<p>
Bhyve is a FreeBSD hypervisor. It first appeared in FreeBSD 10.0. However, it's
recommended to keep tracking FreeBSD 10-STABLE to make sure all new features
of bhyve are supported.
In order to enable bhyve on your FreeBSD host, you'll need to load the <code>vmm</code>
kernel module. Additionally, <code>if_tap</code> and <code>if_bridge</code> modules
should be loaded for networking support.
</p>
<p>
Additional information on bhyve could be obtained on <a href="http://bhyve.org/" shape="rect">bhyve.org</a>.

<p>
The libvirt bhyve driver is a single-instance privileged driver. Some sample
connection URIs are:
</p>
<pre xml:space="preserve">
bhyve:///system (local access)
bhyve+unix:///system (local access)
bhyve+ssh://root@example.com/system (remote access, SSH tunnelled)
</pre>

<a name="exconfig" shape="rect" id="exconfig">Example guest domain XML configurations</a>
<a class="headerlink" href="#exconfig" title="Permalink to this headline">¶</a>
</h2>
<h3>Example config</h3>
<p>
The bhyve driver in libvirt is in its early stage and under active development. So it supports
only limited number of features bhyve provides. All the supported features could be found
in this sample domain XML.
</p>
<p>
A limitation that is not obvious from this sample domain XML is that currently only a
single network and a single disk device are supported for each domain (as PCI slot allocation code
in libvirt bhyve driver is yet to be implemented).
