[libvirt PATCH v5 03/20] conf: Add hvf domain type

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Roman Bolshakov <r.bolshakov@xxxxxxxxx>

QEMU supports Hypervisor.framework since 2.12 as hvf accel.
Hypervisor.framework provides a lightweight interface to run a virtual
cpu on macOS without the need to install third-party kernel
extensions (KEXTs).

It's supported since macOS 10.10 on machines with Intel VT-x feature
set that includes Extended Page Tables (EPT) and Unrestricted Mode.

 The root element required for all virtual machines is named ``domain``. It has
 two attributes, the ``type`` specifies the hypervisor used for running the
-domain. The allowed values are driver specific, but include "xen", "kvm", "qemu"
+domain. The allowed values are driver specific, but include "xen", "kvm",
+"hvf" (:since:`since 8.0.0 and QEMU 2.12`), "qemu"
 and "lxc". The second attribute is ``id`` which is a unique integer identifier
 for the running guest machine. Inactive machines have no id value.
