The numbering (Virtual-0 vs Virtual-1) is expected - this is not an issue.

Do you actually get the choice of additional displays in virt-viewer (not in the guest) ?
Under the top menu "View -> Displays" you should have a list of available displays. Do you see them ? Are they enabled or grayed out ?

Ah, that is some kind of progress!

This is not visible in the integrated viewer in virt-manager, but when I launch virt-viewer on its
own, yes, I do get the option of two displays. And enabling them both does allow me to launch
a second display.

I cannot then launch the display settings in the guest, however; it segfaults right away. I'll look into 
that. But xrandr does report two displays; the second one is 2135 x 1647, though. Not clear why I
still don't get a 4K option with QXL.

If I try this with the virtio device (instead of QXL) with two heads, it's similar: a separate virt-viewer 
instance allows me to launch two displays; in this case xrandr reports 4K displays. But as before, 
the display settings manager segfaults right away.

Exploring further.
