I saw similar hang during the test when libvirtd was running but not
responding (trapped in a gdb session, for example). However, it's much longer
than 21 seconds in that case :-)

I wonder why test:/// uri ever tries to connect anywhere... isn't that
internal to libvirt and present in all clients?
