Since you are running in software rendering mode (in a VM), gnome-shell
will use some CPU (since it doesn't have access to openGL acceleration)
but taking 70 to 80% CPU constantly is not a normal behavior. Did you
wait a bit until the desktop "settled" before doing your measure ? How
did you do your measure ?

If this was the case, you would see packagekitd in the CPU usage, not
gnome-shell.
