Yep, as near as I can tell, the window really does go away (though the app doesn't exit). There is one window created by the virt-manager app that acts "normal", all the other ones disappear when I try to bring them up under fvwm (unless I say unmanaged - I tried a vast collection of other style options with "ignore" in their name, but none of them helped :-). If I understood more about how to read pygtk code I might be able to guess why the one window is different than the other windows, but I don't really know gtk or python, much less the combination.
