The differences between the command line that crashes and yours are: - yours doesn't have "aio=native" in the -drive declaration. - yours has some differences in the virtio-serial device declaration. - yours has some differences in the virtserialport device declaration. As time permits I'm going to try each of those differences individually. Thanks, -Rick
