Support Xen 4.0 sysctl version 7
xen-unstable c/s 20762 bumped XEN_SYSCTL_INTERFACE_VERSION to 7. The interface change does not affect libvirt, other than xenHypervisorInit() failing since version 7 is not tried. The attached patch accommodates the upcoming Xen 4.0 release by checking for XEN_SYSCTL_INTERFACE_VERSION 7. If found, it sets XEN_DOMCTL_INTERFACE_VERSION to 6, which is also new to Xen 4.0.
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
