<h1>QEMU/KVM hypervisor driver</h1>
|
|
<p>
|
|
The libvirt QEMU driver can manage any QEMU emulator from version 0.8.1
|
|
or later. It can also manage anything that provides the same QEMU command
|
|
line syntax and monitor interaction. This includes KVM, and Xenner.
|
|
</p>
|
|
<h2>Deployment pre-requisites</h2>
|
|
<ul><li>
|
|
<strong>QEMU emulators</strong>: The driver will probe <code>/usr/bin</code>
|
|
for the presence of <code>qemu</code>, <code>qemu-system-x86_64</code>,
|
|
<code>qemu-system-mips</code>,<code>qemu-system-mipsel</code>,
|
|
<code>qemu-system-sparc</code>,<code>qemu-system-ppc</code>. The results
|
|
of this can be seen from the capabilities XML output.
|
|
</li><li>
|
|
<strong>KVM hypervisor</strong>: The driver will probe <code>/usr/bin</code>
|
|
for the presence of <code>qemu-kvm</code> and <code>/dev/kvm</code> device
|
|
node. If both are found, then KVM fullyvirtualized, hardware accelerated
|
|
guests will be available.
|
|
</li><li>
|
|
<strong>Xenner hypervisor</strong>: The driver will probe <code>/usr/bin</code>
|
|
for the presence of <code>xenner</code> and <code>/dev/kvm</code> device
|
|
node. If both are found, then Xen paravirtualized guests can be run using
|
|
the KVM hardware acceleration.
|
|
</li></ul>
