Lennart, Bingo! The virtual serial port (on 3, btw) showed the system trying to boot. An error pointed out that in this iteration I had forgotten the -sd parameter, so no (virtual) hard disk.
I added -sd /export/armhf.qcow2 to the command, but still no hard disk in the /dev listing. I'm wondering if I have a problem with the dtb; I'll have to look into that. But at least I have something to work with now. Hopefully I can find why the disk isn't being recognized now. Thanks much!
