<h1>Bhyve driver</h1>
|
|
|
|
<ul id="toc"></ul>
|
|
|
|
<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/">bhyve.org</a>.

<h2><a name="uri">Connections to the Bhyve driver</a></h2>
|
|
<p>
|
|
The libvirt bhyve driver is a single-instance privileged driver. Some sample
|
|
connection URIs are:
|
|
</p>
|
|
|
|
<pre>
|
|
bhyve:///system (local access)
|
|
bhyve+unix:///system (local access)
|
|
bhyve+ssh://root@example.com/system (remote access, SSH tunnelled)
|
|
</pre>
|
|
|
|
<h2><a name="exconfig">Example guest domain XML configurations</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).
