I really dislike using GObject data this way. If there's no better way to handle
it, I suppose it's OK, but I'd prefer a different design.

This session-connected change (as well as the two static functions directly
above seem unrelated to the GtkApplication change. Can they be moved into a
separate commit, or are they inter-related somehow?

consider renaming this function to something like
virt_viewer_app_on_application_startup() to prevent confusion with
virt_viewer_app_start()

I would add a return here since it doesn't really make sense to call
g_application_hold() after we try to quit (even though it won't have any
impact).

I don't like this approach. A version is not an error. It should set a status of
0 (not 1), but should return TRUE to indicate that we've fully handled the
commandline and the application should exit. Also, I don't see any reason that
the version handling couldn't be done in the common VirtViewerApp class. I don't
think there's any problem with printing the OS ID in the virt-viewer version
output.
