Describe how we decide which host platforms to support for libvirt,
which in turn makes it easier to decide when a platform / software
version can be dropped.

+    <h1>Supported host platforms</h1>
+
+    <ul id=3D"toc"></ul>
+
+    <h2>Build targets</h2>
+
+    <p>
+      Libvirt drivers aim to support building and executing on multiple
+      host OS platforms. This document outlines which platforms are the
+      major build targets. These platforms are used as the basis for decid=
ing
+      upon the minimum required versions of 3rd party software libvirt dep=
ends
+      on. If a platform is no listed here, it does not imply that libvirt
+      won't work. If an unlisted platform has comparable software versions
+      to a listed platform, there is every expectation that it will work.
+      Bug reports are welcome for problems encountered on unlisted platfor=
ms
+      unless they are clearly older vintage that what is described here.
+    </p>
+
+    <h3>Linux OS</h3>
+
+    <p>
+      For distributions with frequent, short-lifetime releases (Fedora,
+      Ubuntu, OpenSUSE, etc), the project will aim to support all versions
+      that are not end of life by their respective vendors.
+    </p>
+
+    <p>
+      For distributions with long-lifetime releases (RHEL, Ubuntu LTS,
+      SLES, etc), the project will aim to support the most recent major
+      version at all times. Support for the previous major version will
+      be dropped 2 years after the new major version is released.
+    </p>
+
+    <h3>Windows</h3>
+
+    <p>
+      The project supports building with current versions of the MinGW
+      toolchain, hosted on Linux.
+    </p>
+
+    <h3>OS-X</h3>
+
+    <p>
+      The project supports building with the current version of OS-X,
+      with the current homebrew package set available.
+    </p>
+
+    <h3>FreeBSD</h3>
+
+    <p>
+      The project will aim to support the most recent major version
+      at all times. Support for the previous major version will
+      be dropped 2 years after the new major version is released.
+    </p>
+
+    <h2>Virtualization platforms</h2>
+
+    <p>
+      For hypervisor drivers which execute locally (QEMU, LXC, VZ,
+      libxl, etc), the set of supported operating system platforms
+      listed above will inform choices as to the minimum required
+      versions of 3rd party libraries and hypervisor management APIs.
+      If a hypervisor is not commonly shipped directly by any distro
+      listed above, (VMWare ESX, HyperV, VZ), the project aims to
+      support versions upto 5 years, or until the vendor discontinues
+      support, whichever comes first.
+    </p>
