<h1>Microsoft Hyper-V hypervisor driver</h1>
|
|
<ul id="toc"></ul>
|
|
<p>
|
|
The libvirt Microsoft Hyper-V driver can manage Hyper-V 2012 R2 and newer.
|
|
</p>
|
|
|
|
|
|
<h2><a id="project">Project Links</a></h2>
|
|
<ul>
|
|
<li>
|
|
The <a href="http://www.microsoft.com/hyper-v-server/">Microsoft Hyper-V</a>

</ul>
|
|
|

|
|
<h2><a id="uri">Connections to the Microsoft Hyper-V driver</a></h2>
|
|
<p>
|
|
Some example remote connection URIs for the driver are:
|
|
</p>
|
|
<pre>
|
|
hyperv://example-hyperv.com (over HTTPS)
|
|
hyperv://example-hyperv.com/?transport=http (over HTTP)
|
|
</pre>
|
|
<p>
|
|
<strong>Note</strong>: In contrast to other drivers, the Hyper-V driver
|
|
is a client-side-only driver. It connects to the Hyper-V server using
|
|
WS-Management over HTTP(S). Therefore, the
|
|
<a href="remote.html">remote transport mechanism</a> provided by the
|
|
remote driver and libvirtd will not work, and you cannot use URIs like
|
|
<code>hyperv+ssh://example.com</code>.
|
|
</p>
|
|
|
|
|
|
<h3><a id="uriformat">URI Format</a></h3>
|
|
<p>
|
|
URIs have this general form (<code>[...]</code> marks an optional part).
|
|
</p>
|
|
<pre>
|
|
hyperv://[username@]hostname[:port]/[?extraparameters]
|
|
</pre>
|
|
<p>
|
|
The default HTTPS ports is 5986. If the port parameter is given, it
|
|
overrides the default port.
|
|
</p>
|
|
|
|
|
|
<h4><a id="extraparams">Extra parameters</a></h4>
|
|
<p>
|
|
Extra parameters can be added to a URI as part of the query string
|
|
(the part following <code>?</code>). A single parameter is formed by a
|
|
<code>name=value</code> pair. Multiple parameters are separated by
|
|
<code>&</code>.
|
|
</p>
|
|
<pre>
|
|
?transport=http
|
|
</pre>
|
|
<p>
|
|
The driver understands the extra parameters shown below.
|
|

|
<h3><a id="auth">Authentication</a></h3>
|
|
<p>
|
|
In order to perform any useful operation the driver needs to log into
|
|
the Hyper-V server. Therefore, only <code>virConnectOpenAuth</code> can
|
|
be used to connect to an Hyper-V server, <code>virConnectOpen</code> and
|
|
<code>virConnectOpenReadOnly</code> don't work.
|
|
To log into an Hyper-V server the driver will request credentials using
|
|
the callback passed to the <code>virConnectOpenAuth</code> function.
|
|
The driver passes the hostname as challenge parameter to the callback.
|
|
</p>
|
|
<p>
|
|
<strong>Note</strong>: Currently only <code>Basic</code> authentication
|
|
is supported by libvirt. This method is disabled by default on the
|
|
Hyper-V server and can be enabled via the WinRM commandline tool.
|
|
</p>
|
|
<pre>
|
|
winrm set winrm/config/service/auth @{Basic="true"}
|
|
</pre>
|
|
<p>
|
|
To allow <code>Basic</code> authentication with HTTP transport WinRM
|
|
needs to allow unencrypted communication. This can be enabled via the
|
|
WinRM commandline tool. However, this is not the recommended
|
|
communication mode.
|
|
</p>
|
|
<pre>
|
|
winrm set winrm/config/service @{AllowUnencrypted="true"}
|
|
</pre>
|
|
|
|
|
|
<h2><a id="versions">Version Numbers</a></h2>
|
|
<p>
|
|
Since Microsoft's build numbers are almost always over 1000, this driver
|
|
needs to pack the value differently compared to the format defined by
|
|
<code>virConnectGetVersion</code>.
|
|
To preserve all of the digits, the following format is used:
|
|
</p>
|
|
<pre>major * 100000000 + minor * 1000000 + micro</pre>
|
|
<p>
|
|
This results in <code>virsh version</code> producing unexpected output.
