>From d6802cee0c50e9d9d58345ecf94a3f3e2933d190 Mon Sep 17 00:00:00 2001 From: Jim Fehlig Date: Thu, 10 Feb 2011 15:42:34 -0700 Subject: [PATCH] Add libxenlight driver Add a new xen driver based on libxenlight [1], which is the primary toolstack starting with Xen 4.1.0. The driver is stateful, runs privileged only, and is accessed with libxl:/// URI.

    libxenlight hypervisor driver

    + + + +

    + The libvirt libxenlight driver provides the ability to manage virtual + machines on any Xen release from 4.1.0 onwards. +

    + +

    Deployment pre-requisites

    + +

    + This driver uses Xen's libxenlight toolstack, which is the default + toolstack configuration starting with Xen 4.1.0. The traditional + xm/xend toolstack is still provided, but it is no longer maintained + and may be removed in a future Xen release. +

    + +

    + The libxenlight toolstack uses xenstored and blktap2. Ensure + xenstored is running, or use the xencommons init script provided. + Ensure your kernel supports the blktap2 module and it is loaded. +

    + +

    Connections to libxenlight driver

    + +

    + The libvirt libxenlight driver is a stateful, privileged driver, + with a driver name of 'libxl'. Some example conection URIs for + the libxenlight driver are: +

    + +
    +libxl:///                      (local access, direct)
+libxl://example.com/           (remote access, TLS/x509)
+libxl+tcp://example.com/       (remote access, SASl/Kerberos)
+libxl+ssh://root@example.com/  (remote access, SSH tunnelled)
+
    + +

    Example domain XML config

    + +

    + The libxenlight toolstack attempts to be compatible with the + legacy xm/xend toolstack, supporting the traditional python + configuration files (xen-xm). Fortunately, the libvirt XML + syntax is unchanged with the libxenlight driver. Consult + the Xen driver examples. +
