Will that work, if the guest with kernel that uses modern mode, kexecs to an older (but presumed reliable) kernel that only knows about legacy mode? I.e. will the replacement kernel, or (ideally) replacement driver on the rare occasion that is needed on a running kernel, be able to reset the device hard enough? -- Jamie -- 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
