As an aside, I recently attempted to set up a Xen based system using libvirt on Fedora, and I was initially confused by the two drivers, and completely messed up my setup because of it. I think simply from a usability point of view, it makes a lot of sense to eliminate the old code and set up the libxl driver to be the "successor" of the old xen driver. -- 真実はいつも一つ！/ Always, there's only one truth! -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
