OK, that’s terrible indeed. So that’s with ‘-enable-kvm’ on the qemu
command line, right?

25 seconds to start up is still a lot (in ‘guix system vm’ GNOME is
usable and much faster to start). It would be nice to see if that comes
from I/O or something else. Is there something we’re doing wrong
(independently of the VM) or is it expected for Plasma startup to be
this slow?
