The accelerator module generates an error part-way into the Linux boot sequence (right after disk probing). dmesg shows that shadow faulting the GDT is failing but that's occuring a bit before it bails out (according to the timestamps). I can provide a script that can take a built Xen tree and launchs qemu with Xen automatically (you could provide an empty disk since it dies long before it mounts the disk). It's not as simple as just passing a -kernel because Xen needs to be booted via multiboot. Regards, Anthony Liguori >Paul > > >
