed portability problems affect libvirt's usage on current supported platforms * termios: the header is now conditionally included only when needed * time_r: replaced with GDateTime APIs Reviewed-by: Pavel Hrdina <phrdina@redhat.com> Signed-off-by: Daniel P.

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.

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

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, however, we mandate to have the build directory different than the source directory. For example, to build in a manner that is suitable for installing as root, use:
$ mkdir build && cd build
$ ../configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install
While to build & install as an unprivileged user
$ mkdir build && cd build
$ ../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:

Contact
The libvirt project has two primary mailing lists:
- libvirt-users@redhat.com (for user discussions)
