This error led those helping to question > about my qemu version and whether or not it supported xen. One of the experiments I was intending to do with that build was to see if xen would would work with Fedora's qemu. As you have just discovered the answer is no, though the tools configuration option allowing you tell xen where to find it seems to work. If you uninstall the qemu-system-x86 package or add the line device_model_version="qemu-xen-traditional" to your configuration file then your hvm guest should boot. Michael Young

CCing fedora xen list as well, maybe they have ideas. - Cole
