[libvirt] [PATCH 0/3] Basic libxenlight driver

Hi, I started working on a libxenlight driver for libvirt a few weeks ago. By that time I didn't knew Jim Fehlig was also working on a driver for that api: http://article.gmane.org/gmane.comp.emulators.libvirt/33024 Because I already did some work and there is no driver from Jim yet, I am posting my current version of the driver here. It is a driver for the libxl (libxenlight) interface from the upcoming xen 4.1. This driver is divided into 3 patches, the first adds the driver without changing anything in libvirt, the second one integrates it into the build system of libvirt. The last one is self explanatory. However there are a few caveats. 1. The driver offers only basic functionality like: suspend, resume, pinvcpu, etc. create, restore, definexml and others are not yet implemented. 2. The driver supports libvirtxml <-> xen-xm conversion, thanks to the unified xen driver which already offered this functionality. But since this driver is not part of xen unified, I had to copy this functionality, rather than reusing it. 3. To compile libvirt with this driver, there is a new flag --with-xenlight. To fix some linker errors, libvirt has to link against several additional libraries now which are used in xen's libxenlight. These libraries are not directly used within libvirt, but I believe that some of them are GPL licensed, so that could be an issue. 4. To compile the driver you may need to copy the libxl_utils.h from tools/libxl of your xen-source directory to an include dir in your PATH. Right now this file is not copied when installing xen, but I will talk with the xen developers about that. Please let me know what you think about it.
