<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.
|
|
|
|
|
