That doesn't really matter. It's okay if libvirt and QEMU model feature in a slightly different manner. For an example, see how kvmclock is changed from a <timer> element to an option of -cpu. I think I now agree with the libvirt folks. The effects of hv_crash are the same as the effects of <panic>, for example the VM will not anymore obey the "reboot on BSoD" setting, so it should be added to <panic>.
