If this isn't my lucky day. RH and Centos solved my problem even before I
defined it.

I saw the update earlier and didn't dare hope. I updated and it seems to
have solved the issue. On the host machine, I fired up virt-manager, started
the Fedora  guest and it's been up for a half hour.

Now I, too, can start complaining about Gnome 3. I've read it's like
Windows, but it's the spitting image of the Mac OS.
