Ok, I have some more information. If I use virt-viewer from git, when I
connect, I get the same black screen and it sits there with no errors. If I
then close virt-viewer and reconnect while the VM is running, I get the
following spam in the console:

(virt-viewer:18260): GSpice-CRITICAL **: spice_egl_update_display:
assertion 'd->egl.image != NULL' failed

Hopefully it helps,
