See my posting at
<https://lists.gnu.org/archive/html/guix-devel/2017-10/msg00185.html>:

When sharing the host's store ("guix system vm …"), Plasma takes 80
seconds (minimum) to start up after log-in to X11, when clicking the
menu-button, it takes 36 sec. for the menu to appear. This plain renders
such a VM unusable even for testing.

YMMV, but I call this in-acceptable and this is why I'm using a vm-image
("guix system vm-image …", which is much faster: Plase start-up 25 sec.,
Menu appears immediately.
