The kernel doesn't check the vendor ID at the moment, but presumably the idea of the field is to allow the kernel to work around implementation bugs/blacklist/whatever if necessary. If that's the theory then it would make more sense for QEMU and kvm-tool to use IDs that say "this is the QEMU implementation" and "this is the kvm-tool implementation". (I picked 0x554D4551 for QEMU...) -- PMM -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
