libxl: Earlier detection of not running on Xen
Detect early on in libxl driver initialization if the driver should be loaded at all, avoiding needless initialization steps that only have to be undone later. While at it, move the detection to a helper function to improve readability. After detecting that the driver should be loaded, subsequent failures such as initializing the log stream, allocating libxl ctx, etc. should be treated as failure to initialize the driver.
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.
