<p>
Libvirt is known to work as a client (not server) on Windows XP
(32-bit), and Windows 7 (64-bit). Other Windows variants likely work
as well but we either haven't tested or received reports for them.
</p>
<h2>
<a name="installer" id="installer">Experimental installation package</a>
</h2>
<p>
A windows installation package is in development. An experimental
version is available here:
</p>
<a href="http://libvirt.org/sources/win32_experimental/Libvirt-0.8.8-0.exe">http://libvirt.org/sources/win32_experimental/Libvirt-0.8.8-0.exe</a>
<p>
<b>It is not production ready.</b>
</p>
<p>
This version includes the libvirt development headers and libraries
for compiling against, the virsh shell with its needed dependencies,
and untested Python bindings.
</p>
<h3>
<a name="caveats" id="caveats">Caveats</a>
</h3>
<ul><li>
This installer just repackages the files compiled using Matthias
Bolte's msys_setup scripting (described below).
</li><li>
This is a .exe installer, created using NSIS. We're looking into
something to create .msi installers as well.
</li><li>
The script for the NSIS installer is available online
<a href="https://github.com/justinclift/nsis_libvirt_installer">here</a>.
</li></ul>
<h3>
<a name="knowninstallerprobs" id="knowninstallerprobs">Existing problems with this installer we know about</a>
</h3>
<p>
These are problems we know about, and need to be fixed in subsequent
versions of the installer (assistance welcomed):
</p>
<ul><li>
New versions install over other libvirt versions
<br /><br />
If a version of this installer has installed libvirt on the system
already, this installer will automatically suggest the same
installation location, then overwrite the version already there
without checking.
<br /><br />
This is fairly non-optimal, and should be fixed. What should
probably happen, is for this installer to detect an existing
installation then offer to either uninstall it first or ask for a
new installation location.
<br /><br /></li></ul>
<h2>
<a name="conntypes" id="conntypes">Connection types</a>
</h2>
<p>
These connection types are known to work:
</p>
<ul><li>QEMU with TLS (qemu+tls://)</li><li>QEMU with direct TCP (qemu+tcp://)</li><li>VMware ESX (esx://)</li><li>VMware VPX (vpx://)</li></ul>
<p>
These connection types are known not to work:
</p>
<ul><li>QEMU with SSH (qemu+ssh://)</li></ul>
<p>
All other connection types may or may not work, and haven't been
tested.
</p>
<p>
Please let us know either the results (either way) if you do.
</p>
<p>
<b>Special note</b> - Support for VirtualBox *on windows* was added in
libvirt 0.8.7, so reports on success and failure if you're using that
would be really helpful and appreciated.
</p>
<p>
<b>WARNING - The qemu+tcp:// connection type passes all traffic
without encryption. This is a security hazard, and should <i>not</i>
be used in security sensitive environments.</b>
</p>
<h2>
<a name="esx" id="esx">Connecting to VMware ESX/vSphere</a>
</h2>
<p>
Details on the capabilities, certificates, and connection string
syntax used for connecting to VMware ESX and vSphere can be found
online here:<br /></p>
<a href="http://libvirt.org/drvesx.html">http://libvirt.org/drvesx.html</a>
<h2>
<a name="tlscerts" id="tlscerts">TLS Certificates</a>
</h2>
<p>
TLS certificates need to have been created and placed in the correct
locations, before you will be able to connect to QEMU servers over
TLS.
</p>
<p>
Information on generating TLS certificates can be found here:
</p>
<a href="http://wiki.libvirt.org/page/TLSSetup">http://wiki.libvirt.org/page/TLSSetup</a>
<p>
These instructions are for *nix, and have not yet been adapted for
Windows. You'll need to figure out the Windows equivalents until
that's done (sorry). If you can help us out with this, that would be
really welcome.
</p>
<p>
The locations of the TLS certificates and key file on Windows are hard
coded, rather than being configurable.
</p>
<p>
The Certificate Authority (CA) certificate file must be placed in:
</p>
<ul><li>%APPDATA%\libvirt\pki\CA\cacert.pem</li></ul>
<p>
The Client certificate file must be placed in:
</p>
<ul><li>%APPDATA%\libvirt\pki\libvirt\clientcert.pem</li></ul>
<p>
The Client key file must be placed in:
</p>
<ul><li>%APPDATA%\libvirt\pki\libvirt\private\clientkey.pem</li></ul>
<p>
On an example Windows 7 x64 system here, this resolves to these paths:
</p>
<ul><li>C:\Users\someuser\AppData\Roaming\libvirt\pki\CA\cacert.pem</li><li>C:\Users\someuser\AppData\Roaming\libvirt\pki\libvirt\clientcert.pem</li><li>C:\Users\someuser\AppData\Roaming\libvirt\pki\libvirt\private\clientkey.pem</li></ul>

</h2>
<p>
Libvirt can be compiled on Windows using the free
<a href="http://www.mingw.org/">MinGW compiler</a>.
</p>
<h3>
<a name="msys_setup" id="msys_setup">MSYS Build script</a>
</h3>
<p>
The easiest way is to use the <b>msys_setup</b> script, developed by
Matthias Bolte. This is actively developed and kept current with
libvirt releases:
</p>
<a href="https://github.com/photron/msys_setup">https://github.com/photron/msys_setup</a>
<h3>
<a name="cross-compile" id="cross-compile">Cross compiling</a>
</h3>
<p>
You can also cross-compile to a Windows target from a Fedora machine
using the packages available
<a href="http://hg.et.redhat.com/misc/fedora-mingw--devel/">from the Fedora MinGW project</a>
(which includes a working libvirt specfile).
</p>
<h3>
<a name="configure" id="configure">By hand</a>
</h3>
<p>
Use these options when following the instructions on the
<a href="compiling.html">Compiling</a> page.
