Yes, there is. libxl changed significantly between Xen 4.1 and soon to be released Xen 4.2, so much so that the current libvirt libxl driver won't even build against Xen 4.2. In addition, the libxl driver does not have feature parity with the legacy xen driver. So lots of work to be done, but I have limited free cycles. I'm hoping to get another body or two at SUSE to help with this work. That said, xm/xend will still be included in Xen 4.2 and can be configured as the primary tool stack, allowing you to continue using your existing setup with Xen 4.2.
